ASP 61
MARTLIEW
90$$ which is cheap for a ball bearing/ABC motor.
I also notice that a 61 size engine called the "Mutunc" is advertized for
sale at only 60$in RCM. Anybody got any experience with this engine?
I thinking about a .61 motor and am wondering if it's really worthwhile
spending 140$ for a Super Tigre compared to 100$$ for a Taiwanese
engine...?
Thanks...Martin

would also suggest the Tiger Shark (TSI) 61 ABC Long Stroke. These
engines are great and the cost is about the same as the ASP but you get an
Aluminum spinner with the TSI. The TSI engines also compare well with
ST.61 ABC.

The 61 ST will out perform any TW engine out there, and its
a BG to see your plane scream past the other lesser 61s at the field.

I could be totally wrong on this, but I was under the impression that ASP
engines are made in mainland China, aka "Red China". Thunder Tiger engines
are made in Taiwan,
aka "Republic of China". If I'm wrong, go ahead and slap my hands. It may
not seem a big difference to us, but I think it's a very big difference to
the people that live in that part of the world!

Not according to the U.S. State Department! They have an official
one-China policy, and that covers the big red one. The poor folks in
Taiwan are left out in the cold, since we can't recognize "two Chinas"
... ain't politics grand! Ahhh... the Nixon legacy.
As I understand it, we have agreed to treat Taiwan like a rebellious
Chinese province, and that was why there was such a stink a few months
ago when we granted a visa to the Taiwanese President (or was it the
Prime Minister?). Mainland (Red) China took great offense at our
"official" recognition of Taiwan, while we only intended it to be a
humanitarian gesture, or so the State Department said!
Meanwhile, big business has embraced Red China, as evidenced by the
proliferation of products being made there. Never mind the political
prisoners, the forced abortions, the lack of civil (and human) rights,
the prison labor camps, the students mowed down by tanks, we can save
a buck on every pair of jeans (or glow engine) we buy... What a deal!
Besides that, I've heard so many "glowing" reports on ASP engines, I
can't wait to put one in a Sukhoi. The only problem is I can't decide
if I should call it "Big Red" or "The Harry Wu Special." ;)
I'll get off my soap box now...

I haven't used a Super Tigre .61, but I have a Magnum (Thunder Tiger)
Pro .45 and the Thunder Tiger Pro .46. The Pro .45 is a very good
engine and the Pro .46 is EXCELLENT. Compared to the OS .46 SF (I have
owned three of these), the Super Tigre .45 (I know a number of people
that own these), I would take the Thunder Tiger Pro .46. All three
engines are very reliable, but I give the edge to the Thunder Tiger
in power. Also, I have @65 flights on my Pro .46 and have yet to
have a single dead stick. None of the OS .46 SF's that I had were
that reliable, and I haven't seen a Super Tigre match that yet, but it
wouldn't suprise me if I did.
Also, a Thunder Tiger Pro .61 runs about $150, so I don't think you'll
be saving any money over the Super Tigre.

Paul,
Ok. Let's see if I've got it straight now. The "Republic of China" is
mainland China, aka "Communist China". Taiwan is simply Taiwan, (which was
the OLD "Republic of China"?) located on an island (Formosa?) off the
coast of mainland China.
If I've finally gotten the nomenclature sorted out, my point is that the
distinction seems to make a very big difference to people in that part of
the world. I think it's important that we realize that Taiwan and China
are not the same thing. Thunder Tiger products are made in Taiwan. I think
ASP and some others are made in mainland China. Am I now correct?

also know there are engines on the market that are better quality then
ASP. ASP engines are like Ford cars they are not JAG'S. But in defence
of the ASP engines they cost at times 50% less then the JAG's. The idea
behind ASP engines is to give the moddelers a good running engine at a
good price. ASP and ISC have been making improvements to increase the
performance and reliability of the engines. ASP and ISC have just
increase the warranty of the ASP engines to 2 years. ASP does have ASP
engines in their best interest. The factory has just installed a second
new CNC machine. This is the second CNC machine installed in 9 months.
My comparison of ASP engines to Super Tigre engines is not some marketing
B.S. I have used Super Tigre engines for years. I am a collector of ST
60 blue heads. I make it a point to keep tabs on the other guys. The
bottom line is that most glow engines of equal size are close in
performance. ASP 61, Super Tigre 61, OS 61, FOX 61, Magnum 61 etc. It
comes down to the individual budget, service and looks. I think you would
agree that a pretty plane always flys faster then an ugly plane <G>.
I feel that ASP engines are a good choice for modelers in the market for a
new engine. I stand by them because I use them and I know what thay can
do. My father and I spend many sundays doing product development so we
can answer questions that maybe asked by the modelers. We also take the
suggestions that we get to the ASP factory for evaluation.
As to my proof if ASP is better then Super Tigre, All I have is just
experiance. And that tells me that Super Tigre is a prettier engine and
it cost more then the ASP.
Test: I had a chipmunk which I tried the ASP and ST 61 engines and I got
the same flying performance and a 300 difference in RPM.(What this means I
do not know) As I stated before "They (ASP) compare well to the ST 61 .

Considering the amount of R/C products that come from that part of the
world, I think it is relevant to R/C. I've heard people refer to Thunder
Tiger products as "Chinese" which really isn't wrong, but I've also heard
people refer to ASP and similar products as "Taiwanese" which is
definitely wrong. Considering the vast differences between Taiwan and
Mainland China, polically and economically, over the past 40 years, I
think the difference is one worth keeping in mind. It may be prejudice on
my part, but my perception is that Taiwan has a significant lead over
mainland China when it comes to engineering, manufacturing and marketing.

Correct, in my humble opinion. But stay tuned. The Chinese learn fast
when driven by economics, and are fierce competetors. In a very short
time the quality of the Chinese products will be as good as the
Taiwanese and even the Japanese stuff.
Sadly, (except for Nelson) the USA is not in the picture.

Geez John, sounds like ASP missed the boat here, perhaps they should
market their products as over-priced, multi-purpose hobby tools! One
question: how do you contain the flying cigarette butts when you use
it as a hammer? ;) ROFL

To call an ASP a piece of junk is an insult to junk everywhere. But

"Bad" Engines out there. And if you want to get the ASP running

he has had many of the negative ASP Engines brought back and

have to break the engine in on a stand. 2. and these engines were
set for F.A.I. -no nitro- they will run good on 10% and add Bakers
AAA Castor to a gallon of fuel or use K&B Fuel. George has been
one of the best engine guys around and has stated that with the

They must be broken in to run-and there are many that have them

operate a two cycle engine. ASP's run great if they are treated well and
are operated by someone that knows how to set up a model engine. Unlike
OS engines, ASP's are not set up for idle and top end at the factory so
you need to set them when you get them. Most of you can't do this and
burn up a perfectly good engine and then badmouth the manufacturer.
I spend at least half my day at the flying field setting up engines for
guys like you who have big mouths and little brains. I run OS, ASP, Royal,
Thundertiger, Supertiger, Rossi etc. ...even Nelsons and get them all
running beautifully because I put the time in to setting them up properly
and treating them well. I also get more power out of engines than most
guys for the same reasons.
So instead of bitching at a hunk of metal take the time to learn how to
operate them and you will enjoy this hobby more, spend less and like me be
the envy of all your buddies.

a
bad OS once....
I agree with you...partly...about the ASP's. Only beef is the carb is a
little hard
to set for good Idle /mid/ and high. And a little tendency to suddenly die
while
leaning out....even though it still sounds rich. But they will run fair
with a little
careful tweaking. Don't own one, don't know how long they last.
Like you, I find myself helping out with engines. I can either set them
properly
or at least point out something wrong with the engine that the owner needs
to
get fixed.
But...If you can make a Royal .46 LS run satisfactorily you are my
superior!
Was the Royal you made run the dreaded .46? If so, tell me how you did it!
Myself and 2 other guys vowed to never touch one again.... I put mine to
death under a large hammer. It felt good. <grin>

will take them one hell of a long time to catch up to either Tiawan
(Thunder Tiger) or Japan (OS / SAITO / ENYA etc). You see they don't have
this funny "gweilo" phrase of "quality control" in their alphabet.
In Hong Kong all the local guy's use mainly Thunder Tiger ( designed by
some guy who used to be with OS ) , and their quality , longevity and
performance seem to come a close match to Japanese engines .
ASP/SC are "C**p" and will be for some time . You now see very few in the
shops in Hong Kong.

OS engines are not set up at the factory for either idle or top end.
How would OS or any other manufacturer know what fuel, prop, glow plug,
etc. you're going to use? How would they know at what altitude and with
what weather conditions you're going to use this motor? Why would they
bother with listing break-in settings in the instructions? Why have
instructions at all? I have never seen any engine manufacturer sell
factory set engines where all you had to do is fuel and fly.
I too have used and worked on a variety of motors from various
manufacturers in my 25 years of R/C modeling. I've seen a lot of good
engines, a few outstanding engines, and a few duds. I have no problem
setting up engines and I also help a number of other people as well. What
I have observed is that most often what seems to be an engine problem has
little to do with the engine itself and is often a problem with a glow
plug, fuel, fuel tank position, etc., but there are rare times when an
engine will not work properly no matter what is tried.
As for most us not knowing how to set up an engine, I beg to differ.
The vast majority of the people I see (and our club has over 260 members)
have very little in the way of real problems with engines. They use good
equipment and have good results. When someone asks me what equipment is
good I tell them to go to the field and look at what guys are using. If a
lot of people are using something there has to be a reason. Very little
spreads faster through a club than word of a bad product.
If ASP engines are such good engines at such good prices why don't I
ever see more than one or two of them at the field? And where are they on
the contest circuit? I didn't see one at the 8 contests I entered last
year. And why are there so many negative comments about them posted here?
Am I to believe that all those people who have had problems with ASP
engines are raging pinheads with " big mouths and little brains " who
don't know how to run glow engines? I don't think so! As for the comment
" Most of you can't do this and burn up a perfectly good engine ..." I can
only say that it is hard to burn up an engine that won't start because of
an air leak in the carb.
I'm sure that there are people who have ASP engines that run alright
and that are happy with them just as there are people who have had
problems with them. The ratio of satisfied users to dissatisfied ones
should be a factor in judging any product, while remembering that some
unhappy users may not be using the product properly, just as some
satisfied users may be so only because they haven' t tried anything
better.
One last thought. One thing I see over and over again in messages
concerning ASP as well as a number of other products is the quote: " You
get what you pay for ". I would like to propose a slightly modified
version that I think may be more to the point: " You may not always get
what you pay for, but you will almost never get more than you pay for ".

particular subject matter and especially to Mr SCOMCA (who I presume is
either a non-deplume or has a vested interest in the subject matter).
Whilst I'm not in the buisness of degrading any particular brand name ,
the comment I have stated regarding the quality control of the production
of these engines bares testiment to the age old adage ;- "you get what you
pay for".
I wish to point out that I have had 3 ASP engines over the past couple of
years and from my experience enough is enough!
Reasons :- Bearings collapse at approx 35 hours , difficult to tune etc.
I wish to point out that if you were to remove the "high-speed" needle and
look at it with the light behind it , you wiil see what I am getting at!
Do the same with an OS/TT or any other , you will note a marked difference
in the manufacturing tolerences ie quality control.
For anyone who has problems with tuning your ASP's then there are four
alternatives:-
1:-Replace the carburetor with an OS carb
2:-Remove the needle and dress the point in a lathe to give improved
tuning (alternatively in a drill and use a fine file/rasp)
3:-Call Mr SCOMCA.
4:-Do what I did.
I wish to also point out that these are not just my views alone , but are
shared by most if not all the RC fraternity in Hong Kong!!
I am sure that givern time the manufacturer will improve the quality of
this product,indeed they will have to as there is plenty of competition at
comparative prices .

I did get a bad ASP engine. Had all kinds of trouble with it. So much so that I sent it back to
the company to get it repaired properly. After trying the engine out, I found that it would not
hold a decent throttle setting; it would lean out terribly in lfight after the first 3 minutes
were done on a given flight. Then after landing the engine would not quit even though the barrel
in the carburator was completely closed!! I sent it back to the servicing department to see what
they could do, and their idea of fixing it was to put some type of glue in the idle adjestmnent
screw, which helped for a couple of flights, but when it broke down the engine caused the same
problems again!!! I am not happy with the ASP engines because of this.
Incedently, I had a Royal 40 which worked very well; had no problem setting it up and it had a
fair amount of power in my Smith Mini Plane with a Tatone pitts muffler. I gave it to a freind
of mine and he used it happilly until he drilled his plane into the ground (hate it when that
happens). I also had a Royal 25 that worked fairly well too. Never had as many problems with
other engines as I did with the ASP though.

Robbie,
Problem is, when a fella gets spoiled on a "ready to run out of the box"
engine,
he may no longer be happy with one that needs more careful dial-in and
running
conditions. No rap against K&B, just a difference in what people are happy
with.
In todays hectic world, many people only have a few precious hours a month
to fly. And they want to spend that time flying. These days there are not
as many
modelers as knowledgable about engines as there used to be. And they want
an
engine that runs like the family car: Just put gas in it and GO!
Some of us are missing out on a lot of fun tweaking these wonderful little
engines.

Modelers are very different in their tolerance for engine problems. I have
heard
folks declare that their brand X engine is the best, as they are walking to
pick up
a dead stick. Others say their brand Y is great if you smear hucky-puck
around
the carb. Or drain their starter battery trying to crank their beloved
brand Z....
Others will not tolerate dead sticks, broken muffler bolts, or sensitive
needling
at all, and immediately declare those engines "junk".
One man's trash can be another man's treasure....

As far as spending time goes, with this particular line of

I currently am using both a K&B Sporter 65 and an ASP 61 to two of my
planes. Although, the initial setup was quite different for the two
engines, they both perform well. Both engines have two season of flying
on them and both appear to be a strong today as when they were new. It
has been my experience that those who complain about an engine
performance are usually the ones who expect to bolt the engine on the
motor mount and go flying without any concern to proper break-in and
carb adjustment. All engine manufactures ship an occasional defective
engine. Example: A fellow modeler purchased an OS 70 four stroke. He
could not get it to run. Finally, he returned to the dealer who open
the back plate and found the inside to be fill with steel shavings. The
engine was returned to Great Planes and they replaced it.

Another good reason to thoroughly inspect (and clean) your engine
before it ever sees any glow fuel... You can flush out the cylinder
head via the glow plug hole, removing the backplate is a just a few
bolts. Washing out any shavings before you start the engine and then
gently breaking the engine in, will solve a lot of problems before
they happen. I did this to my OS 60 FP, and it runs great! I also
had the peace of mind of knowing that I had double checked everything
before I ever fired up the engine.

I read one comment about ASP and CNC machining. It is my understanding,
that they are not using CNC maching in their manufacturing process.
Now, that said, I have been using the following ASP's for several years
with no unusual problems: ASP .32, .40, .61, .75, .91, 1.08
The .40 and .61 have both been run with tuned pipes, the .32 with a
mousse can, and without. I've used a variety of mufflers on all.
The one problem I've found common to all of them is air leakage around the
"O" ring on the high speed needle. This has been corrected by removing
the clip that is supposed to keep the needle from turning and loosing it's
setting (it doesn't work very well), and slipping a piece of silicon fuel
tubing over the needle and over the collet it screws into. This does two
things, it provides the needed air seal, and holds the needle setting.
I have used Byron's 10% Premium fuel almost exclusively, except for the
.32 in which I usually run 20% nitro. I have read recommendations to use
nothing over 5% in the .91 and 1.08.
Yes I've replaced bearings , but I live in an area of high humidity and
expect to have to do this periodically. (bearings rust in this
environment, even with the application of afterrun) I've had to do the
same with my O.S.'s and Rossi's.
I will be the first to admit to you that the casting and some machining is
not on par with O.S. or Super Tigre, but then I didn't expect it for the
price I paid. It has been said, you get what you paid for. In this case
I have, I paid for an engine that runs and they do.
There are others in my club who also have ASP's, and they all are
satisfied with them, except for one who has never had any "luck" with any
engine (O.S., K&B, Super Tigre, etc.) I think you get my point.
