Interested in any feedback from those experienced with this kit and/or
plane!

Robbie,
I have built one of these kits, and have flown several others. You will
be happy with it for the money. It is a nice flying plane- very forgiving
yet will fly impressive aerobatics.
Keeping it light is definitely the key. I'm not sure why the reveiw model
came out at 26lbs. Keeping it at 20-22lbs should not be any trouble. I
reccommend getting rid of plastic turtledeck and wing cover (canopy). You
can get replacement parts from Bob Godfrey's Precision Aviation. Also
does not hurt to replace cowl and wheelpants for fiberglass.
My Dad has one of these with a Q75. Mine had a G62. The extra power of
the Q75 definitely makes the plane come to life. Even if you get it in
close to 20 lbs, there's still a lot of plane to whip around!
You should check out the IMAC web page at:
Under the kit reviews is an aritcle about this plane.
Good luck!

My partner has one of these and originally flew it with a D&B 3.7 twin. It
was a bit heavy at 24 lbs but was still an impressive "tumble-batics" type
plane. A real floater and did quick snaps, but the vertical climb was not
unlimited. After installing a D&B 5.1 twin and removing some unnecessary
weight (gyro and battery) the plane remained at 24 lbs. It now sparkles
and has visibility as it's only vertical limit. He does a vertical climb
on takoff with snaps, rolls, and tumbles on the way up to the limit of
sight. Impressive plane, and an impressive engine. Ken Baker did his
usual fine job on this engine design.
62 cc engines will power it fine, just expect the vertical climb to be a
little limited. Choosing the best prop for this will take a little experi-
mentation. You should be able to attain 22 lbs by using film covering and
watching hardware weights. You'll love the way the plane flys when properly
set up. Follow Bubba Spivey's recomendations for control throws and cg
placement. Fly it and get used to it before moving the cg backwards a little
at the time.

Robbie,
It is a great flying plane, no matter what the weight. A G-62 is the
reccomended engine due to popularity and ease of getting it. The one's
we build weigh about 18-19 lb (yes that is correct). The planes in
question were in the latest Lanier ad in Model Aviation. The Black
Laser weighs 18 lb with smoke, and the white/blue one weighs 19. No
special building techniques were used except for taking care in using
epoxy (none on fuse except for firewall), and vac bagging the wing. I
have seen many that weigh 23-24 lb that still fly great. The biggest
savings is through the wings.
Send me some e-mail for any info about how to bag them, also we do bag
wings for hire if you are interested.

I personally don't have a problem with the plastic parts on the lanier
planes, you just need to take care in assembling them. Any place you have
a hole, or cut and opening, you just need to put some light glass on the
edges, and glue it with ABS cement and not CA. The abs cement (plumbing
dept @ Home Depot) stays flexible enough that the plastic wont crack.
John Helgesen
No can of worms, just a lot of personal opinions. As for mine, I agree
with you. ABS plastic has it's flaws, but it also has great
advantages. First, it is lightweight. Second, it is easialy finished.
Third, it is pre-formed (i.e. easy to make). And finaly, Lanier's ABS
is even trimmed (cowl) and marked (hatches/turtledeck) for a good easy
fit.
Now ABS does have disadvantages... First, it is not very vibration
resistany, especially around screws. Second, some paints will deform
the plastic. And lastly, heat (i.e. engine and sun) can deform the
plastic.
My only response is to do exactly what you did. Reienforce the screw
holes with fiberglass. Also, a trick that I learned was to use the ABS
to produce fiberglass parts from. On the Laser, we make a glass part
out of the canopy hatch because it is removed often. On all my other
Lanier kits I use standard ABS parts.

My Zenoa G62 in the same plane would not be able to keep up with it in
the Air..

I own both a Brison 4.2 (well actually 2 of them) and a G62. The
G62 is about 30% less powerful than the Brison 4.2. My G62 spins a
22x10 APC at a bit under 7000 RPM but the Brison swings the exact
same prop at close to 8000 RPM (I actually fly the Brison with a
22x12 APC). A difference of 1000 RPM works out to about a 30%
difference in thrust (roughly).
By the way, you say somebody is swinging a Zinger 24-12 prop
on the Brison? What kind of RPM is he getting? Sounds a bit
loaded down to me but I guess it depends on the muffler you
are using.

Saw a fellow just the other day with one. Awesome flying plane.
He used to run a G62 but it was nowhere near enough power. Now runs
a Bennet 4.2 (B&B specialties) with a Zinger 22x8-14 prop and a
B&B smoke system. It goes like stink can hover all day and I've
seen it takeoff to knife edge no problem. .... by the way, it
weighs 28lbs!
The 3W 60 would probably work well in this plane as it is almost
as powerful as a Sachs 4.2. A friend of mine has a 3W60 and it
turns the same prop only a few hundred RPM less than my Brison
Sachs 4.2.
Cheers,
Just to let everyone know, 28 lbs is the heaviest recorded weight of
this plane yet!! I know that the reccomended weight is 18-22 lb.
Please note, a G-62 flies this plane AWESOME if you keep the weight to a
reasonable amount.
