2 seat Motorglider kit/plans
re...@in-newsgroup.com
Lately i have been bitten by the gliding bug, and am considering building
a motorglider....
I have found many plans and kits for 1 place gliders and motorgliders, but
the 2 seaters in the experimental category seem to be few and far between,
can anyone offer some references or suggestions?
I would be building on a budget, so older kits or build from plans would
be preferred (i/e i cant go plunk $20k+ on a quick build type
kit..)
thanks,
Steve

It's a touring motorglider with 23:1 best L/D, and it seems to be a good
ratio budget/building time.

It is available as plans, kit, finished or anywhere in between.

They both intrigue me, though i am disappointed that the alpaero offering
doesn't have a retractable gear option (i intend to fly it power off as
much as on..)
An idea i had, though it may not be feasable, was to make something like
this:
The kr-1 has a motorglider configuration, the kr-2 does not.
Would it be possible to modify the kr2 to use the kr1 glider wing? or
perhaps modify the kr-2 wing to be larger? (the added benefit to this is i
have a friend with a spare set of kr-2 plans...) though i dont think it
offers a retractable gear option either :(
this is just a thought i had, but my airplane experience is very limited,
any suggestions on good books to introduce me to the nuts and bolts of
aeronautical engineering would be much appreciated...
take care,

the new wing and calculated the new tail volume etc but never proceeded with
it.
The Alpin-8 can be bought ready to fly for about what it would cost to build
a KR2 and has much more performance.
Remember that the KR2 is a squirrelly aircraft to begin with. Many builders
opt to stretch the rear fuselage to give it a little more stability. Not
only is the fuselage short but it is also fat. This tends to blanket the
tail.
To make a glider out of it, you would have to enlarge the fuselage and the
tail and the wings.
Why not look at the Europa motor glider version?

Seems like a much better idea.

When you register it, it is registered either as an airplane or a
glider.
If you are glider rated, but not power rated, you want to register it as
a
glider. Once registered, its class can never be changed.
To qualify as a self launched glider, the span loading ( weight / ( span
squared ) )
can not be above .62 pounds / square foot.
There is also a weight limitation of 1874 pounds, and a two seat limit.
The Europa is close, and they are supposedly makeing some design changes
to bring it
within limits.

Is the homebuilt limitation so much different then other self-launching
sailplanes. For example:
PIK-20E (single place)
Wing area 107
Empty Weight 684
Max Gross 1036lbs creates a wing loading of 9.2lb/square foot
Nimbus 5DM (two place)
Wing Area 181.4
Empty Weight 1268
Max Gross 1764 creates a wing loading of 9.11 lbs/square foot
Schleicher ASH-16E
Wing Area 125.94
Empty Weight 935
Max Gross 1289 for a wing loading of 10.24
Stemme S 10
Wing Area 201.7
Empty 1400 lbs
Max Gross 1874 lbs. for a wing loading of 9.29
All of these are classified as motor gliders. What am I missing?

After taking a second look I realized that the regulation is not talking
about wingloading. Doing the span squared calculation gives the PIK-20 a
value of 0.4144 and the big bird Stemme S-10 a value of 0.33.
I guess I should read the post before I jump in!
