sorry about your loss im not here to say you glued what to what or didn't glue what to what.
as rc flying goes airplanes get retired or wind up in the trash.
i am not a crash fan but they happen
with that in mind a wing failure in flight makes a great crash.

go out with a flash of glory looks like that is exactly what you did

keep flying have fun everyone

Hi David,

That's pretty much the same temperature range that I fly in during the summer. I'm also roughly at sea level. If you are still having over-heating problems after you increase the cooling air exit area at the rear of the cowl around the nose gear, try flying with a little richer fuel mixture. Max out the RPM's on the ground and then richen the mixture until the RPMs drop by a 200. See if that solves your problem. What nitro content are you using? I have used 10% and 15% with good success.

-Eric

well guys finally flew the lancair on sunday

made 3 flights all of them went well great landings a bit bumpy the last oone but no problems
made some slow loops and rolls the engine did not quit eventhough the air temp was 32 degrees celcius
it tended to climb but some down elevator fixed that it is balanced a bit heavier on the nose so i guess is just elevator positioning problem
the landing gear work fine did not bend or anything of the sort,
flys strait and true and lands perfectly evethough it takes a long run on the tarmac for it to stop

any way great flying soon videos at www.cybul.com/rcguide.html

regards

Default Thank you

12 years later I bring this thread back to life!

Recently picked up a never used GP Lancair ES 60. It was in storage for many years. Had some hangar rash to touch up, but overall in very nice condition.

Found this old thread and the info on the weak wing joint. I have stripped the covering on the wing center section, added an aluminum wing halve joiner (epoxied/screwed) and then attached the 2 piece landing gear to this joiner. Then I added 4" wide fiberglass around the entire wing center (including the aluminum joiner), section. I hope that this mod, along with flying the aircraft in a scale fashion (not high G aerobatics), will be sufficient to enjoy this beautiful bird for a long time!

I've also replaced the nose gear.

Thank you to the OP for the info, and for the helpful comments on how to correct this design flaw. Appreciated.

It's powered by a Tower .75.

Anyone still flying this plane?

Anyone? anyone? Bueller? Bueller?

Default Found one turned into my local hobby shop.

I recently found one and am considering electrifying it. Will cut out and hinge the door so I can add batteries. Looking at a Power 90 motor for this bird. Will reinforce the wings if I do buy it

I have had three of these Lancairs , all with the same Super Tigre .75 in them. The first had many flights , and a few "hard landings" , and finally cracked the fuse. so bad that I decided to replace it. The second had about 35 flights on it when I put it in from an inverted flat spin. The third and present one has about 15 flights on it ,I am kinda babying it as there are not many around. Still have the wings of the two first planes.The tips are cracked and gear broken out but no problems with join. All three were glassed on assembly,on the last I added some carbon fiber strips out past the gear cutouts. I might add that I flew all of these pretty hard. I do like this plane and it really impresses coming down in a knife edge spin.

I have a NIB coming in the mail. Planning on an electric conversion. Probably 8s or 10s. Not sure what motor.

I am thinking about fabricating an aluminum wing joiner and landing gear brace.
