What a shame, but it looks like a reasonably easy repair from what I can see. I hope it goes well and you get a successful re-maiden.

All the Best.

Awww Lucas, what a shame. I think we all share your pain!

After a crash my first thoughts are to chuck the remains in the bin but I know to resist that urge because a couple of days later I always find myself figuring out how best to execute a repair.

With your building skills it will soon be back in the air.

By the sounds of it the main learning point from all this is that the Gnat needs more elevator movement than the recommended 6mm? My build is close to completion and, with a relaxation in Scotlands lockdown rules now imminent, my maiden flight isn't far off (hopefully!).

All the best with your repair.

Sorry to hear about the mishap, hopefully you can repair it . I also needed a significant amount of up trim but still had sufficient control authority. I decided I had probably been too conservative with the cg and marked it up to move the battery slightly rearwards for subsequent outings. Not got chance to see if there is any difference because the field has been in lockdown ever since and my ‘ home ‘ flying field is too small for such a missile !

Good luck for the next trip.

To John: I think it is too early to conclude that more elevator movement is needed. I have increased it by 15% but maybe more important reduced exponential from 30 to 10%. What do other fly with?

Main learning point for me is that a site with a straight in-out flying path is needed so that an aborted landing can be done by just opening the throttle keeping wings level and pull up after sufficient speed has been reached.

Also trim in 1-2 mm up elevator straight away. At launch you may need a bit of up elevator to prevent a dive before flying speed has been reached.

Hi Lucas... opps on the flight BUT ...take 3 positives the model flys well, the cause of the crash is being unlucky with the site ...and the model looks straightforward to fix

i have had many models like this and it’s the great thing about wood builds with splinters like that🤣. Some wood glue on those splits and a great wetter area . The repair will be stronger that the original . You will soon be back in the air.
Keep it in close, keep the speed in the turns , smooth and wide and enjoy. My favourite by far. Until the baby Hawk is finished

The repair is well underway. I double the damaged former(with holds the battery sidewise). And put a 2mm balsa plate under the area with the small fragments.


Some extra wood to align and top deck:


and glueing everything back together:

All holes were sparkled with light weight car body filler and sanded afterwards. I noticed front and back fuselage have little contact after one cuts the battery hatch. I reinforced the gluejoint in the lower triagle stringers with 1mm ply plates in the air intakes and a piece of 25gr grass over the bottom of the fuse to the air intakes.


Litt paintwork in the cockpit, glue the canopy back on and ready for covering again.

Wow .. fantastic job Lucas... told you the repair would be not too difficult. The beauty of wood models and a great design . It will be great to hear it’s back in the air again
