Folks,
For those of you have not assemble the kit.
Take little time to modify the stab.
I open up my stab to inspect the work. There is no spar go across the stab. The stab possible can fail when flying fast.
Here how I would do to reinforcement the stab. Make 2 spars out of of 1/8" liteply. Cut little slot to insert the spar. Clue with CA or expoxy. Make sure the spar just firmly fit. Not to wide or to narrow. You want the spar to touch both side of the skin.
If you guys already assemble kit. Cut the slot from the bottom to put int the spars. Fill up with aeropoxy and sand it level. Cover with mono coat or painted over to hide the work. Do the same to the fin.
I'll post some pictures of the mod very soon. I stongly recomended everyone to this.
Also strenthen the main former with carbon fiber. Ther gear box also need to reinforcement.
This is very nice flying trainer. It just need some modification to handle the stress.


Also keep this bird under 150mph. My fly with 12lb thrust engine and got the smoke system onboard. My can fly over 150mph if I really pushing it.
This plane is not bullet proof. Put in the speed limiter to kept it from flying over 150mph.

I'll kept you guys posted.
Tam
