I guess Ishould have stated above...

I had problems with the engine sagging after about half the tank was used up. Violent maneuvers would cause the engine to lean and quit too. And it leaned and sagged during inverted flight...


The above mod, along with the needle twekaing required because of it seems to have fixed the problem entirely.... saving me the $60 for a Cline just now....

I may still move my tank to cg and add the Cline, but this mod fixes the inherent design flaw of too high a tank in an inverted engine mounting design...

Hey Great Planes!!! Take note...

1) Stronger or better yet carbon fiber gear
2) Beef up the wing/gear former than seevral have had go out... maybe bump it up to a 1/4" part
3) swap positions of thsat cross brace to allow the tank to set on the bottom of the former... not the top... (and move the tank opening in the firewall accordingly)
