RE: Spot On 50 Build log.
Final update....
The carbon gear from Hoby City was swept back a bit too far and made take offs and landing on tall grass difficult as the plane would usually nose over. I found the perfect replacement in the3DHobbyshop 55" Edge gear. It's even lighter than the hobby city gear.
The performance with the 12-6 was not very good either so we went back to 12-5. I think we originally ran the engine too lean so this time it was set just 3-4 clicks in from very rich (4-cycling) and tached at 12.2K. At that setting the plane has very good vertical performance, slow downlines and good speed.
I took a little right thrust out and added 5gms to the left wing. Uplines are now very straight, loops need almost no rudder.
Rolling is very axial with 0 differential, snaps are super fast but are bit too deep....we are going to reduce the aileron and elevator to fix that.
The overall performance is exceptional for a 50 size pattern plane.
