Jumping Jack - Strange loop performance !
..I call it strange loop performance - when I first flew my new AXI 2808-3S Lipo - Powered Jumping Jack.
The CG is as suggested in the manual at 85mm and the weight is exactly 700g with batt.
The Power is OK, but I'm not able to control a fast narrow looping - beside this the low speed performance is so bad that I'm not able to do a low speed landing -
overall I don't know what this problem causes ?
The delta angle between tail wing and main wing is +1° and seems to be OK !
Can anybody give me a hint to heel my JJ !
Or is this just the way it should fly ?

RE: Jumping Jack - Strange loop performance !
I am not familiar with the plane,but if all your control surfaces are set correctly,and the c of g is correct,I would look at the thrust angle of the motor.It sounds like you may need some down thrust in your mount.Maybe try try shimming it down a few degrees at a time until it starts to behave.
