FlyingGiants - View Single Post - Composite-ARF SuperExtra setup

I need some advise on my Composite-ARF SuperExtra (Carbon Spar) plane as far as mounting the engine:

1) I have 2.5* right thrust, but no up thrust. Should I have 1* of up thrust?

I fly mostly 3D and NO IMAC, so if I have 1* of up Thrust, then when flying inverted, should I move the batts further back, or use the front wing position for balance???

2) In the manual for both my SuperExtra and my 3.3 YAK55SP, should I have 3/4 oz of lead in the leading edge of my elevators for counter-balance?

Thank you for your help!

Best Regards, Mark
