Suggestions? I need a fast plane for a rear exhaust YS 60
Hi,
A Kaos wouldn't be "Really Fast" with a Jett 90 on it, much less a 60. The wing is too thick.
The approach I would take to go fast with a YS 60 FR (excellent engine) would be;
1) Select an ARF Q500 that gives you the flexibility of mounting locations for the fuel tank, battery and servos. Another good thing about the YS is it doesn't care where you put the fuel tank. This will give you the ability to balance the YS with plane designed for a 40.
2) Raise the exhaust port .030", Mount Macs#1160 Pipe at 16.5" (Glow Plug to end of converging cone) Use APC 10X10 cut to 9.25", Use 25% Fuel, Expect about 16K on the ground and a serious RPM increase in the air. HANG ON!!!!
