Thanks everyone

the plane is a Hangar 9 Funtana X 50.
i am trying to get the most pull not speed.
i'd rather have it nearly torque roll than make it a racer


i have put a 2cm exhaust deflector.
Will taking it off have an impact on power???


Can anyone give me the BEST motor(OS 46 AX)---prop combo for this airframe to get as much torque(vertical performance)??

How much does the percentage of NITRO added to the fuel affect the power??
What is the max. Nitro %%% i can put into the fuel???
Will to much nitro damage the engine??

is a hot glow plug better than a cold???

THANKS
