venture30 engine tuning/upgrade
need help please on my Venture 30. Coming from a plane flier new to heli's, whats easiest way to tune engine. (Cant exactly full throttle & hold the sucker nose up like i'm used to with planes!). keeps cutting although running fine(but hot), lots of smoke. Using 10 -15 % nitro,synthetic fuel. os 8 plug.
Also is there a larger motor that will bolt in with min. mods.? Think this one may be tired.
Appreciate any feedback
