hi there
i have a thunder tiger pro 70h engine that has been a real pig to tune it is fitted with the standard tt pipe,the tick over is up and down and not very sweet and to keep the heli flying i have to run over rich or it will just go lean, i have used cool medium and medium hot o.s plugs and it is the same with all the plugs fuel has been opti 20% and rapicon 20% could it be the tt pipe is not letting the motor breath also what is the default setting on the low end needle,the motor and pipe were both new and have now had 8 lt of fuel through it i will soon have pulled all my hair out over this little devil :evil:
