i built a rappy 50 for my mate, its finished, test flew it earlyer, flys really well, biggest ive flown, just a question on the engine really, i run a few rich tanks, now it needs a tune up, its a redline engine, cant remember which one, its only got 2 needle adjustment, low and high like a rc car, it idles well, just ticks over, climb outs are good abit pokey now, loads of smoke tho (magnum fuel) my question is, normal mode is a 0-100 thottle curve, on a decent the engine screams abit, do i lower my mid point and go 0-20-40-75 100 to even out the revs?
any help wld be great!!
(where the fu** did that pic come from????)
