Can someone give me some advice on tunin my engine, as soon as i set the low side, increase throttle, right about mid stick it starts to get sputtery, so I leaned it out got to run smooth but now my head speed is way high, to get down I may have to go as low as 30-35% at mid stick (shooting for about 1550rpms) This doesnt seem right. Please help.

We might have a better chance of helping if we knew what engine, muffler, fuel, and glow plug you are using. Just trying to help.

The government cannot give you anything without first taking it from someone else.

At least your engine is running properly now

Check you pitch (and throttle) curve
You don't go down by decreasing headspeed, but by decreasing collective pitch.

Check Raptortechnique.com, they will dispense very interesting information on curve settings.


Moreover, check that the run of your carburator arm is linear. (when we say 40% of throttle, it's not 40% of servo travel, it's 40% of carb operture. (and the throttle servo should also be @40%travel ))

Thanks alot guys for the info, I know sometimes I dont respond right away with a thanks. I dont mean 2 be rude, it just takes me awhile to try the tip youve given and then get back to u, I really appreciate all the help. It has been difficult, learning with very little or no help, especially being in South KOrea and very few people who speak English into the hobby.
