Wheels turn while idealing

[brad55102]

I'm breaking in my first nitro, just running it on the bench and while in neutral the wheels turn and i can't stop them. I tried adjusting everything but short of applying the brake i can't stop the wheels from turning. Is this normal? What should i do?

 

[grgbulldog]

did you lower the idle a little? it could also be the throttle trim on the radio. unless you've tried them, i dont know what to say

Check your idle needle and your low speed needle.

 

[grgbulldog]

low speed! thats what i forgot

Check you clutch too. you may have a ruined spring or seized bearings.

Broken clutch spring is a common problem. 5 min fix.

When I had the same problem it was because I didn't have the low speed needle tuned correctly.

During break-in, engines run pretty erratically. It may smooth out the more fuel you run through it and accept your needle adjustments better.

Just something to keep in mind.
