df6 will not accelerate

[ktomasz]

My motor runs well only on low revs. When I increase the revs engine responses great and works smoothly but the prop will not turn any faster…??Gear box problem?

same here, at low speads it rund fun, good prop output.

At high rpm, the prop spins.

So i put it on the bench and can turn the prop when in gear, that should not happen.

I ordered a new prop today, will see if that fixes it. I see no sheer pin to replace in this design.

Yep you have a spun prop. See my other thread on the subject.
