I have the following Nitro Engines for sale. Both were obtained in a trade so I have never run them. Both Have good compression and appears to be in good shape:

Novo C12 has a pilot shaft, side exhaust & slide carb & comes $75 shipped
with a Nova .12/C1 pipe

OS .12 CVR has a short shaft, side exhaust & Rotary Carb $55 shipped
