Thanks
It is the first plane for it, but I bought the engine second hand. The needle is "remote" meaning that it is connected via silicone tube as on the OS FX series. It is possible to connect a servo, but I do not think it is necessary.

I see now that the other prop I have, is 9,1x 12,75. It should be "state of the art" with very thin blades and moulded in special carbon so that the tips doesn´t fly arround my ears [8D]
Price was approx. 20 euro/pcs.
