This is an incredible value for the money. Where else do You find a true Aluminium Bronce Chrome Cylinder/Piston setup in this price range? The motor runs at a power level that is at least equal to that of the OS 25FX. After flying the motor about 20 times I bought another one as a spare. I am so happy with it.

This motor is perfect for anyone who wants a small yet powerful unit. I have used the breaking in procedure as recommended by ASP, the only change i have found is that the starting idle is fine set as 2 full turns out from the tightest piont. I am now running it with a 8x6 three blade prop that produces a ratio of 1gram planer wait to 5grams of thrust that makes my home made model a little screamer in the air.

I have been using 10pcnt nitro that seems to be working with no problems.

timo motor ficou muito bom no aeromodelo escala de 1.84m de envergadura com cerca de 1.9kg com uma hlice 9x5.Sugesto: No utilizar hlices maiores de 10" pois o motor perder o desempenho
