hi, I have one, it is in an ESM Corsair, 85in, only about 1 hour air time on it so far, very happy with it, wish I had bought the one with the on board starter, would look cool, runs very nice, not as quiet as I had hoped, quite smooth, would be great in any model with room for a twin, you will need a good starter to turn it over, as both cylinders fire together, I have one of the belt drive HK starters with a 4 cell lipo, only just winds it over,
so far, a very good engine, good power, smooth. Would recommend it.
