I think the Vess 22A is a good break in prop. when mine was running , I could at any time put my fingers on the crankcase and it was only warm to the touch. It does not over load the engine and make it get hot. I will fly the 22A but I am going to limit the servo travel to prevent over reving. my main concern presently is the noise and the vibration. At 2500 rpm, it looked like the horizontal stab was going to break off from the vibration. I hope it smoothes up some when it gets some more time on it.
