I have just got my escapade back and have a 55ax with jett muffler, I have not been able to maiden it yet as the battery I choose was too large to fit in the fuselage but I would highly suggest the 55ax and a jett muffler, you will NOT be unhappy, the new RC news has the flight test of the escapade and is running a 46ax and they said they barley needed half throttle, so with the 55 ax you will more than enough power on hand if you need it, I propped mine for speed, with a 10x8 the new battery is in and I am breaking in the engine, just waiting for another nice day since its gotten cold her in chicago. VERY VERY well built plane, very flawless. Very solid and the gear is much more sturdy than my pulse 40. With a 55ax the escapade is going to haul ass. Throw on a jett and youll have more than enough power for practically anything. Glad you chose the escapade. 100$ how can you beat it? You cant......
