I have the combo and am looking at whether I should use the pitts muffler or the standard one... Are you guys gonna put a pump on it? I am wondering whether it will need it if the tank is right behind the firewall. I plan on trying to 3d with it. I have the blue one waiting at the LHS Putting 545s in the wings and 645s in the tail, 545s same price as the 225s and have have 5 pole motors.
