I haven't flown any warbirds yet, or micros. I have a Ultramicro Pole Cat, and I ripped out the original micro receiver/esc and put an HK one, but not the battery wire isn't long enough. I had a Durafly Spitfire, but after snapping the prop, and then listening to my LHS about a 2 blade that wasn't enough for the plane, it crashed. I found a better prop, but I gather a servo was damaged in for the rudder, causing a propelled flight into the ground. The Mountain Models P51 will be first warbird that I hope will fly, but I too am waiting for retracts, and spring. How do you like the PZ FW190. I don't like the looks of the PZ Spitfire, it doesn't look near as good as my Durafly did, but the FW190 looks great.
