I've had an ME-109, a P-47, and, a FW 190 for years from HOB.....I guess I will have to build them one of these days. I use my Cox TD .049 R/C on a lot of planes and saw a ME 109 with 2 channels and that motor fly a few years ago and the TD pulled it around as good as the Enya .09 Powerful little motor. I suppose with 4 channels it might take the .09 propped correctly. From what I hear, the FW and the P 47 are the rare ones. I'll get to them someday!!
