I will be doing this soon With my trex 450 and blade 450 3d. Its usually pretty windy here and flybar-ed helis dont really like the wind. To boot I probably set something up wrong because I am terrible at flying them but I can fly my v450D03 quite easily. I purchased a conversion head off ebay for the TREX and a Tarot head for the blade so i don't have to grind the main shaft. Both are getting KBAR minis. I crashed every time with the blade, never flew the trex after crashing so many times and local parts are not available for the Align. 2 main shafts, flybar, 3 feathering shafts, 2 sets of blades and a set of grips was enough for me to want to swap. My walkera flies beautifully, wind or not. Hoping the other 2 will follow suit lol.
