The Rotormast V-22, sold and developed by Tom Mast has been on the market for some time now, and has gone through a few updates over the years. The kit is a builders kit and anyone who enjoys building would enjoy this build. Attention to details is quilt important on this one, as any missed step could result in disaster, and its easy to overlook some thing. Tom has several videos out on the construction process and he's done a good job on explaining things throughout the videos. One of the first steps is building the motor pods. It starts out just like building two 450 helicopters. The parts bags in this kit were not numbered or labeled, so taking your time and identifying what screws and parts go where is important. Here's the first motor pod, with the joiner tube.
