Review by: FTJust get it! You won't regret.
Has been waiting for almost 3 months. Once I got the notification that the plane is back in stock I had order it immediately. The plane itself looks perfectly made and perfect finish. All of the parts you need is included. I also had order the recommended servo from Blue Bird. I still have to start building it and hopefully will maiden soon. Big thanks to Neil for a perfect customer service!
Review by: ChrisJust what I wanted!
After reading other reviews have gone for a lightweight set up: 2207 2750kv quad motor, 45a Speedix ESC, 4 cell 1100mah lipo and 4.74x4.75 APC prop. Radar gunned at 145mph. Exactly the sort of speed I was looking for without too much outlay. Relatively easy build with lipo up front to achieve stated c of g without additional weight. Be careful with elevator control horn: too short.
All in all very pleased.

Unlike the Voodoo this model takes some time and care to set up but once done the rewards are there; the longer wingspan gives a broad scope of ability; a very light setup can glide off power for a while; launches and landings are very stable and predictable. Initially using a conventional inboard motor plus 38mm spinner I was unable to achieve absolute zero vibration throughout the whole rev range. After some research I decided to try something radically different and installed a Hypetrain 2207 Acro motor outboard of the firewall. Weighing a little over 30g but capable of producing around 2kg thrust, this quad motor is a revelation. With a balanced prop there is zero vibration throughout the whole rev range. Even with a light weight first run setup, speed is excellent, using a 2450Kv motor running a 5.5x4.5 prop. With a 1900Ah 3 cell pack I got around 8 minutes of mixed flying which could have easily been 10 minutes with more climbing and gliding.
