I agree with jucava. I'm building a skybolt now and this is the best kit I've ever done. The plans/instructions are very detailed and easy to understand. Unlike most other bipes out there, the skybolt has "curves". Not really an square edge on it. Very sexy

. It is also my first bipe so I was glad to see it modeled in realflight G3, so I could practice on the simulator while I build. Can't say enough good things about it. Hope this helps.
Final Note: With bipes, smoke systems and 4 stroke should be standard.
