I am building a Super Skybolt ARF. I mix it up with my Midwest Extra kit. The Extra gets priority. I am in no hurry. It is so pleasant this way. Here are the specs on my Skybolt: Saito 91, Futaba 9001's all around except throttle which is a Hitec 81. Battery - Fromeco 2600 mAh LiPo regulated to 6.0V with a MAXX products miracle switch. The first two pictures show the Extra which is slowly but surely coming together. Back to the Skybolt - I plan on fitting a DuBro tank instead of the one that came with the Skybolt. It is almost the same size, and I prefer having a cap which surrounds the opening at the front of the tank. I am nervous of the ARF tank splitting over time. If you look carefully at the wing joiner, there is an 1/8" dowel near the tip. There is one at the other end too. This held the two pieces in alignment as I laminated them together with epoxy. No worries about sliding out of alignment. One more thing - I will mount the engine inverted and use an Electrodynamics on-board glow system with a 3400 mAh single NiMh cell. I'll run a flexible exhaust header.
