| Look forward to reading the rest of the thread. You should come by the shop. The 50 is 95% ready and the 70/90 not to far behind since they use a similar design just different motor mount, bell, pinion, and tail boom diameter and length. We are hoping the 70 will weigh around 9 lbs not much over. So the 90 would only weigh a little more due to motor weight. We will have to see once the machine is built up and on a scale though. The power would be unreal if we had a 70 weighing 9lbs. Wouldn't need a 90. We would get good gas milage and the motor wouldn't cost that much either. I think 90 sized motors are over priced.
And since they are similar designs, you can put a 70 in the 50 as a big block option for crazy power or if you live at high altitude. Or if you just want to upgrade to a large bird down the road. To convert the machine you would only need new lower frames, motor mount, clutch stack, clutch bell, boom clamp, and boom and belt or TT. The 50 uses a 21mm boom and 70/90 a 24mm boom.
