Yes its my understanding that when they were designed the glow 60 was the biggest motor commonly available. I believe most of the nosen designs were based on build light fly underpowered ! Although the light part was always easier said than done !

I am curious as to if a good 25cc weedwacker conversion would fly it or not? I am sure something in the 30cc range would be much better. Hopefully we can get a few guys to share past memories of what they have seen.
