Well, by what Wayne Trivan did, he was a big advocate of turning less mass, check out his prop balancer, I did the same mods and wow that works, so I figgure the same principle works on any rotating part, less mass means less power to keep it spinning, more mass would help in the tourque game though. For my purposes, I like the rpm game, and the light crank by itself paid me back bigtime. In the norvel, I think it is a 50-50 deal between mass and friction relief.
I scrapped the case I was machining last night [] Doh!
I have been pondering the "perky" event along with 1/2a proto...too
I will post some pics on the new case I will start tonight for my 1/2a r/c pylon.....still devestated about scrapping the first one.. I did the age old mistake, mis-read the mic .100 and cut that baby....no way to put material back on. My heart fell to the floor, I had over 6hrs into it on the mill. Its kinda hard to do. second time shouldnt take so long though I hope.
