The adapter is just a shaft like a nitro engine output shaft that goes on the motor shaft with a set screw like apinion gear. You can mount whatever traxxas compatable flywheel you want on it. Mine happens to be 3 pin/shoe style clutch from M2C, but a standard Revo 2 pin/shoe flywheel also works. Mike sells a small diameter 2 shoe traxxas flywheel for this made to work in this type of application.
As far as the cogging... The Tekno RC revo conversion uses this setup with a MM and a Neu in a Revo and they have poven it to make a the cogging issue a non-factor. But to me I still wish Castle would fix thMM software. They have been saying they will ever since the MM was released. Typical CC... All talk and no action.
I like the push/pull idea IBJammin... I did think of pushing one side and pulling the other but not in that simple config. I didnt go the push pull route cuz I was hesitant to try pushing one of those skinny little rods. I wasnt sure if it would be consistant.
I will probably stick with this setup cuz its done already and it seems to work pretty well. I have 4x7 bearings in the middle of the cam lever riding on a 4mm screw and it is very smooth. When I disconnect the linkages and spin the lever it spinns like a wheel with very little drag so I dont feel like I'm loosing much energy in the mechanics. Although your idea would probably be more efficiant even if its just a little. I'll make that plan B. If this doesnt work out. It would be an easy change to make. Thanks for the sugestion
