Belt cp cnc main grips on e smart

Maybe something you guys want to truy as a tail grip option.

Had a few miscellanious cnc belt cp parts layin around and thought id tinker. I found that, the belt /trex v1 f-shaft is the same diameter as the bolt for the stock tail grips. The only thing i didnt like about it was the grips were longer so it put the rotor diameter even with the tail fin.

So what i did was cut off the inner bearing area and smoothed it flat to the surface where the ball is mounted. So now the stock hub bolts up to the inside bearing. I also filed about 1-2mm off the stock hub to bring the rotor diameter in just a tad bit more. Find a bolt that gets a good thread amount. I used longer bolts and cut them down to just where they dont hit the tail shaft so i get maxixmum grab. theres still a good amount of meat left on the hub so nothing to treally worry about.. Then just assemble the grip as it would be on the main rotor: bolt, thrust bearing, spacer, inner bearing( grip). I use red loctite because im running 6s and apparently 10,000 rpm is unsafe for a belt drive system like the es's. Just a little bitta extra peice of mind.

seems to be holding up.

took a few pics. Oh yeah, youll also have to put trex size balls on the grips. The esky balls are tiny.

was doing some pretty hard piros today and still slop free so i think there holding up well.

I actually got to thinking about it and there is really actually nothing holding the grip from slipping off the bearing back inwards toward the tail shaft. The centrifugal force holds it obviously the other way. Not like its easy getting thoses bearings out, man is that a pain, i have to break them to get them out. You would have to ram the tail grip staright into a brick wall for that bearing to pop out of there.

thats a cool option for the tail blades, I never would have thought Belt CP main grip would fit

I wanted to take a v2 grip off my head and see how that fir but i couldnt bring myself to dissassemble my perfectly flying 450

yeah, sometimes it really doesn't pay to mess with stuff that ain't broke, lol

maybe ill give a shot now, since i drove my belt into the ground today. And then lost one of my brand new gorilla paddles down the storm drain. Dont forget to take it off idle up if your gunna bail out.
