You may need to remove 1 or 2 springs for it to engage at low RPM and still grab without slipping. The clutches need a nitro RPM range to function correctly. You shouldn't have any trouble getting it to work, but you will need to set it up a little differently.

That said, I really like what you've done with it. Turning the diff around and using the RCM mount will eliminate flex issues so your metal to metal contact should be trouble free. Definitely keep us posted (you too David :).

I think it will be OK. I'll probably just run the .9 or .95 springs if it doesnt grab the way I want with the 1.0 springs. I will be running a 1306kv motor, but it will be running on 5s so it will still get up to 24-25K rpm. It should be fine I hope. If I do run into that as my barrier to making it all work. I can always find a motor with a little higher KV. I have some in the 1500-1600kv range too. I'll for sure keep this updated as I make progress.

Looks really good, I like the RCM mount idea, I may try that on my 8ight because its diff is already facing that way.

Good eye... Yea your right about that. I just put it together for fit up and testing the layout. When I put it together I saw that it needed some adjustment, but I didnt feel like messing with the springs again so I just left it for now. Those clutch springs are a PITA. I'll fix it before running it. It will be a few weeks before I get much time to play with this again and finish it up with the hollidays coming up. I will have people in from out of town and then be traveling for a few weeks fr work. I'll be lucky if I get to it again by late January.
