Planning Revo V2, to use stock tranny, C. diff and RCM motor mount

[Serum]

I am curious how much the transmission would weight with the FOC? got a scale Finnster?

I have a very fine digi scale. :) I actually have two trannies, one stock 2.5 and a CD/rear brake (which includes FOC by default.) I'll get some weights tonite. IIRC, after I got done with my Emaxx SS tranny on V1, I think I got it down to 180g. I'll find my notes or reweigh it when I pull it out for a little service. The Revo I think will be more, but the brakes do make up some weight, 20g maybe? We'll see.

I have most of my parts now. Its just a mtter of putting everything together. The roller I got was a used nitro, and its dirty and smelly, so I'm taking my time going thru it, getting as much as the oil and grime off, going thru all the bearings, re-oiling, and basically doing a whole tear-down. My V1 was a truck that was bascially a new 2.5. Guy had the motor frag during break-in, got pissed and sold it. Got a barely used truck for 1/2 price :) What a difference in cleanliness. V1 has barely seen nitro, so no dirt sticks, the V2 roller is lightly/mod used w/ nitro and there is sticky oil all over every surface. What a pain. Yuk.

Since I have a Revo to play with, I'm taking my time on this one. I'm actually going to be Chester NY on memorial day, so was hoping to make it to the Barn, but I don't see that happening. :( I could bring my v1, but its very much setup as a basher, and since I've never raced, it would be pretty ugly. I don't even have good racing tires. Is there a RCM bash this year? I'd really like to make it to there. Hopefully either the Tekin MT or MMM will be out by then as well.

Work has been moving along. Got the basic chassis all back together. Got (one of two) trannies modded, and got the bottom plate for the batt/esc tray completed and mounted. Still have some work on the batt tray. Needs straps and some guardrails. Then just need to mount electronics and then I will be good to go. I'm waiting on 500K oil for CD, so I got an FOC for the stock 2.5 tranny and have that mounted. Weight was 220g IIRC, but got excited and didn't write it down. I'll get better weights later.

Did the 2nd gear locker BrianG style. I notched the clutch slightly to fit the 4mm screws, and tapped the 2nd gear as well. I lined up the clutch so that the drive arm is engaged, and the notches hold it solid as well. I'm sure I could have used just two screws, but no biggie. I made the notch in the clutch so that the arm could not disengage even it wanted to. Its def solid. I had socket head screws, but button heads would work as well. The screws must be 4x10mm tho. Any longer and it comes out the back and into the drive gear (not shown). I have man brakes, but this way I can simply switch back and forth between motor brake&reverse or man brakes and Fwd only. May just keep the 2nd tranny so I have one with a CD/rear brake, the other with a solid axle and possibility of reverse. Its easy to swap the two out.
