will this work in a e revo?

[What's_nitro?]

Well I can tell you that's gonna be one powerful setup!

I really like 5.5mm bullet connectors for high power stuff. If you're gonna use Deans connectors, I'd use a complete set on each individual wire. I would also recommend using 10 AWG wire or larger.

I'm also doing a Revo BL mod and need some help! Not sure what type of gear to buy I'm going to use a 12L Feigao motor with a BK 9920 esc. What type of gear do I use on the motor 5mm bore 32 pitch pinion gears? or 5mm bore, mod1 pinion? What is the difference and why do they have so many?
What size ( # of tooth) would be best suitable for a Revo? I was planning to use the stock tranny that comes with the Revo or a Emaxx tranny if I can get a hold of one.

well i cant help you much but i used this http://scriptasylum.com/rc_speed/_top_speed.html to see what gears im gona us. good luck

Revo uses a mod 1 spur gear, so you will need a mod 1 pinion. Pinion size will depend on what batterys you will use. A 12l feigao has a kv of 2048, so 4s lipo or 14 cells would be a decent setup. Using the stock tranny and std tranny gearing, I would suggest and 18 tooth pinion. Then you could vary the spur gear as traxxas makes a 36, 38, and 40 tooth spur. The 18/36 gearing with stock tires will give you about 40 mph. Here is a copy of the speed calc with the numbers I used to find this. I used 4s lipo as the battery, but it is very close to 14 nimh cells voltage-wise.

Thanks for all the help on this lincpimp. Where do we use the 32 pitch pinions? on Emaxx Trannys?

Generally speaking yes. Since the Emaxx uses 32 pitch gears its easier to use 5mm bore 32p pinions on the motor (such as a Feigao or neu etc). If you prefer though you can get whole new spur/slipper assemblies that use mod1 spur gears, so then you would use the mod1 pinions. Mod1 gears have larger teeth so dont strip as easily as the 32p gears, but its a case of budget/ personal preference and how good you are at setting the mesh really.

Thanks for the info on clearing up the mod 1 with 32p pinions who would carry the upgrade kits for emaxx conversion from 32p to mod 1? Do they sell a mod 1 pinion gear that replace the stock 32p pinions on the emaxx.

I know this is a little late but I spoke with Mike on the phone about this exact question. I have the Emaxx tranny with a 1950 1800kv. I bought a RR Slipper kit for a RC10 MGT. Then I bought the Ofna spur gear from RC Monster store with a 18 or 20 tooth mod1 pinion. The slipper kit slides right on to the tranny. I modified the Ofna spur gear to hold the rotor plate. Little filing. Everything fit great. If you buy smaller pinions the metal spur gear sent with the kit would work. But thats a whole new thread. Lots of opinons about using a metal spur gear vs a plastic spur gear.
