set up for BL revo.

yeh, im from canada originally, (thats my email, so i just decided to keep it the same. but i live in GA now . so yeah lol ) .

well the revo im getting has FOC (foward only) already installed, so will that do anything? i wasnt planning on running a lipo yet, there a little pricey, so nimh is good enough for me for now.


would Warrior 7020 Brushless Car Controller work as the esc? it says it can handle 20 cells, but i dont know what the motor is supposed to match up to O.o .

or would a Quark 65 amp Roadster Car controller work ? lol this is confusing me.

how big of a shaft on the motor should i get. and how many tooth on the mod 1 pinion ?

and does it help or not to run the rechargeable batt pack for the receiver ?

First of all, what do you want this truck to do? Are you looking for high speeds comparable to the Nitro Revo (45mph+) or is this strictly for track use?

If you want super top speed with fewer cells and/or lower current ESC, I'd keep the two speed. A motor with high-enough torque to launch the Revo to high speeds in one gear will draw too much current IMO. This means you won't need to do anything with the tranny other than the FOC, but again, you won't have reverse due to the internal OWB. And you'll need the stock brake.

However, if you are looking for 30-35mph top speed for track use, then locking the tranny into second gear can be done. This will let you remove a couple other internal parts as well as the brake, brake servo, etc.

You can find a motor that will work with 18-20 cells, like the Wanderer 10XL, but I still think the current will be too high for a ~70A controller. The Revo is a heavier truck and needs some torque to get it going effectively, so I'd stick with the XL size motor.

An 8XL Wanderer motor, Mamba Max ESC, and 12-14 NiMH cells should do it for you relatively cheaply. The Mamba controller is rated for 100A and 14 cells (some say it can run 16 cells but I personally wouldn't). The 7020 can only handle 70A, and the quark only 65A. For a larger truck like the Revo, I'd stick to at least 100A like the BK 9920, Mamba Max ESC, or the Quark 125B. If it were me, I'd go with the Quark and the extra heatsink found in the store.

You'll also need a UBEC or receiver pack since 14 cells is too much for the Mamba Max ESC's built-in BEC to handle. You can use a receiver battery pack, but that's adding more weight and one more thing to charge. Better to use a UBEC.
