set up for BL revo.

[BrianG]

First of all, welcome to the forums!

The 9XL will be a good choice with 5s lipo or 16 cells NiMH. If you want to go with less voltage (like 12-14 NiMH cells or 4s lipo), go with the 8XL.

The ESC is possibly going to be expensive. If you go with 4s lipo/12 cells NiMH, you can use the Mamba Max controller. This will be the cheapest option. Some people successfully run this controller with more voltage, but it is running out of spec. You could get the BK Warrior 9920, but this controller does not have a cut-off for lipos, so you'll need an external on if you decide to do lipos. The Quark 125B is another choice (but pricey), but has a lot of programming options and will work with 5s lipo or 16-18 cells no problem.

You can use the stock tranny and gears (which are already Mod1) but you will either have to use a mechanical brake using a braking servo (and you will also not have reverse), or modify the tranny to use the BL motor for braking/reverse. To do this, you need to lock the tranny into second gear. Don't worry, BL power is more than sufficient even in second gear.

BTW: Your name says you are a Canadian RCist, but your location is GA? Is that Georgia or somewhere in Canada? Just curious. :)
