Oh, fiddle. Can't have sent then, for whatever reason. Luckily, I happened to save that one into my outbox, so here's what I said:
"Hey Stu!
So sorry for the slow reply mate, I've just been so busy lately.
And that's the first time I've been called a guru!
So, a brushless CRT! That'll be a brilliant project mate...the CRT is one of the best platforms for a BL conversion with it's relatively wide chassis (good for LiPo positioning). You're bang-on with using an MMM, as that's gonna be a nuke-proof controller once the V2 is out (revised BEC, so will be totally reliable)...and personally, I'd wait for the Castle 1515 1y motor to be released. Like it's true-blue Neu cousin, it'll be a great motor on 4S LiPo with gobloads of power, and not too much of a ridiculous top speed (around 35-40mph or so, depending on how you gear). The 1512 could also be used (Castle will be doing a 1512 version), though that's more ideal for buggies. A 1515 should run cooler in a bigger truggy, like the CRT.
As for LiPos...well, it depends how much you want to spend. How much do you know about LiPos? At the moment, the NeuEnergy cells are amongst the best out there and also go for a great price. The easiest route to go would to be use one big 4S pack one one side of the chassis, with the motor on the other (or you could do a twin-pack setup...I'll explain about that if you want me to) NeuEnergy can do you a 4900mah 25/50C pack for $210, or a 5000mah 30/60C pack for $245. Both would run great in your CRT, though the 5000 30/60C would offer a bit more punch and runtime due to its higher discharge rating and slightly larger capacity. You could go down to a 4000mah pack without limiting power, but something around 5000 or even 6000 will obviously give you better runtimes and power. Up to you on that front.
You could mount the battery just fabbing up your own simple tray, with a velcro strap. RC-Monster also do pre-made delrin trays, which you just drill and screw to the chassis.
Then you've got the motor mount. RC-Monster do a purpose-designed mount for the CRT which fits in place of one of the centre diff mounts, so it looks very factory and is strong, too:

That's about it, really...you'd be able to do away with the mechanical brakes, or keep them if you want and disable braking on the ESC. I hope that helps a bit Stu (just let me know if it doesn't make any sense lol). You'll have to post a topic on this for sure!
Cheers,
Chris"
Hopefully that's of some help.
