aight im fixin to buy this motor here as soon as it comes back in stock, should i go 7xl, or 8xl? remember it is for a basher and im gonna be running a mamba maxx and a 4s lipo. is there much of a difference in the two? is one more preferred? thank you

Having run the 7XL in both a buggy and a truck and having run the 8XL in both a buggy and a truck, I can say a couple of things.

First, the 7XL is a beast, or as much of a beast as you can get on 4S; but after having gotten over the initial thrill of the 7XL, I found the 8XL to be a bit more practical. A bit less heat, a bit better runtime, not much given up in terms of performance. I like the 8XL better over all. Besides, 5S isn't outside the realm of possibilities for the 8XL either, if you're thinking about the possible future.

If you get to a point where you are trying to decide between the trakpower packs and the orion packs, beware.

Although the orion packs are made up of kokam cells, they are not the same cells that kokam uses in their 4800mAh packs. The orion packs are actually 2S2P packs rated for a 15C constant discharge. The kokam packs are 2S1P (or whatever configuration you get) packs rated for 20C constant discharge. The trakpower pack, IIRC, are 2S1P packs with a 20C constant discharge rating. I'd go with the trakpower packs.

i finnally got the revo in the mail and man i got a deal. i traded a set of tlt axles $85 approxamate value for a near new revo. it was missing one rear axle and all the electronics. i am gonna sell the motor and nitro stuff on
e-gay then put the money back into it. i also recieved my mamba max and made an aluminum reciever/ esc mount over the rear shocks from the shock bolts to the pipe mount. its very sturdy, pretty, and doesn't make it impossible to adjust shocks. i'll get pictures up as soon as i can. next its time to tear into the stock tranny and convert it. thanks for all the help guys

sounds very famillier.
Have you figured out if you are going with the E maxx trans. or the stock revo trans.?
Keep up the good work.

wow how did you manage the clutch and what are the benifits of it. well last night i locked the stocker in second(using brian's three notchs and three screw metod) and locked out the reverse, and removed the brake components. today im gonna try to pick up some aluminum from the machine shop next door and star the motor mount and batter holder. i shaved the stock engine mount and that will be where i bolt it up. im also hoping to pick up the missing axle components and a 40t spur gear at the lhs.

If I were you, I'd just buy the motor mount that Mike added to the store yesterday:

that looks killer but thats one of those "one day" deals. i am prolly gonna fab my own for now cause thats a little pricey for a truck i don't even have running yet. but thanks

If you fab your own, make sure you at least re-inforce the motor mount area with the optional brace and/or incorporate the stock Nitro mount in the design. The plate WILL flex without some type of shoring up.

IMO, $60 is not bad at all for the mount in Mike's store, especially since it is a 3 piece design that also supports the rear of the motor. This fact alone will help keep spur in good condition since the mesh will be much more consistent.

I agree, 60.00? WOW, that is a deal. Plus you get the customer service, the quality, and the assurance everything is nice and PERFECT!

but where would you mount the batteries?

On the other side of the motor. See my Revo in the link in my sig...

will the stock transmision hols up to brushless keeping it a 2 speed?

I don't think the revo transmission is all that. I wouldn't put my money on it.

But it's way better than the first t-maxx gearbox..

The only problem I've had so far is that one of the pins broke that holds the output gear on the shaft. It's not as strong as they slipperential, but I like the fact that it is enclosed (including the CD if installed), provides some gearing reduction, and can have a two speed system.

I've never used it as a 2 speed so I can't help you there (wanted reverse and didn't want to use a servo for braking). Personally, I'd be a little concerned because second gear is engaged by a single clutch arm on a little pin embedded into the second gear.
