The 2650 should fit with the stock motor mount.

Thanks picked up a used RX8 2650 combo today.. Fits snug, need to gear it up a little..

Bought the RX8 a 2650 and 1900 2 3s 4000 lipos a and a DXe for 325.. thought it was to good of a deal to pass up, everything was less than a month old..

When using the speed calculator what size of tire do you put in for a short course truck?

stock tires are 4 3/8"

isn't the mm pro designed for 1/10?
As far as i know the hyper 10sc is a 1/8 buggy with a sc body, isn't it?

It's not based on a 1/8 buggy. It's actually based off a 1/12 Hyper mini ste, just stretched the chassis a little and added SC bumpers and body

We are now shipping our completely rebuildable Ballistic 550 motors; and we have announced our Havoc Pro SC/Ballistic 4.5 Short Course systems.

Bad a$$! Why cant other companies offer the different stators in their motors? For people that run at different tracks or people who race and bash could benefit greatly (from a monetary POV) by being able to just own several different stators instead of several different motors.....is their a weakness to having these motors be rebuildable like this?

We design and manufacture our brushless motors here in Irvine; we don't have to wait for motors from China. :lol:

We always have all of the components, replacement parts and accessories, to enable us to offer complex programs----such as rebuildable motors. This also allows us to support a fast turn-around time for service and offer a comprehensive Trade In program with a Lifetime Legacy Option. You can even design your own Ballistic motor with our Build-A-Ballistic™ programs; we will be adding a B-A-B 550 option soon.

Our controllers are also specifically designed to encourage customers to make simple repairs themselves----plugs, switch harnesses, TransCap modules, power wires. All service items are always available in our store. We have introduced new Short Course Systems with Traxxas-compatible battery and motor wires (2WD) to offer Plug 'N Race ease to Slash customers---both 2WD and 4x4s.

Most companies do pretty poorly in after market customer support because it's not a high priority to them. Also, designing and maintaining these complex options is a LOT of work.....:yes:

I run a Medusa 36-50-3300 on 2s Lifepo4 geared 18/52 and am yet to see motor temp over 95f. Using a Venom 120A Esc on 15 degree timing. With a 4600mah pack I get 20-30 minutes run time.

How many amps does the Novak 4.5 hv 550 motor pull?

Dunno what the max amp draw is but off-road (geared 13:54 in a Slash 4X4) I get 13-14 minutes out of a Turnigy 4500 LiFe pack before I begin to notice it slowing down. If I'm draining it completely in that time that's a little under 21 amps average. With LiPo having a higher voltage, the average might go up.

I gave up on the 4.5 and went with a MMP and Tekno Neu 1512 2d on 4s.The 4.5 glitched and hesitated like crazy with my CC MMP.
