can an emaxx center trans be put on a hyper 7 to convert it to electric? i know you will have to redrill holes and stuff but would this work? i was thinkn of dropping an emaxx tranny in the hyper 7 then throwing a vxl on lipos in.. who thinks it will be worth it?

I don't know, but why not use the proven center diff and do a regular conversion? The Monster Truck tranny gearing may not give you the speed you might want.

I'm also curious how the VXL ESC would do, but it also limits you to 11.2 volts (3 cell LIPO). The VXL might very well push a good strong motor quite well on the 11 volts, but the Velineon motor isnt enough to move the rig with any power / speed.

Here is our effort:

could you show me where to get motor mounts and stuff please for the hyper 7?
thankyou

I'm partial to Dan at www.RCProductDesigns.com

He, and others who are working with him have put a ton of work into the "total systems" needed to develope this new class within the sport. There are tons of details to be worked out, beyond the motor and battery mounts, ESC being just the start, a BEC and extra cooling, as well as the extra powerful motors themselves.

Whilst we used a Feigao 540XL motor for our Phase I test platform (Jammin X1CR), the NEU motors are thought to be the best value for the money. We intend to upgrade as soon as we can, more info here:

In addition to the Forum postings on Dans site, the following is quite a good FOrum to spend some time studying:
