Hpi MT brushless conversion

I got a hpi mt in a lot and thought that it would make a great electric truck since there is little choice for an electric 4x4 stadium truck.  It had no motor an no upper deck so I will walk you through the process that I took in making it a brushless MT.

The next thing is to work on the layout of all the electronic and figure out where to put everything.  The first thing I decided was to locate the motor on the other side as where the nitro engine was.  I did this because of space and the layout of the steering servo.  So you will need to rotate the center diff.  Not a big deal but you will need to drill out the holes to mount it.  I lined up two holes and then drilled the other two.  Here's a mock up of how things are going to look.

Next it is time to make the upper decks.  I first thought to make them out of metal but decided to use plastic for weight savings.  I found a left over part in my bins and cut it down to fit above the rear drive shaft.  I also used a battery holder left over from a rock crawler.  I also cut down the stock piece for the front mount.

Next I need to mount the servo.  I used some simple mounts from another kit.  I think its from a duratrax evader.  I also need to strengthen the chassis so I got some plastic from the local hardware store (a post block mount) to cut up to make a plate.  I screwed it to the existing upper deck and the center differential.  This really made the chassis more ridged.

The only thing left is to mount the motor.  I got a piece of angle aluminum and cut for a mount.  It worked ok I don't have a CNC machine so I cut it with a dermal so its kinda hack but works good.  Had to get a mod 1 pinion for the motor and then just install and paint body.

Time to test it.  Check out the review
