Building a Mini-Z HM buggy!

If you decide to add a hatchback to your line up of Mini-Z RC cars here is how to do it.
Whether you use a new, used or old school narrow chassis the choice is yours. I chose to use a MR03 chassis. No VE motor or Li-po battery needed on this build. It's too much power for high motor mount (HM) cars, there would be a roll over problem. That would be less enjoyment racing with friends.


It's a good thing to start off with a gyro for better stability on compact cars. If you started with a wide chassis you'll have to do the necessary conversion set up for the narrow chassis first. The included manual will show you how to do this.

20 radial narrow tires for rear.
I'm building a VW buggy which is a narrow hatchback so I need a set of narrow 30 tires for front tires and a set of narrow 20 radial for the rear.

The Eagle Racing aluminum motor mount is a good upgrade from the original plastic motor mount that suffers from fractures and cracks.

Optional Eagle racing aluminum upper arms.

This aluminum friction mount is a must because the original plastic parts will not fit without it.

0 degree knuckle arms

Start by installing the knuckle arms and upper arms to get that out the way, but don't forget to put in the purple soft springs along with it.

If needed use a fresh stock motor for optimal performance since they are replaceable.

The motor mount is equipped with a nice low profile heat sink, but the motor has high protruding soldering and glue that may cause rubbing on the car body. If so you can rotate the motor oppositely to prevent this, but sometimes the capacitor may cause a problem. 

Ready for the friction damper.

All there is left is to get the AAA batteries in and put on an autoscale body.
