Here are my thoughts on the Matrix5
Short Course Truck - Looks realistic with the body style and scale wheels.
Engine - 30cc of unkown origin, not a Zenoah or CY. I did not do a teardown to check what the engine was comprised of as far as piston and crank sizes.
Air filter - can style filter used on several other large scales, such as the Firehammer
Tires - made for the scale look for the basher. Racers will want to upgrade to race proven tires by using FG adpaters and aftermarket wheels.
Wheels - scale looking with square drive. Glued tires, no beadlocks. Worn tires will probably need to repalce as a glued set.
Body - very good looking, made of PVC. No damage during filming and we were abusing it. Be sure to tape and shoo-glue it before use.
Radio - Radio is a 2 channel FM, made by Skyion. Has 10 channels as a plus. Should work with the Killer
RC kill switch made for 2 channel radios.
Servos - comes with throttle/brake and one 1/4 scale steering servo. The chassis has accomodations for a second steering servo.
Drive System - FS drive gears made of plastic. CVDs for the asles.
Chassis - Aluminum, flat with a slight bend on the sides for strength. I will be adding some more bend on mine to stiffen it more.
Shocks - aluminum threaded, oil filled. Not sure what they consider oil, but it was too thin for this track. Recommend a 40 or 50 weight to get better handling and less bounceability.
Screws - Mixture of Phillips head and allen machine screws and plastite screws. Not sure of the longevety of Plastite screws, make sure you check after a few runs.
Factory assembly - Made in China, needs a full pre-run checklist with a bottle of loctite and wrenches.

Long Term Testing - We will continue to long term test this truck at a backyard track in SoCal over the next few weeks. Set-up and testing will continue until we feel confortable to do another video showing it racing against other 4x4s and large scale trucks.
