TRX-4M Defender
This is my first journey into micro rigs as I was fascinated by the capability of the TRX-4M as I'm familiar with the Traxxas' house design. Coming from the TRX-4 Sport TRAXX project that I've been working on previous, I've decided to jump into a capable crawler out of the Defender despite is rear weight bias.
PSA: The Defender comes standard with the following spring rate setup:
Fronts: 0.072 Rate [TRA9757]
Rears: 0.155 Rate [TRA9760]
I feel as though that this isn't common knowledge and should be something people should be aware of when deciding on purchasing springs, esp for the rears. The Bronco comes with 0.095 Rate [TRA9758] on all four corners from the factory.
Anyways, I've done the following upgrades and this Defender is a crawling beast. I will get a scale to corner-balance the rig when I get the time, but stock weight distribution ratio was around 48:52 (F/R).
