    I found it to be too tight on the shaft and also too tight on spring tension. I added graphite powder and lightly sanded the inner diameter. Then run it loose as possible. Rich Duperbash has been beating the snot out of his with no more busted steering. He took my advice on a fix and has tested it fully. Basically it has zero give out of the box. It couldn’t cam upward on any impact. It’s also not the best design but way less breakage was reported after tweaking the action in the assembly.

    I’ll definitely do this as soon as a replacement comes in. They are on backorder everywhere. I called proline and they are going to send me a replacement set.
    After watching Rich’s videos, I’m like how in the world did I break my steering driving around in snow in my back yard and Rich launches his 60ft with no breaks. I’m definitely taking your advice Vanning.

    A bunch of people broke that part within 30 seconds of driving. You can take some sand paper, roll it around some round bar and carefully remove a slight amount of material. Make sure it slides easier up and down. Then apply a good grade graphite powder. Then set the spring tension so the cams actuate a little while steering. Then tighten up a bit more so it doesn’t operate with normal steeeing. Then watch carefully from the side as you set your end points. Study it for a bit.

    The servo saver has got to be the last part you want to break on this truck. It’s on backorder everywhere and proline shipping is incredibly slow.

    I think everyone on the planet ordered spares. I may test my skills at making an aluminum one. If I do bust mine ever. I’ve also had conversations with people that the servo saver isn’t really needed. Ive read it also on forums. i didn’t read too much into it.

    It’s also a poor design, it will climb the cam one way much easier than the other. In one direction, it has a hard time. All we can do is improve it a bit. I’m not hearing many reports of breakage after the first round. I’m still waiting till better weather.

    B2A96906-C6B5-44C1-B653-F459DEA091F8.jpeg I added some axle extensions also. I really like this mod. I used the more narrow set of RC8T extensions from Team Associated. Quality, sharp drill bits were key to doing a successful mod. Also, the closed axle Nuts will not work, have to use open ones. These made the stance one inch wider. From my few test rides, I knew it would be more where I like the width. The body is thick so it’s more top heavy than most. The added width is nice.

    T-Bone Racing has a skid plate and bumpers for the MT-4x4. I ordered a skid plate.

    I retrofitted their kraton chassis plate for the ProMT before they came out with the new skid plate.

    Diff topic: spoke with proline about the servo saver and got this reply “We have a shipment of re-engineered servo savers on the way from china . They should be to us by the middle of this next week your shipment will soon follow that.” This would explain the backorder status everywhere. I’m assuming other issues that have been brought to their attention might be in the process of being addressed(I have no communication to validate this assumption). However, it’s nice to know our voices are being heard about the problems we are experiencing and solutions are being delivered.
