Thanks please share it because not really any videos showing a simple way to upgrade the dig servo!

Can you do the same for the 2 speed servo?

[@Ferra3904]

I'm sure you can. I locked my tranny into 1st gear so wouldn't know if it's 100% possible.

[@brandonr2188]

whats the part number for the servo saver mount? i looked it up on google and couldnt find one specifically for the diff servo, only the steering servo.

[@Ferra3904]

Its a diff sevro saver for the micro servos that are in the traxxas trx4. www.amainhobbies.com/hot-racing-traxxas-trx4-aluminum-control-link-servo-arm-blue-hratrxf24p06/p710172

Jared Ferra thanks

Can you use the factory TR-4 control arm? Can it be any after market control arm? ....or does it have to be the Hot Racing one?

[@Ferra3904]

You can use any mechanism that will connect the servo to the shifting arm. You can use a rod end and a screw if needed as long as it lines up and you set your endpoints on the servos correctly. Yes the stock trx4 servo saver should work for this modification. I used the hot racing servo saver because I had it laying around.

[@ramo0901]

Thanks! There appears to be a shortage of Hot Racing control arms at the moment. This was a major reason why I went with the TRX-4 Bronco over the SCX10 Gladiator. The Bronco hasn’t come in yet, but if I can wrap my head around this fix, I’ll get the Gladiator. Curious as to how this arm is the remedy over the factory SCX10 arm.

@@ramo0901 the stock spektrum micro servo is weak and if the endpoints aren't set properly before use it will fail quickly! I tried to use it and under load when the dig is needed the spektrum isn't strong enough to engage/disengage the dig gear in the transmission. That's why I changed it to the HD power trx4 servo. It now shifts no problem no matter when I choose to engage it! With the longer wheelbase of the scx10 3 gladiator, I think its the better performing truck but the trx4 has the more detailed body. It's ultimately up to your taste because both are great vehicles!!!

[@ramo0901]

Thanks, Jared. Its all new to me, so I appreciate you taking the time to explain. Some research made the servo choice clear. I just don’t understand the choice of using the TR-4 control arm over the original SCX horn. If you could explain that aspect, it would be much appreciated. As far as the choice of vehicles, I’m brand new to RC over the level of “toy”, so I haven’t taken to any of the brand biases I read about. I have an 11 year old with a Hosim 9125 basher and crawling with a partner seems twice the fun, so a short wheelbase TRX-4 and a long wheelbase SCX10 in the same stable seems like good fun. I also own a full-size Jeep Gladiator, so there’s that.

@@ramo0901 the stock servo is a 23 tooth spline gear and that's an oddball sort of compared to the trx4 servo being a common 25 tooth spline gear like the steering servo. The 25 tooth spline is used on almost every rc for the steering servo and that makes the trx4 servo easy to find a servo arm. Plus the stock spektrum servo requires a little plastic adapter piece for their servo horn and it's not a very strong design. Overall the trx4 servo is stronger having a 25 tooth spline gear and easier to find replacement parts at a cheaper cost. If you go with the Axial sxc10 3 gladiator you won't be disappointed!!! The scx10 platform is legendary for a reason and the aftermarket parts support is endless!!!
