Power HDTR-4 Micro Waterproof Metal Gear 2.6kg / 0.10s Diff Lock/High Low Servo for traxxas TRX-4 savox swo250mg

Fits perfect, and seems to have more torque than the factory Traxxas servo. Also it works perfect when pair with Hot racings servo horn.

I would buy this one over spektrum micro servos. I use this one for my scx10III to changes the transmission form low to hi. This is worth the money. I will definitely buy more from seller

One of my TRX-4 shift servos died on me. Traxxas wants almost twice the price of these for their metal geared one. I bought two, one is a spare. So far I am not having any issues with it and works great. Fit in the mount better than the original servo. A month later had to replace the other traxxas shift servo. So far these are working great.

Somewhat fits in my scx24 + some washers, enough to work reliably and provide considerable improvement in steering power and minuteness of angle control. Thumbs up!

Installed this on my trx4 sport that I put a 2 speed trans in. So far it has held up great vs the stock Traxxas micro servos that burn out in no time

I used these for a traxxas summit.They work and hopefully will last but they don't fit properly in the mounting bracket.The factory ones have a lipped shoulder that fits into the bracket and these don't.So if getting these for a summit you will need at least one traxxas servo or modify the bracket.

Drop in replacement for the stock servo in trx4m.Stock servo horn is also a direct fit to this servo as well.

Purchased this servo for my 1/18 traxxas prerunner after the first run the stock servo blew out. This servo is much better metal gears can't go wrong with them. Fit perfectly no modification needed. Would recommend to anyone looking for an upgrade.
