May 14, 2018Application(s): Trx4 t lock
Comments: Bought 2 to replace the T-Lock servos in my Trx4, on initial test they worked perfectly. After complete re assembly of the Trx4 the wouldn’t respond. Very disappointed!

October 27, 2017Application(s): Traxxas Summit, gear shift, front and rear diff lock servos.
Comments: Amazing replacement of the stock 2065 traxxas servo. Metal gears ensure no stripping like the stock ones. Torque is not really impressive. But it shifts and locks my diffs. One of the few servos that can fit the summit and offer MG. Really happy with them. Also dirt cheap.
