I would probably go for a pair of traxxas 2075, , waterproof and for a buggy or small truck they should have plenty of torque to turn the wheels infact I run either a 2075 or 2070 for all my rigs, there cheap too which makes a no brainer for me plus not really a fan of hitec servos poped a few before switching to savox and havent looked back

Haha should read before I post I meant I use the trx servos for throttle duties
The only thing I don't care for is that the traxxas servos are all plastic geared with a plastic output shaft. Would be nice to get some metal gears in there so they last a while longer.
