What is the Torque rating on the default servos which come with the Hyper 7 PBS, I was out in a sand quarry this weekend and every now and then the servo couldnt turn the steering even though the battery pack was full (6v 1200mAh flat pack). I had to manually turn the steering to free the wheels before it would turn properly. If I got a 100oz/inch (or higher) servo would this problem be resolved? and if so what effect would it have on the power drain? ie how long would a 6v1200mAh pack last on a full charge?.

thx.

It certainly will be resolved!! I guess the stock servos of the PBS is about 50oz. and that's too low for steering an offroad buggy

how about 70oz?

I've been running a Hitec 645MG steering servo (133 oz/in of torque at 6.0V) and an Airtronics Z590 throttle/brake servo (85 oz/in of torque @ 6.0V) along with my Team Orion 1200 Ni-mh pack. I get a full day worth of bashing and then some off one charge. To effectively turn a 8 pound buggy at speed, a steering servo with 100 oz/in of torque should be considered mandatory. The rechargeable Ni-mh packs carry more than enough juice to keep you pointed in the right direction and should last thru most bashing sessions.
