I recently purchased an RC8 buggy kit and two Hi Tec servos.

My local hobby shop sold me a HS 625MG and a HS 645MG - one for steering and one the engine/braking.

The question is I can't recall which one I am supposed to use for steering and which for engine/braking.

Should I use the more powerful servo for steering or for the engine/braking?

Seriously showing my ignorance with this question, I am sure, but would appreciate some guidance.

Thanks in advance,

Travis

You will want to use the 625 for throttle/Brake and the 645 for steering.

The 625 and 645 are great servos but in my opinion they are at the lower end of what a 1/8 buggy needs. The 645 would be great for throttle/brake but a 200+oz/in torque servo would be better for steering.

Thanks!

I have a 2 inch streched Savage X With ofna super offset wheels
This truck is raced , bashed and smashed. Hs-645mg for throttle/brake( a little slow , but strong) and an Hs-985mg for steering. Been abusing this servo for the last 6 months . no problems yet

985Mg is under 200 OZ but is holding out.

I also have this servo for steering my AX-10 Scorpion (gets a little warm , but after 50 hours of crawling it hasn't missed a beat
