im planning on putting a 1/4 servo in my emaxx. i also plan to buy a MX-3 at the same time. it says here (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLN93&P=0) that there is Y harness to conect the servo to the reciver and battery bacause the servo draws too many amps (700 mA w/ no load) for the reciver to handle. is this true? can anyone tell me about their experiances with this combo? thanx in advance!

The steering servo that comes with the Emaxx puts out 80 in/oz of torque, and it does the job adequately. Why not just look for another standard size servo that puts out more then that, like the Hitec 645mg servo. It puts out more power then the current one, plus you don't have to worry about making a 1/4 servo fit or a wiring harness.

133 oz torque... doesnt seem that much... can it move the wheels lock to lock VERY fast while just sitting still? if can, i'll get it... even better. try take a movie of it. if u can, could u email it to me? ill post my email if you can.

I have the Cirrus CS-80 MG in my E-Maxx, which has 129 ounces of torque, and can turn the wheels lock to lock on concrete. Not that fast, because its transit time is only .25, but that is a lot of torque. A regular servo with 110+ ounces of torque will do the job great.

only concrete? aw... kinda want it for scale looks too... backing up a trailer with a truck that wont steer until its blasting off at about 10 mph... not too good if backing up a boat through soft sand... :(

Your definitly gonna need a a seperate pack for the servo, because 1/4 scale servos need alot of power. Other than modiflying the car to fit the servo all you do is: buy a y harness and a seperate reciver pack, attach the pack to one of the female plugs and the servo to the other and put the male plug in the slot for the servo. You have to find a place to put the second pack, but that shouldnt be hard.

Id get somthing a little faster than the one you listed like .14sec transit at most, I dont think a .19 transit time will be as fast as you want it to be, You can sacrifice some torque, the servo you suggested has way too musch torque anyway.

pro3/nmt105- thanks for your advise about the pack. also, the servo im looking at has the speed of .19 with 4.8 volts. with 6 volts, it goes .14. :D
