high speed servos -
12-20-2005, 10:02 PM
With my Mayhem ST...the stock steering servo--I am not happy with.
What would be a good upgrade to speed and torque?? Right now I do have Futaba S9302(yeah I know it is discontinued) that I could use. Specs on that one are: Weight 2.30 Torque oz./in. 99.00 Speed 0.19/60 Currently in truck now is the JR Z590M Torque: 85 oz/in at 6V Speed: .15 sec/60° at 6V Weight: 1.6 oz okay I guess by looking at this that the Futaba one would nto be a better choice for steering but better for the throttle I would say. If your not breakin parts your not going fast enough-Biodragen NTC3 RTR assoc .15 NTC3 OS .18 Losi 8T, JR8611a ST servo, Futaba 9350 Th\Brk Servo, RB-C6BB Motor and Novarossi 528XR.

save urself the frustration and spend the extra money for the futaba 9350's they are the most reliable and strongest servos on the market we use them for year in our buggies and never have issues, they are like 120$

Or you could go with the AIR 94358 I've ran them for a year or so and haven't had any trouble with it at all. Just another option.

Dude, if you want serious steering with holding power and torque get the airtronics or the futaba that czech it out is recommending.... They are very VERY strong servos that will take a beating and the rigors that racing will throw at them

I really think the JR650z will help you aqccomplish what your looking for in a servo at only $50. It's .17secs at 142oz....seems faster than .17secs to me comparred to other brand servos with about the same specs.
Then you could put the JR 590 on th/br

Tex that servo you mention is slower than the one I have now.
The only other difference is the torque JRZ650M--$49.99 Torque: 142 oz in @ 6V Speed: .17 sec/60 degrees @ 6V JR Z590M Torque: 85 oz/in at 6V Speed: .15 sec/60° at 6V So what are the thought on this one JR Z4750--$84.95 Torque: 96 oz/in at 6V Speed: .12 sec/60° at 6V Airtronics and the Futaba one mentioned are the $100 range but much more torque. So my next few questions would be... The torque verses speed. Where to draw the line? How does the torque affect the speed while in use? The torque seems to be okay with the one I have now but it is just a tad to slow for me to make sharper turns when I need it to. what about going from a 5 cell Rx pack to a 6 cell pack?? I know the old futaba one when I used in in my electric it was very fast and it was snappy but now in the gas truck is is sluggish. The only deal I see here is that the power came from the 7.2 volts through the ESC and in the gas one is is a lil Rx 6v pack. So that is my thought on bumping up the volts---what is the down side to this based on what I have above?

I'ma second John and Tex on this one-JR650's are the way to go. These are, by far, the best servo's I've ever had. The specs mean nothing- These'll torque the wheels side to side on my revo or k2 (I have one on steering for both) like there was no tommrow. These are great, for the price, These should probably be around $75...They could get that easy. Try one, and you will like it.
