Futaba High Torque Servos

[sedawk]

I'm just starting out and ready to buy an RC10T4. A high torque servo
is recommended for steering, and since I'm leaning toward a Futaba
radio I was going to buy an S3305 or S3010 servo. On Tower's site it
states "per Futaba this servo is approved for use with NiCd batteries
ONLY!", and "Use only NiCd batteries with this servo in all
applications because of the high amount of current this servo
requires. Battery types other than NiCd will not deliver enough
current to properly operate these servos". I was planning on
purchasing NiMH packs, but now I'm unsure what to do. Is this a valid
warning? Should I just buy NiCd's? Is a high torque servo necessary?

I would advise against those servos for one reason: TOO SLOW!! Oh, and don't
worry about the niCd vs NiMH thing, that would be if you were running a separate
4-5 cell pack for your reciever and servo.

Personally, the S9450($120) , S9402($80) are what you'd want in racing from
futaba although the S3010 ($25) is probably adequate.

In my car I have a JR Z4750 96oz/in and .12 60 degree time at 6V, and retails
for around $85.

And yes, a high torque, high speed servo will be very noticeable when driving on
the track, your car will be much more likely to go where you turn the wheel no
matter what the conditions. And when you get hung up on a tube, you can just
turn the wheels and if you have enough torque it will just push the front of
your car away from the tube :-).

Budget how you want to, I would put a quality ESC and charger and batteries
higher on the list than an expensive servo. Once you get that stuff you can put
in a quality servo, the 3010 should do you fine for at least a while. When you
stop crashing and start feeling the need to tune your car to go faster and be
more stable then you might want to upgrade.

I use a HiTec HS645MG in my monster truck for the steering. It's a metal
geared high torque servo that will happily move my 1lb wheels (yes, that's
2lb of load on the servo for it to move back and forth!) as fast as I need
to for bashing.

I strongly recommend this servo, for me it's perfect. However I have no
idea whether it's appropriate for what you want.

No it isn't.
Just because the wheels/tires MAY weigh 1lb. each, doesn't mean that the servo
has a 2lb. load on it.
I'm not trying to *sharpshoot* you, but
Remember.....
The servo is only TURNING, the wheels, not LIFTING them.
However, at near 130oz of torque, that HiTec HS645MG is a real brute, and COULD
handle a 2lb+ load if it had to.
I also recommend it.
