1/8 Buggy Servo?
#1
I'm looking for a descent 1/8 Buggy steering servo, and Hitec seems to have a couple right in the mid price range I'm looking at: around $80-$90 USD.
5925MG - 128 oz/in, .08 s
5945MG - 181 oz/in, .13 s
Which of these (or others) would you recommend and why?
Also, what's better about the higher end 5997MG servo, compared to the 5945? They seem to have the same specs: torque, speed, metal gears, coreless motor, etc.
Thanks.
Pete.

I am using the 5945 for steering on my 1/8 buggy and I couldn't imagine a better choice. It is lightning fast and very strong. I went from a 5625 (131oz/.15sec.- it's in my elec. truck now) and it was a night and day difference. For throttle you should get something like a 925. Digitals are suspect in the throttle.
I have heard that the newer ti-geared servos from Hitec are excellent. They have new amplifier designs that aren't supposed to blow if stalled for longer periods (like lots of braking). They are supposed to be great for both positions.

Thanks for the info on the steering servo.
For throttle, I thought I had a good idea of what I was going to use, but I didn't realize that digitals were suspect in throttle use.
I'm now concerned about the digital amp blowing under sustained braking.
Do you know why analog amps doesn't have the same problem? Or do they?
Also, anyone know if this a general issue with digital amps or specific to certain models/manufacturers?
I thought the whole point behind Digitals was better holding power with full torque at lower angular deflection, for a less spongy feel. On a throttle/brake application, that should keep the throttle more precise and braking more consistent.
Originally, I was thinking specifically of getting the 6635HB for throttle/brake. The Karbonite gears would generate less RF noise (the throttle servo is right next to the radio box), and gear strength is not an issue with throttle since it doesn't take impact like the steering servo.
But it sounds like I should reconsider.

The problem with earlier digitals was that the amp draw did not drop when the servo was under stationary load and the added "holding power" is what caused the amps to fry. The newest Ti geared servos have not had this problem that I am aware of (I have not tried them myself) and Futaba users use a digital for throttle/brakes with no problems. A Hitec rep could probably clarify this for us.
