Can the Spektrum H6040 Heli Servo be used in a 1:10 touring car or 1:10 buggy? Spectrum calls it a Heli servo and not a surface servo, but I don't think it makes a difference.
The speed and torque numbers are incredible.

I called Spektrum.
He said Air servos have a tiny deadband.
Surface servos have a large deadband.

Using the Heli servo on the ground may burn it up because the ground is constantly trying to push the servo. That does not happen in the air.
He recommended the JR 9100s for about $130

I put one of these in my XXX-TCR. We will see how it holds up. Works great so far! That JR servo is $60 more!

We will see how it goes. Worth the chance for me for now. I knew some pros in the past that ran air servos in there cars as they centered better. May be the zero dead band!

Yes, this servo can be used in any surface car. I've been running a test unit for the past couple months and love it. It's very similar to a JR8800s, but more torque and more compact as well. The servo weighs considerably less than a JR9100s as well.

Spektrum is going to make "surface" specific servos early next year, but it's really just a small case change moving the ears and a shorter lead wire. Otherwise, no different to the heli servos.

Great servo and has held up great to some HARD wall shots in my touring car. Touring cars also put more strain on steering servos than off road cars from the much higher speed cornering forces and it has NO problem doing that.

I have one showing up at the shop this weekend to use in my offroad truck. By reading the specs it should easly hold up to cars and trucks. A heli and especially if hooked up to a gyro is way harder on it than any 1/10 car or truck can ever do to it and especially depending on how you have your heading hold set.

Yeah it will be awesome to see a surface servo come out with the ears further forward. This servo barely fits in the car. It is an impressive servo though. I love it so far!

I've been researching in www.servodatabase.com lately. They have 1,726 servos in there. It's great, but it could use some more data and reviews. I'll try and do my part and offer some.
In general, I think I'll have to buy servos and just try them. It'll get expensive.

Very interesting site. I agree you really don't know what you are going to get until you see one in action. I know Airtronics has fudged there numbers for years. There is no way my 94758's are as fast as they spec. My Orion and Spektrum are way faster with .07-.08 speed vs the airtronics .06 claim. I had a .10 futaba that seemed faster as well. Not sure how they get there specs.
