About this part
The Spektrum S6240 servo offers a high-speed solution in a compact form factor for 1/10 class vehicles. For select 2wd and 4wd buggy platforms, a shorty style servo is preferred to allow for extra real-estate to mount electronics in the chassis. Additionally rock crawlers, monster trucks, and touring cars can benefit from this servos smaller than average size.

This servo is the replacement for the ever popular 6040 spektrum servo. Awesome servo, centers fine every time, doesnt have the hippy hippy shakes like the protek line of servos seem to be notorious for. I run this s6240 in my practice TLR22t 2.0 and I run the s6270 High Voltage in my race truck, both servos are awesome , haven't had any issues whatso ever out of either one. The speed of this one at .08 should be plenty fast for any application, the 6270 servo is like .05 and thats just overkill imo. I also like that this one has a little more torque for holding power better. Ive run the Reedy High Voltage High Speed servo, Protek 160ss, Protek 100ss, Savox 1258tg and 1257tg and this s6240 is my favorite of them all, highly recommend this one. If Frank Root of TLR racing and Ryan Dunford (owner of Spektrum) both run this s6240 in their personal Mod Trucks then you cant really go wrong.
Got this servo to go into Losi 22T4 truck, for racing. I looked for a servo with high torque, high speed, good price point and a rated manufacturer. This one ticked all the boxes on paper so hoped it would make the trip when it was installed. And it did, in spades, it is rock solid, profoundly quick and accurate and it is great bangs per buck. Just taken a second one, for another truck application. Highly recommended.
Super powerful, super speed, centers perfectly. It took lots of bad hits with no issues what so ever. I think its the best low profile servo.
Im sure I'd love the servo if I could use it but the round plug is in the way in every car I've tried to use it. Not a valid replacement for the s6040.
Was a great servo overall, use it in my mod buggies and stadium truck. After a year of hard crashes (full speed, tumbles, poles, etc.) on turf and dirt in my 2wd mod buggy (the oldest servo) the main steel gear shaft (internal) had broke, so the servo was not recentering properly and would slip. Teeth are all plastic except the main gear that's on the same axle as the external servo arm mounting gear appears to be steel inside. The replacement gears are a little over $30 from Amain last I checked, but the shaft that broke is not replaceable from what I could find. Sucks that I have to chuck the servo now. Will keep using the servo but lost a little trust in the other two I have running in my other cars now. Update: only 4 months on my second servo before it failed in the same area. Will not buy Spektrum servo's anymore, look elsewhere.
Reviewers generally praise the S6240 for speed, strong torque, accurate centering and value, with several owners running it in multiple vehicles including touring and racing trucks. Some describe it as durable through heavy impacts. Two reviewers report problems: one found the round plug obstructs fitment in several cars and so it is not a drop-in replacement for the S6040; another reported an internal main gear shaft breaking after a year of hard crashes, with the shaft not separately replaceable. A separate low-rated review describes the servo losing centre after a timeout. Reviews are few, and the reported failures are individual cases rather than a clear pattern.
- + Fast response speed
- + Good torque for holding power
- + Accurate centering for most owners
- + Good value for the performance
- − Round plug can obstruct fitment in some cars
- − Internal main gear shaft reported to break after hard crashes
- − Centre drift reported after a timeout in one case
