Hitec's. And if you're burning them up, you're doing something wrong.

I remember reading when they were first released that the, 7940's had some problems, but if memory recalls it was gear failure. The 7950's were good to go, and A ton of guys run the 7955's unreg lipo with no troubles, and those servos are BULLET Proof... Assuming you set the EPA correctly..

If you are considering a JR, then think again, those are the most failure prone HV Servo out.. I know 1 guy that has gone through 4 of 400oz $200 JR HV's, he switched to Futaba on a Reg.. And basically all the other guys I've talked to about the JR HV servos have had troubles..

Only trouble I've had with a HiTec was a 5985 that was fixed under warranty, motor and main gear went bad, I used it for steering for a season, then moved it to Throttle for a season, went out at the last race of the season, as the race ended..

one of the hitec servo works but it is like it has a broken connection in side as it will stop and you tap it then it works then stop at half travel etc. i am sending them in at the moment for a warranty repair but wanted to ask the q about what is best. the other just stopped dead and it was on my throtle it was half way thru a race went this happened.

Hitec HV servos are the best on the market. If your burning these up you are not setting up your EPA and linkage up correctly. I am very hard on servos and burnt up alot of servos. These Hitec servos rock.

When the jr hv servos first came out I put them in my buggy and truggy and within 3 races I had one fail so I ripped them all out and went with the 7950/7940 from hitec. They have worked perfectly. I do have to say the jr servos are very pretty to look at but they either work or don't right out of te box. Look at the pro guys most of them run hitec servos there's. Reason for that.

I have been very happy with my JR HV servos. I burned up a lot of 9100T's (9 last season) and JR finally replaced them with the HV servos for me. I have had no failures and have been running them for almost a year now in my losi 2.0. I also have a 7955 that I run in my losi 2.0E and it a great servo and at a good $.

No i did not have 9 servos. I had 5 servos(2 in buggy, 2 truggy and spare) and between them all they failed 9 times. They replaced 2 with HV and i sold the other 3.
