While the JR's and KO's leave you with a DNF the Hitech's will still be kicking and winning the race.... I honestly could care less about the torque ratings as they are only for bragging rights IMO after 200 oz/in...the real concern is durability , and the 7955's are by far the most proven, reliable, durable servo's on the dirt....You wouldn't get me to run a JR 9000even if it was free, I do not trust the 9000 series one bit , seen way too many of them fail this season....... Interesting article tho, but IMO it misses what a smart racer looks for in selecting a servo....having 6 million oz/in of torque means nothing if the servo is broken down, and truly in buggy or truggy we do not need any more then 200 oz/in...IMO the ACE 1015 is the strongest performing servo there is, however its unreliable which makes it useless to me....

ive only had ONE jr servo fail on me which was my fault, i started racing in sept 08 along with my dad. He bought hi tec at first. Every hi tec servo he has bought has been sent back to get replaced and he bought jr to put in there place. We have about 4 brance hi tec servos sitting in our pit box for back up. have not needed them

You missed my point, I never said that Hitecs were a bad servo but they are not as powerful as the box states. Maximo any servo can fail even your mighty, proven, reliable and durable Hitec.

I use 7955's and I may be wrong but I feel the torque is overkill.If a buggy weighed 40lbs I could see needing that much torque, couldn't they trade off some of the torque for speed if they changed the gears to a different ratio????

:lol:
:lol:

Looks like a sweet servo tho!

my hitec had a problem of not centering. They said they would fix it for nothing. And i don't have the reciept. One day i might. Not really a big deal for now.

Ran into a car tire at wot. Folded my chassis like a lawn chair. Drive shafts like shock springs. ripped my lower arms of the hinge pins and broke the tie rods in half. Servo is perfect with zero play.

reliability factor :nod:

Fast throttle servo's are OVER RATED.....you DONT need anything Uber fast....all fast servo's do is force the driver to either adjust expo or really learn how to calm down the finger's and not over correct or over throttle a section of the track...I cant say ive personally EVER seen a 5955 or 7955 fail as of yet.....Hitec in all the year's is Known NOT to charge for repairs and warranty....i Dont know what you did to get charged losi_racer...but that is Out of the norm for hitec....they are normally phoning to ask what New version of the servo you want.



Frank L Do me a favor and open up one of your old 9100's or 9000's and check out the top case....compare it to your Hitec and same with the gear set's....visually see what im trying to tell people in regards to durability and longevity of the parts....the JR's are missing that crucial link if you ask me.



as for required Tq amount...200oz is minimum imo for both buggy and truggy.....no sense having not enough when its just as easy to have too much.

My buddy has not 1 but 6 of the jr hv! Every one of them he put in didn't last a full day of racing. Not bashing just sharing the experience. Jr tells him it's something in his linkage setup. The guy has been racing 10 years and is well knowledged in rc. He put it a hitec 7955 a couple of weeks ago and has had zero issues. The new hitec hv seems to be overkill but at 50 bux less then the jr and i'm sure alot better quality sounds like a no brainer.

im runnin a 9100t in my buggy,thats more than plenty for me:nod:

Also my experience with JR servos were bad, just decided to try hitec but not7950 series, i ll try hs7940th series, both for steering and throttle. A lot of my friens are using hitec servos with zeero problems.

crawldad91,


see the problem in lies 6 months down the road from now when the gear's and sloppy and the top case let's go and or the motor's fail......Im not trying to Bash your oppinion...but from what most of us have seen (the Hitec guys) the JR's fail alot more often then Not....again ill state the BRASS VS Titanium debate....its a no brain er if you ask me.


i know i must be coming off like a jerk right now but im giving you my honest opinion...there's no more to it....i hate seeing guys with servo problem's...they are Expensive enough and buying twice Sucks....ive seen it all too many times.

To me its not even an issue. We already spend but loads of money in this hobby, so to be absolutely issue free with the servo's it's gotta be 7955's or the new 7950's. Spend the cash and be done with it for a few seasons or more!

The 7955 is hardly slow for steering. Most high speed servos get slower when they have to work hard. The 7955 deosn't seem to slow down much. I even use a 7955 on throttle now, I'm at 8.4 volts though.

Wanna test it? Just hold your front tires in place and try to steer and let the servo and servo saver in your car fight. I've yet to see a high end servo blow though the servo savers travel as quickly as the 7955.

And at 8.4 volts unregulated Lipo it moves as fast as anything I'll ever need. (.13)

can't wait for the 7950 HV and 7940 HV. I wonder if the 7940 will be powerful enough for steering?? I think I'd use it for steering in a 1/8th onroad, but probally just throttle in offroad.

I've only tried a couple Hitec servos but I've never had one that centered well. Maybe the newest ones are better but I wasnt impressed. I still consider them a budget servo. I have an old Airtronics 151 that still works awesome (15ish years old!).

I'm a firm believer that you cant have too much torque. I despise servos that dont center well. Speed needs to be quicker than .10 for me.
