Sent it in to them amd there customer service is top notch and is fast. servo was sent and received back in my hands in ten days incluedind the weekend. But there spendy.

So I vote hitec!

10 days? if i have to wait that long ill just buy a new one and get it in 3 days! money not really a issue when it comes to this hobby, its expensive to begin with.

This was a spare back up I have and just wanted it working again so time was no factor. Hitec has had one o my servos since the 4th and still nothing on weather it's fixed or what. So I have to give service to KO right now. If i needed a servo fast I would just go to my lhs and pick up a 7955.

i have spares also, but all savox 1267's or 68's. not saying ko servos are bad by no means!!!! way better than savox im sure! (never used them) but 3 times more money and still hearing of issues they have like all others. i must say after reading all the forums here, i get more confused than when i started looking! so many differnt opinions really doesent help anyone. dont even know why people ask...LOL. they buy wha they want anyway:lol::nod:

Hitec HV(High voltage) 7 series all the way. There is not a better built servo out there. I see a few people mentioning Savox, but they just are nowhere near as good specwise(and they don't hit their rated specs either) or build quality. THey are also known as power hogs and draw alot of current.

My personal favorite is the 7954. Its the High Voltage version of the 7955. If you run an unregulated Lipo RX pack your looking at a rather quick steering servo with .12 transit time and a massive 400 plus ounces of torque. And best of all you can find em for around 80-85 bucks shipped(TowerHobbies with coupon code)! The other HV servos are excellent too, the 7940 is as good as it gets for throttle/brake, the 7945 is a bit faster(with a bit less torque)than the previously mentioned 7954, and if you need absolute torque, the 7950 is an absolute beast nearing around 500oz.

Best combo IMO though is a 7954 steering and 7940 using an unregulated rx Lipo pack.

If you can spend the $$$ then the KO servos are well worth the $$. I have had just about every servo out there and the KO's are the smoothest, most quiet and most trouble free servos ever, but for the $$ you cant beat savox. The Savox are 2 for 1 KO.

In one of the newest magazines there was news about hitec releasing HV brushless servos that boast huge #'s for torque and hitec says they consume 1/5 of the power that their current servos do. The lines in the side of the cases looked red to me.

Hitec and Never look back,


Any one who claims they failed a 59XX or 79XX back to back has something else wrong with their set-up Period. When certain Paid Professionals remove the label from Hitec servo to appease their sponsors, It says Volumes.

Oh BOY right from Mike himself.




"Looks like a typo on the 9380 as is should be .13 sec. The specs are essentially the same as the 7940/45/50 but sip power and do not slow down as they are heavily loaded. Playing with the sample I got last week, I would hang 10lbs of weight on the highest speed version and it drew only .23A... the similar 7940 was 2.5A. Even when stalling the servos (can handle this indefinitely BTW!) it was only 1A. The servos are also dead silent and the programmability goes way beyond what we have now. You can modify torque zones so that on a throttle for example, you can set the end's so they draw almost no current when reaching a hard stop. Of course there are basic and advanced programmable options and if you get too far out of whack you can just reset to default or a previous configuration from a saved file. Also, each servo can be named and the history of it's usage is logged. So if someone sends a servo in and says it's new, we'll know if it really is!

FYI: These are nothing like the current competitors brushless servos, the motor and circuit have been several years in the making. The performance of the servo does not change above 7.5v so it will stay the same through the discharge of the battery. It also has a regenerative circuit which actually charges the battery when decelerating much like the high end ESC's for R/C cars therefor you'll be able to use much smaller batteries and still have plenty of run time. This is a huge advancement in servo technology as never before have we had so much power with so little current draw; it's like your corvette now gets 50MPG!!!

looks like they are trying to catch up with savox...LOL.....post that chart when you have a minute........let me guess....you dont or cant find it:lol::lol::lol:

SAVOX? LOL Savox servos are cheaply built and way over spec'd. They have been tested here locally and their 2 top HV servos were just a little "short" on their advertised performance specs. ;) :lol:

Catch up to savox in what nature ? Savox's have been Widely known as Power Hogs while these new hitec will blow them out of the watar as far as stall tq and power consumption, Hitec is Out there at the trade show's Compaing 1 brand to the next. The Proof is in the pudding Period.

Chart ? what chart ?

I am assuming that post about blowing hitecs back to back is directed at me. If not then I am sorry. But the last time I popped a servo it was a Hitec driver that set it up for me and it went out. this is when I decided it was time to move on. Now maybe your saying the driver from Hitec did not know what he is doing?

In my opinion Savox is the best servo for ME so far. I won't look at anything else.
