Hitec is using titanium for marketing hype. I think you'd be surprised it we were able to find out how little titanum there is in the servo (probably one gear, partial ti in aluminum). Ti would suck as a gear material, the metal's surface hardness is low and it has high friction. It is somehow both soft and incredibly hard on cutting tools.

That said, Hitecs top servos are great stuff, they last and you rarely hear anything bad about them, in R/C, that's saying a lot.

Edit: Did the OP really start a thread to direct us to another thread? Really?

5645 or 645....either or...they have been around for many of year's with no problems.







Ti gears Do Not wear as you think they might....Ace's Do blow gear set's more often then not due to being weak brass......75 for a servo that WIll have the gears let go at some point in its life....OR 100$ for a Hitec That WILL outlast every piece of plastic/metal on you car currently...the choice is pretty easy if you ask me.







look all im saying is that hitec should make their cheaper servo a little better,
in the centering department for the guys on a budget thats all im saying

I've broken everything else I've tried..guys at our club run orion but at .07sec I only have to turn down the speed and they blow them regularly so they end up spending more than I did on my hitecs anyway....there are some good deals on ebay for hitec as well..



did the people u know that blowed the orion servo up not tune down thier,
speed on their servo or not tune down thier steering throw they might have
had way to much, just wondering.

I think actually they might have had a bad batch as they buzzed even when not under load and seemed to get hot too..then they just died..
I've never bought a new hitec either..just get them "near new" off ebay at half price or less..last 5955 I had 2nd hand lasted 2 years hard racing and finally the teeth on the tiny brass motor pinion wore out..these aren't replaceable except by hitec as they come pre-fitted to the motor so I sent in the servo for repair and as it was discontinued I was offered a brand new 7955 for half list price..can't argue with that..
re the titanium..only the last 3 gears are titanium..the first gear is a metal/karbonite gear which works like a fuse in an electrical circuit.I think they cost around 7 bucks for a packet of 3 gears..and the tiny gear on the motor itself is brass..I've never even had to look at the ti gears for wear or not..fit and forget usually.

yea thats weird it might of been a bad batch that can be any servo though,
it does have a heatsink inside i believe so thats weird that it would get hot
it sounds like the computer chip just shorted out or a wire inside got loose
and touched something it wasnt supposed too.

I thought that but after the 3rd one blew I thought it must surely be his set up so I went over it myself and there was no binding or strain that I could find..no idea....

I am assuming OP is me? (not sure what OP stands for?)
But I did throw a thread with a link in here, as th ethread had been sitting in the electric section for 12 hours with only 1 person replying, now I have more replies and a larger range of options.

I was not expecting answers in this thread (but am happy to see answers anywhere) and checked here as I thought I would need to bump the question up.

Ok, more info on me and what might suit.

My driving skills are far from great, with the Sanwa ERG-VX that was fitted (and now dead) I found the car to be very twitchy - a guy at the track was trying to help me and he slowed down the expedetion (or something along those lines) on the transmitter and I found the car easier to drive.

Would the JR z590m suit me (since a quick servo I will probably only slow down anyway)

Spend the 200$ and go Dual Hitec 7955's and Dont look back....They WILL NOT let you down and aren't as twitchy as some of the high speed servo's out there.

I tend to favor, The 1313 Ace servos for steering on my buggy, and the futaba bl servo for throttle. It has great resolution and speed where it won't get broken as easily in throttle duty as it's like 100 bucks. the ace servo is like 75 bucks and if the gears wear out they are cheap like 18 bucks to replace, and I sent in the one ace servo that just stopped and they sent me a new one no questions asked. Futaba on the other hand are a pain in the neck to deal with. Now Jr servos are great, but expensive, but those are my three favorite brands...


I love the 1015's performance...I ran them for 2 years, however I found they just dont hold up that well... And when I went to buy parts nothing fit as ACE has had so many updates that the parts are all mismatched and not relabeled...... Had to drop out of several races dude to ACE servo's failing, and because of the hassle I wont run them any more...great servo when they are working, but definitely not as durable or reliable as the Hitech's ...... Same story with JR servo's, great when working, but failure rate is far too high for me to trust them...the only steering servo I will consider is a 7955..... I run a Futaba BLS on throttle tho, and I absolutely love it, but I wouldn't trust a BLS for steering, been there and got burnt ..... IMHO the only safe bet these days is a 7955...
