Who makes the fastest servo out there?
Who makes the fastest servo out there, and where can I buy it?
I was looking online and it appears that Multiplex Digi 4 Titan has a 60ms servo (@6V). My current servo is running at about 140ms (@6V).
My application is a robotic TC3 that is competing in a national robotics competition to quickly navigate a track AUTONOMOUSLY.
Fastest servo would help me out a lot.
Thanks in advance for your advice.

Airtronics makes a digital servo witha speed of .06 its around $105.

Yeah, Ko makes the fastest and toughest servos out. They are simply the best. You can also take a look at the PS-2113 (not digital, and no metal gears).

Hitec 5925.
Mine has 3 years on it's back in Nitro TC and it's still hauling butt.
89 bucks

sweet, thanks for the responses guys.
I have another question...
What is the difference between an Analog or digital servo?
Currently I am turnign the servo by sending it a square wave of width proportional to the desired turn angle. Do analog servos function the same way or will I need to change my way of turning?
Also, are the digital servos more robust when it comes to noise?

Digital servos got way more holding power, finer resolution, more power around the center and faster response.
Dont know about input signals, but they are compatible with analog servos. Noise resistance, I dont know.

yeah i reckon KO make the best servos, but the Sanwa ERG-WRX is awesome too

ko ps2123, 7.2V
or
airtronics/sanwa 94758, 6.0V
both are 0.06 sec/60*, and digital. the airtronics could likely run off of 7.2V and yield a transit time of 0.04-0.05 if you are creative.
both analog and digital servos do take the same input signal, but if speed is truly a priority, do not use an analog servo as the response, not transit, time will suffer. digital servos get to 80% of their destination much quicker. that link that cole posted is a very clear explanation of this.
have fun.

Does anybody know where to hook up the fet wire from the servo when the ESC doesn't have one, such as the new Novak brushless ESCs?
Thanks
Thanks

JR makes the 9000s that is .06 at 6volts.
I'd imagine that if you ran a wire from the servo to the pos lead on the battery, you could gain some speed. That's what I heard Hara say, but I haven't tried it myself.

Thanks Besercoe
That's what I suspected. Just confirmed that with a friend who has the same setup. Just couldn't find that info in the KO or Novak literature.

i had a sanwa vrx .07 or .06sec something like that... i had to take it off. it just way too twitchy.... went to a regular servo and handle much better. much smoother, especially thru the sweepers.
