Hitec 5955. A little pricey to start with, but you won't be replacing gears with these ones!

When I buy one it will look like this.

I like the cheap servos, I don't cry when they die. Plus I've had reasonably good luck with how hard on them I am. Towerpro995

A couple of words of wisdom on the 5995. First, it has 180 degrees of rotation as compared to 90 degrees for the 5955 and most other servos. Unless your radio has EPA, don't buy the 5995, you'll toast it within the first run.

Second, the 5995 has been known to overheat (mostly when run for a long time in high temps). You can inject heat paste into the servo case and it seems to solve the problem (just make sure you use non-conductive, non-capacitive paste), however it voids the warranty if anything else should ever go wrong.

The 645 is a good servo for 2.2s. It's just a little underpowered. With the higher end servo, you'll snap servo horns before you break anything in the servo. Watch your fingers around these. If they have enough torque to snap aluminum servo horns, they'll do the same to your fingers!

Hey ecoli i think your correct and thats what happened to my first two they were 180 and they would get quit hot and its the motor that failed in both.Makes sense thats why my tires hit the link arms.New to the hobby but should have noticed makes a guy feel stupid.
Thanks for the info now i know why they failed so quik.

well i just toasted a 5955 today, wasnt the gears, unlike the pos 645s, this time i let the smoke out. in a 2.2, with it runnin off of 6 cells direct:Brunette: cant complain though, it was on the super for almost 2 years, maybe it was tired?? it was bound up pretty good, still turning, just slower, then it overheated. hopefully the newer versions on my clod hold up better. im at 3 645's with 2 extra gearsets, and one 5955 board, maybe its time to switch brands :bugeyes:

Send it back to hitec, i bet they will prorate it and give you the new 5990tg for like $50. I have heard of a few people who have done it.

Hey, I get that way, too.

If you were a bit experimental, and had a 645 with bad gears and a 5955 with a toasted board or motor, try to combine the two for a super strong 645 ?:drooler:

thats exactly why i tore it up :) but the 5955 motor is soldered direct to the board, and if i use the gears from it on the 645, i need the drive gear from the 5955, which i cant get off the motor :rake: anyone need a gearset, lve got one, lol

ok are you guys talking about the 5995 or the 5955? Because ecoli said 5995 first off but now you guys are saying 5955. I was thinkin about gettin 2 of these 1 for my crawler and 1 for my Savage as they seem pretty good 333oz for 94 bux from greathobbies...either that or a 985 or 5985 (digital version) for 174oz. I have a 645 in my crawler right now and it seems fine but it does bind up easily...and it's not strong enough for my Savage. Not sure if I wanna go and spend 200 bucks on servos though...the 985 is only 50 bucks so its half...

I know the Hitech's are a favorite among the crawler crowd but look into the Futaba line up. The BL351 has more than enough torque for a 2.2 crawler, and around the same price as the 5955's as well. Even the Ace/AE 1015 would be great.

In my opinion, and remember it's opinion, Hitech's customer service is crap.

I'm all about towerpro. I'm a noob but did lots of reading to find out what servos to get. If you have a towerpro you bought from ebay it's most likely a knockoff. Thats why they have now changed the name to towerdpro so you know the difference from the knockoffs and someone that orders direct from towerpro.

I have cracked two cases and never blown any gears. And the new 946R looks like new plastic that might be stronger. So I've spent $40 in servos that are still going strong and you can buy replacement cases for about $5 too. Still got plenty more to go through before I come to the price of a Hitec.

I order from this guy but he's sold out now http://www.jpcustomrcs.atomicshops.com/catalog/item/4457875/5381533.htm

well i run 5955 in my crawler and my savage x its the only servo that will turn the wheels under full throtle..kool.. in my trail rig i use the 5645 it has the same quality as the 5955 and more torque than the 645 and its way cheaper than the 5955.
the 5645 has 173oz at 6v and 143 at 4.8 .the rooster esc has a 5v bec so the regular 645 has only 100oz at 4.8 so thats why its under powered..
now Al <heyok> told me that if i ran an external bec from castle creations i could get up to 8v or more for the servo..very kool
