2nd That !! Just bought my second one. Low profile, look great and excellent performance. At $63 bucks you can't beat it and right now they have a trade in special promo going on. Buy the servo at 20 bucks off (Yep, a brand new servo for 43 bucks !!). When the new one comes in, send them an old crappy servo in the supplied mailer. Thats it. So simple even I can do it.

JR Z9100S here too.

They're the best servo on the market for TC steering, but they were not designed for that. They are actually meant for the tail rotor pitch on helis where you really need that sort of combination of speed and torque at the same time. In TC, you might feel your car is twitchy, when in fact is your hand/brain not realising how fast this thing is. They are a smidgeon larger than a standard servo, and quite heavy, so might not fit everywhere. I eventually decided to move the steering servos in all my cars as close to the centreline as possible, and then there is no problem with using the JR. Otherwise, if it has to hang out the side, it might be.

Be careful though, you need a seriously fast radio to make use of its speed. Also you need to know it will draw 6A easily, so make sure there's a serious capacitor on your speedy's BEC especially if running boosted stock/superstock/mod brushless.

KO has a similar spec servo which I have reason to suspect is just as good but much more expensive for no apparent reason.

Hitec has some competitor servos in theory, but I wasn't impressed in the past by their product and gave it a miss.

There may be others I have no idea about.

Second choice Futaba BLS 551, low profile, light, good enough for the job, fragile, can buy two for the price of the JR.

Align DS610 in mines. Re-branded Savox servo (1258TG I think) and the center heat sink matches the AE anodized blue - which is ALL that is important.

I'd post a pic, but I'm still too new....

Spektrum S6070 (Re-branded Savox SC-1251MG) in my TC
It's very fast and has plenty of torque for a TC.

I use an ace 1015. 200oz/in of tq at .108 speed. Toughest servo I have used. Came from the D8t to the 2.0 to the ta05v2 now in the jrxsr. I have abused the hell out of it. Only draw back that I can see, it's quite a big sob.

Check Xtreme RC magazine. There's a trade in promo there. Order from www.savoxusa.com , type in promo code and away you go. Keep in mind there are only certain Savox servos this applies to and I was speaking specifically about the SC-1251 MG. $47 bucks including shipping from Utah to Florida. I believe it's limited to a maximum of 2 servos per customer.
Don't know if anyone noticed but IF IT'S YOUR FIRST ORDER you can get free shipping and a free t-shirt for any order over $50 bucks. My first servo I did this with. My second order I used the promo code for trade in but the budget only allowed me to buy one.
