qustion bout servos

[550racer]

ok im puttin together a areo marine 20 tunnle hull and for the servos it says i can use a standerd race servo for the throddle and a high torque for the streering servo.. do i really need a high torque for the steering or would a standerd race servo work?

[aamick1971]

YES!!!!! USE AT LEAST A 95 OZ. OR BIGGER FOR STEERING. THOUGHS LITTLE OUTBOARDS HAVE MORE TORQUE THAN YOU THINK. I RUN A 110 OZ. DOUBBLE BALL BEARING IN MY TUNNELS.

now i can get the high torque in standerd size? the holes are drilled for standard size servos not the 1/4 scale ones..

[aamick1971]

yes they will or should be standard i have the GWS servos in my tunnels and they have a standard case. the one that i am using is GWS S03t 2bb go to www.gws.com.tw/ and should be able to find it, but any servo company should have them.

your url didnt work

[550racer]

im goin with JR stuff in myne i got a JR XR2 computer radio and goin to the hobby shop to buy the servos seprate..

[aamick1971]

thats good stuff too!!!!!!

550, sounds like your on your way.

As always, check ebay out and see what they have. A lot of good deals to be had if you catch them just right. Tower usually has good prices, but the hit is on the shipping.

Cant' wait to hear news about your boat also.

ill get some pics of the boat soon

I've used Hi-Tec 615 MG servos in all of my race boats. They're no longer made, I think that the new one is a 645MG. They'll turn a 7.5 OB tunnel with no trouble and the prices are reasonable plus they are a standard size servo.

i agree with ron. for the money, hitec's servo warranty, performance, and quality are hard to beat. go for the hitec 645MG, you'll be happy with it.

i feel that the same specification futaba's and JR's servos is slightly better quality/performance though, but you'll pay for it. futaba is just plain to overpriced i think. hitec is surely the best bang for the buck with their lower pricetag across the entire line, awesome warranty, and top-notch factory service and support. i've not had to use the warranty for any hitec servos yet, but i've heard only good things about their service department. airtronics stuff is good too. i prefer metal gears mostly especially in mini/micro size servos, but metal is not always necessary. it depends on your application. i feel the weight penalty for metal gears is not an issue in boats. some say that metal gears will start to give some play after they wear a little(compared to plastic gears), but i've not had that problem yet, and have yet to break them. i've broken many plastic resin gears though due to shock. this can happen with plastic gears regardless of the brand of servo.

if i HAD to pick just one brand of servos as the best all-round based on the models i've used, it would be JR stuff, but again more money than hitec. i have some JR digitals i use in my riggers for rudder. they've performed flawlessly for me with amazing speed, torque, and centering. but any $100 dollar servo should do that in my book. that's a silly amount of dough to pay for one servo, but i get them on ebay for less, and i like the reliabilty at the speeds we're running. i have one digital hitec that i've not used extensively yet, but seems to perform very well for the price.

btw, you don't need digitals. a quality same-spec analog servo will perform similarly. the benefit i've found with digital is the very accurate recentering and holding strength for rudder applications. the only drawbacks i see with digital is the "whining" sound they sometimes make when centered can become annoying for some folks, and they do draw more power from the receiver's battery than analog servos of similar speed/torque ratings.

on the other hand, i've used servos from other low-priced manufacturers with repeated poor results. off the top of my head, Cirrus brand and rebranded Cirrus clones would have to be my pick for repeatedly the worst quality/performance/reliability i've experienced. the "you get what you pay for" saying generally applies to servos.
