Rudder Servo
 
Hey Gang,
I'm flying a GP Giles-202 1/4 scale and using Futaba 9001 servos all around. I'd like to use something a little more powerfull on the rudder that's reasonably priced. What do you guys like to use?

GP specify 65 oz.in all round, which fits the 9202 (70 oz.in) just nicely.

I think the 9001s are 54 oz.in, so are a bit marginal.

I've used 9202, 9204, and Hitec 5945 on rudder on a similarly sized model. If you will be really getting into the rudder, then the higher torque servos will make a difference. The 5945 felt like it could rip the horns out of the rudder, so maybe that was a bit of overkill.

Hey Phil,
Thanks, I know those servos are kind of light, but those are the ones shown in the instruction manual. Seem to be fine for now. I do want to really lay into the rudder, I think I might try the 9202

Wow
 
Hey thanks Dazzler,
That's 10 dollars cheaper then the Futaba, has metal gears and almost 10 more In-oz of torque. 76 as opposed to the futaba 69. That one seems pretty good!

Check this price:

http://www.servocity.com/Products/Hi...tra_speed.html

They're $5 cheaper at National, but you pay shipping.
www.nationalhobbbysupplyinc.com (this one and the 645mg isn't on the web page, but I stopped by and picked up a 645mg for my Lanier 540 Edge rudder for $35!)

They have Lustrecoat for $4.99 a can.

They only charge $299 for the Lanier 540 Edge.

Way cool.

Hi RickP, just wondering what voltage you're using. If it's 4.8 maybe you could just switch to a 6 volt battery and gain some torque and transit time. Just a thought.

go digital
 
I've used the Hitec 6 series on 60-90 planes. They're nice, but centering is not great.

Check out the Hitec digitals. How can you beat $55 for a digital servo?

I use one each on the rudder and elevator halves of a 20 lb, Brison 3.2 powered stinger. Good stuff.

Rick,
I have the same plane with a Brison 2.4
Try this servo HS-945MGJ from HiTec.
It is GREAT on the Rudder

hey rick:
i used the hobbico cs-70 servos in my gp pitts they are 106 in-oz @ 4.8 volts they are working great for me, you can get from tower @ 39.99 each & you can get 2 for 76.98, they are metal gear ball bearing hi torque, & i think they are the best you can get for this money. just my .02 worth

JD,
Can I just swap in a 6volt battery with no other changes?

Rick, yes you can just swap out the 4.8 for the 6.0, without any other changes. You get a little less flight time with equal mah pack compared to 4.8, so go with a high mah pack, like a 6 volt 1400mah. Daz...

rick:
check out hobbico hydrimax nimh 1650 mah, i flew all day & batteries still had enough charge to fly all day again

hey wadda know,
I found this thread after all. I know it's been a while but I'm ready. The 945 is like 80 bucks. The 625 is not in stock :-(
Any other Ideas?
I could just wait for it to come in.

The 645MG is actually a little cheaper than the 625MG at Tower, even though its the same servo with a little more gearing - slightly slower, but not enough that I can notice, plus it's all metal geared. I have over a dozen of them in use on 1/4 scale planes (Extras and Caps) and have not experienced a centering problem with them - trim doesn't change day to day or between flights.
