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?
Rick

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
Rick

Rickp, take a look at this servo for your rudder!! Daz

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!
Rick

Check this price:

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.

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?
RP

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.
RP

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.
