Im putting together a gp pitts and think Im gonna go with just two aileron servos. Does anyone have a suggestion on which ones to use. Futaba radio buy the way.

Thanks in advance,

I have to say -if you are powering this for ANY kind of serious aerobatic performance, and you want accuracy, go with FOUR. It is too easy to do the way they've designed the wings, and you can "Y" both sides together to make it work with only two channels...
There is a LOT of benefit from having the extra servos.

That being said - your question was "what kind?"...if only using two get some VERY strong, probably coreless, 2 bb servos. The flavor is up to you...Futaba, JR, Hitec, Airtronics, Cirrus, GMS, Multiplex, and who knows what else.

What you need to be *happy* with the Pitts is ailerons that respond immediately (speed), center the same every time (deadband precision and centering), move to the same amount of travel (gear train/potentiometer), and HOLD the control input through the performance range (torque).....

My choice - for CHEAP - GWS BP105's (2bb, metal geared, coreless, 110 oz) Not the fastest, and centering isn't as good ast my BEST choice - JR 4721 - 2 bb, nylon gears, coreless, fast, about 110 oz. If you have LOTS of money - four DIGITALS, pick your flavor.

I set up mine with 4 Hitec 422 servos in the wings. If you want to go with only two then Hitec 645's will be fine.

Hi..

I*m allso looking for some advice regardig servoes in my Pitts. I*m only using Futaba stuff. What do you think of this:Rudder\elev:9202 aileron:9001*4(with added bb)??

Will the 9001 be up to the task? I* using a ZDZ60, I beleve in throttle managment and are not going to fly this baby to the extreme.

I used four hobbico cs71 in the wings & four in the tail, I think they are the same as the hitec 645, they are 110 oz/in b.b. metal gear servo's, work great. about $38 per servo @ tower. I think they have discontinued the cs71 & replaced it with a cs70. I am using a g-62 for power with a 22x12 mejzlik prop.

I used 4 605 in the ail and 1 5645 digital on rud. and 2 625 on the ele. the throttle is a hs 85 mg micro mounted in the engine box. All servos are hitec. Engine is brison 2.4 and plane is 15.5 lbs.

good combo in my book
Happy flying
