GP Pitts servos
 

what servo do I need to use. Can I use 4 standards on ailerons? And how about 2 elevator & rudder?

You won't believe this but I had a Byron Pitts, a very long time ago, back before there were all these fancy servos. It had a Q42 in it and weighed 17 lbs. I had 4 - S148 servos in it, 1 for all 4 ailerons, 1 for the elv. 1 for the rudder and 1 for the throttle. For those of you who don't know these are standard bushing type servos with about 45 oz. in. of torque. I flew this thing for over a 100 flights and sold it to a guy who put another 100 on before it hit a post and scattered foam pellets all over the field.

I know you won't do this, but it can be done, so IMHO standard servos will work for everything except maybe the rudder, I wouldn't do that again, but it proves a lot of what we do today is overkill.

speaking of servos
 

why would you want to put a HD servo on the rudder first, wouldn't you put one on an elevator first, I don't know, I'm a newbie. :)

Overkill?
 

Hi DonM,

>>You won't believe this but I had a Byron Pitts, a very long time ago

Me too. In the late '70s. I had one of the first one's shipped. I sent them pictures of mine and they stole my color scheme for their ads....I was flattered. I had a Rossi 60/tuned pipe, with the byro-drive after dumping the low power gas motor I had in it. It actually flew really well until the pipe melted an elevator servo lead....styro-foam peanuts. Believe it or not, I gave the pieces to a friend and he glued it all back together and flew it for ages.

>>so IMHO standard servos will work for everything except maybe the rudder, I wouldn't do that again, but it proves a lot of what we do today is overkill.

I don't think I'll agree with you on this one. People today are generally doing a different type of flying than back then, also larger surfaces on the controls also make stronger servos a requirement. Personally I would go with the Hitec digitals 5925s(elevators and ailerons) and 5945s rudder. Definitely the best value out there on high-end servos.

I was thinking of 4 standard bb servos for ailerons and Hitec 605's for rudder and elevators. How about batterys. Should I use 5 cell 6V batterys. This is my first bigger plane so I appreciate the sugggestions. THANKS!

I'm still using standard servos on my Byron Eagle with a G-38 - no problems here!
