Status: offline 		I got a dumb question about servos.
Where should I use two futaba S3010 (nylon gears 90oz torq @ 6v) or trede them for hitec's 645MG (133oz torq @6v)for elevators and ailerons and the use one hitec 705 for rudder. where the lesser the torq servos should go and where the higher torq servos should go!
thanks guys!
Fernando

If you are going to set this bird up with 3D thows (35° to 50°) the servo's will see a large mechanical disadvantage. Even though your torque might be OK I would opt for a stronger gear train. It does not take much bumping of that control surface on the ground to damage the gear train, setting yourself up for a bad experience in the air.

Well, not quite anything with Karbonite gears--Skip the X475's on this plane. Even H.T. does not recommend them for anything over 8 pounds.

Why not 5 of the 5625's? You can get them to your door from Servo City for $46.75ea right now.

The Hangar (George Knapple)... a really good guy
(316) 941 4540

(you know you're in trouble when you have memorized your LHS' number by heart

Sure. The 5625 is plenty at 6v for rudder on this plane. If you have any doubts get the 5645 for the rudder---same price.

How about this, JR 125 mg SPORT
--- Looks like JR is doing something right. 5 of these with a pack of Dubro HD servo arms would do nicely on this bird.--the servo arms that come standard with these servos are very wimpy

"What if you need a standard sized metal-geared servo? Well then the ST125MG is right for you, as the ST denotes a standard size case, MG denotes that it has metal gears, and the 125 refers to 125 oz/in of torque @ 4.8volts. All eight JR SPORT servos feature universal connectors that will plug into major brand receivers and they still feature JR’s industry leading 3-Year warranty"

http://www.jrradios.com/Articles/Article.aspx?ArticleID=1497&tag=hwn2008

My LHS (Portland) has these in stock--they are $33.99 ea Have to believe JR is setting the price on these as this shop has Sky high prices on everything else.



I still think the 5625/5645 @ $47.00 to your door is a bit better value.
