Default Newbie - Which 55 oz servos would you suggest

Hi all - I'm getting ready to launch into my second kit build. I am going to bash a Sig Four Star 120 into as scale as possible AirTractor 602. The plans call for 55 oz servos.

What would be a good JR compatible servo set in this range? I can't afford the $100 per servos

I am also going to try to put Fowler Flaps on it since this is also to scale. Any ideas about servo size here.

Thanks for the advice - always appreciated

Here is what a beautiful scratch built scale version of the AirTractor should look like.

The hitec 5 pole 545 is a good precise servo that falls in that ballpark at a moderate cost

You may want to consider the Hitec 5475HB instead.

Dual ball bearings (the 525/545 servos have case top BBs only), heavy-duty resin gears, digital accuracy & holding power.

The best part? Only $5 bucks more per servo.

If you want a cheap high torque servo try the Hitec 605 that has a lot of torque and is pretty cheap ($50 can or about $30-$35 US)

The part # is HITHS605BS

Here's the stats:

Dimensions: 1.6 x 0.8 x 1.5 in.

Weight:1.73 oz

4.8V Operation
Torque:77 oz-in
Speed:0.16 sec/60

6.0V Operation
Torque: 91 oz-in

The Hitec HS-605 is a High Power Servo featuring Surface Mount Technology and dual ball bearings. Available for Airtronics, Futaba and JR Propo, with resin helical gears or with metal gears.

Default Servos for 4* 1.20

Forget the analog servos. For the same price or a few bucks more get yourself some digitals.

If you want some powerful servos for your plane, try the JR 811 Sport digitals at about $50 or the Hitech 5475 sport digitals at $35 from Servo City, free shipping. The Hitechs come with a nice, red, X-type control arm. One side is regular thickness for clevices and pushrod connectors and the other side is heavy duty thick for the bolt on stuff.

I have 4 of each and after the servo moves, you can't turn the wheel-the holding power has to be felt to be believed. I think the JRs are slightly faster, but the Hitechs are supposed to be a little stronger. You can't turn either one under power. A buddy and I have tried with both hands. We swear you'll rip the gears out before they move.

Default I think I'll go with th 5475's

Hi all - thanks for all the responses. After looking at your responses and then having a chance to look, touch, feel, smell I'm getting happy just thinking about them...

I decided for the price, and what appears to be an excellent JR compatible servo that the 5475HB's will be a good fit.

Want to also thank the guys up at TNT for some great help yesterday and a really nice landing gear (among other things).
