<div style="margin: 0in 0in 0pt">Hey Fellas, I sent an e-mail to JR, Spectrum, Futaba, and Hitec to find out what their recommendations would be for servos for the Byron 51. These are the responses I received. The Hitec flight package is around $1000.00. Seems a bit high for a flight package (not including any batteries) but I have no clue these days as to what is in the market and just how much I will have to spend to safely fly my 51. I don&rsquo;t want to take the cheap route just to save money but I also don&rsquo;t want to throw money away on something that is just overkill.</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">Would you mind giving me your opinions and recommendations for what I want to accomplish. The servo world has just gone off the edge and I can&rsquo;t seem to find the answers I am looking for online. I didn&rsquo;t realize so many different options existed. This is what happens when you take 15 years off from flying RC.</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt">Thank you for any information you can provide.</div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"></div><div style="margin: 0in 0in 0pt"><span style="font-size: 12pt">JR SERVO PACKAGE</span></div><div style="margin: 0in 0in 0pt">We would recommend the JRPS791 retract servo and no less than the JR</div><div style="margin: 0in 0in 0pt">DS821 for the control surfaces.

Just one point, anyone who recommends a standard type servo for mechanical retracts is not quite on the ball.
Too many ways to come undone, and the saving on the servo's will probably cover half the cost.
And if your going to this expense, may I ask, why are you not putting good pneumatic retracts in her?

Are you using a simple Rx, or are you running one with more complex features, such as servo balancing, in which case you don't need the programming capabilities of the servo.
Do you really need digitals on the flaps? Metal geared?

They quote a pretty hefty servo for rudder, which might be fine on an aerobat, but in my experience the warbirds are pretty light on rudder forces, and rarely need metal gears. And does it need to be digital?

Ailerons and elevator I always go for the best I can afford, and always metal gears in ailerons.

Throttle, never metal gears but I would go for bearing rather than bushing, but this can depend on the type of linkage you have to the motor, ie: a bowden cable saves a lot on your servo but solid wire linkages are much harder on your servo.

Just some thoughts to throw into the mix.

Those hitec servos are overkill for a warbird IMO. The spektrum servos they quoted you look good and the JR 791's are very good retract servos.

<div style="margin: 0in 0in 10pt">Thanks Mike and Tom, I am using <span style="line-height: 115%; font-size: 10pt">pneumatic retracts</span>. The retract servo needed for the retract system need is a 180 degree. I think the Hitech is overkill but I have been out of the rc world for a few years and I was shocked. I also agree with your assessment as to requirements for servos in this warbird but you never know what might crop up in a different technology state 15 years down the road.</div><div style="margin: 0in 0in 10pt">I am very glad you agree with what is reasonable for my needs. The only point I might disagree slightly would be the rudder servo. My reasoning would be moving the servo around why the plane is stationary would cause a lot of drag but you guys should know better than I do on this point.</div><div style="margin: 0in 0in 10pt">Thanks guys, this gives me a better direction to approach. It&rsquo;s always reassuring to hear from the guys that have been at this a while. I was starting to get lost in servo hell.</div>

Why not go over to the Servo City web site and look at the specs on the servos they sell and choose the ones you would like. One year I got all my big servos from them during one of there sales for under half price. I just fell into that while I was doing a search.
