Where do I get some quality metal servo horns to use on my Synergy E7SE? I have JR DS8717 servos on cyclic and an MKS HBL980 on the tail.

The carbon plate over the plastic horn (per the manual) is a great servo saver, metal horns don't give much and the servo ends up paying for it when you crash.

Ron's is selling the nice adjustable JR brand ones that look great. I'd check those out.

I am using the ones that Ron's sells with the Futaba insert. I really like the ease of setup, but I am not sure of how (or if) they will be any better in protecting the servo in a crash, as that setup is really tight after the lock screw is tightened down.

What I do know is that they are really expensive, running $60.00 for a set of 4 futaba compatible horns.

I guess what I really like the most is being able to get a true 90 degree horn without the use of any subtrim at all. For my Vbars, I only added the necessary subtrim to the initial setup to get the onscreen center value to 0. From that point on, it was all mechanical adjustment on the links to get the swash absolutely level and positioned.

I highly recommend the Secraft servo horns
http://www.ebay.com/itm/like/252027...&chn=ps&lpid=82

In a crash, they bend and do not transfer the stress to the servo.

I use them on my Trex 700N, 600N & 600E with JR DS8717, DS8711 and a variety of Align servos.

I stopped using the typical metal servo wheels / arms after I stripped the gears on several servos.

If you cannot get or do not want the Secraft arms, then go with the plastic arms.

I used to stock up on the plastic JR servo arms to keep a few around just in case.

I personally use jr round horns with the carbon plate on my N7. I've never stripped a gear in a crash. The plastic horn takes the hit while the carbon plate keeps it ridget in flight.

Synergy servo horns
Yea I personally like the ones that come in kit. All geometry is right on and they will save the servos much better than metal horns. If ya want the metal horns go with V2 secraft arms

I use the large plastic arms that came with the 8717s in my 2 e7s. They are strong enough for hard flying but will give in a crash. I don't use metal servo horns on any of my helis. They are just too tough on the servos if you crash.

I have often wondered if the slip collar on the JR horns would slip in a crash if they were tight enough not to slip in flight. I am NOT gonna crash my Forza just to find out the answer, though.

I use JR plastic servo arms. Much cheaper to replace the arm in a crash than the gears. A very bad crash can strip the plastic teeth in the arm, I like that.

Thanks for all the suggestions... but I just noticed something. I was looking in the E7SE manual that I downloaded and Page 11 shows the detail of assembling a CF servo arm. Is that CF arm included with the kit and I just don't know it yet because mine hasn't arrived? or would I have to order it?
