Re: [RCSE] Wing Servos
Thanks everyone for your answers, I will remount my servos and I'm sure they will be secure.

[RCSE] Wing Servos
<> Two ideas that worked reasonably well: 1) Goop has great grab to anything but will dimple the foam - probably because it's captured under the servo and the VOCs hang around long enough to hit the foam a bit. Epoxy a thin piece of ply in the bottom of the servo well and then Goop to that (sparingly as in the previous post), or (better approach) 2) Switch to Gorilla Glue. It will swell a bit and won't attack the foam. The servo will be well seated once it's set. Seems to have a good grab to most plastic surfaces. Once set (~ 4 hr.), the excess that swells out can be trimmed with a single edge razor or easily milled down with a Dremel (thanks to Bob Peck for pointing this one out). I'd suggest putting a band of masking tape around the servo before using the adhesive. That way the servo can be extracted from the tape without taking a hunk of foam out of the wing. - Dave R RCSE-List facilities provided by Model Airplane News.

I cut my cores at 6" which makes my thickness just over 1/2". That still leaves my .47" th. servo hanging out the back. On this version I am going with outboard servos. I am already committed. I have been round and round with moving servos inboard for CG purposes, cable linkages, torque rods, etc and I just decided to go the most direct route. Ie; outboard servos. I figure that if I like the way it flys I will tweak it and build another one. :^) Chris RCSE-List facilities provided by Model Airplane News.

[RCSE] Wing servos; Top or bottom?
Hi There, Which side of a wing is it better to have a hump in the airfoil? The top or the bottom? I am building a C07 HLG that has a RS004 airfoil. The servos are flush with the spar but stick up towards the aft part of the wing. I plan to make covers for them. The C07 HLG is at http://www.zanonia-flyers.de/. I wanted to try building something different and I thought that this looked cool. Thanks, Chris RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] wing servos
According to Horizon Hobby's and Hitec's web pages: the JR 341: 32 oz/in torque .63 oz JR 331: (a little cheaper than the 341) 42 oz/in torque .63 oz HS-80: 31 oz/in torque .62 (.76 w/metal gears) HS-81: 36 oz/in .59 (.67 w/metal gears) HS-85 (has a top ball bearing): 38 oz/in .7 (.84 w/metal gears) (I'll let Karlton hawk the Multiplex stuff) you can get all the rest of the info from: www.horizonhobby.com www.hitecrcd.com hope this helps, kevin At 06:15 PM 7/30/99 +0200, Juan Cifuentes wrote: >Hi >I am building a DAW 1-26 (2m.), and the instructions recommend JR341 >servos for the wings.

[RCSE] wing servos
Hi I am building a DAW 1-26 (2m.), and the instructions recommend JR341 servos for the wings. They are expensive and not easy to get over here. Does anybody know of the equivalent size and torque in the Hitec/Multiplex range? TIA Juan [EMAIL PROTECTED] RCSE-List facilities provided by Model Airplane News.
