Fellows. . .LSF023 here. I'm reading the various posts on servo mounting and looking at the ideas shown in websites mentioned and would humbly like to make a suggestion for another way to go that is easy, works in very thin wings, firmly mounts the servo and readily allows removing it. I direct you to the RDS website, http://www.proptwisters.org/rds2/index.html. From the opening page, click on INSTRUCTIONS to get into the MAIN INSTRUCTIONS. These were updated just today with NEW pertinent text, sketches and photos. Although what is in there addresses the all-internal Rotary Driver System, the part about servo mounting applies equally well to other installations. I think most everyone is overlooking something obvious, very simple and totally practical. Page to the 2 side by side thumbnail sketches and click to bring these up full-size. Look at what is referred to as "hat bracket" mounting in the left sketch. The base involved does not need to be more than 1/32" or so thick since no screws have to go into it to secure the servo! Instead the screws go into the rails on the base. I find a 1/4" wide rail, capped with ply so it won't split out, to work just fine. I can use 3/8" screws without worrying they'll punch through the skin. Bases can be made as wide as is deemed necessary to spread the loads on the skin. Rails can be as broad as you like and more than one screw can be used each side if you wish. Look. . .when overhead space is a premium, why would you want a thick base under a servo, except to run screws into? Using those auxiliary side mounts as come with the Hitec servos, etc. still requires a thick base for screws and there goes your overhead space if you aren't into $65-$100 super-thin servos. Since a center-mounted side mounting flange is a rarity in lower cost servos, hat bracket mounting is a practical option. In the website mentioned, page to the THREE PIECE WING section and look at the pics there that show such mounting in my GENIE wing, which is rather thin. I used Volz servos, but I tell you there was no overhead space for those neat, laser cut, dedicated ply bases Volz provides. . .NO WAY, so I did it my way! The highlighted word "GENIE" in that section is a link to my 12' span vacuum-bagged competition ship website. This ship is no wimp and requires very solid servo installation using the Rotary Driver System. Page to the MOLDED WINGS section for some suggestions regarding servo mounting in such wings using the hat bracket method. .025"-030" aluminum works well for the bracket. Size them so the screws cinch the servo down tightly so it can't move. I made up some little forms over which to size the brackets for servos I regularly use, rather than trying to individually eyeball and bend them to fit. ---------- > From: Jim Miller <[EMAIL PROTECTED]> > To: The Love Villar family <[EMAIL PROTECTED]>; soaring <[EMAIL PROTECTED]> > Subject: Re: [RCSE] Servo Mounting Article by Paul Ferguson? > Date: Saturday, October 07, 2000 9:15 PM > > http://bigglesworth.com.au/ssl/technical/servo_mounting.PDF > ----- Original Message ----- > From: "The Love Villar family" <[EMAIL PROTECTED]> > To: "Jim Miller" <[EMAIL PROTECTED]> > Sent: Saturday, October 07, 2000 9:14 PM > Subject: Re: [RCSE] Servo Mounting Article by Paul Ferguson? > > > > On 10/7/2000 8:39 PM, Jim Miller wrote: > > > > > Nevermind, found it... > > > > Where? > > > > -- Keith > > > > RCSE-List facilities provided by Model Airplane News.
