Re: [RCSE] Gluing Servos v.s. Servo Frames
If keeping a few grams out from around the servo holes improves yaw inertia by 5% then how can loading your tube spar with ounces ballast be a real benefit? First of all, the contribution of any added weight to the inertia depends on the square of the distance of the added weight from the CG. So adding mass at the tips is 4x worse than adding mass halfway out. Here's how much 10g of added mass (5g on each side) adds to the percentagewise inertia of a 60 oz Supra, versus spanwise position of the added mass: y=67: +4.0% at tip y=36: +1.1% at outer servo y=10: +0.1% at inner servo Second of all, what really matters for handling quality is not the inertia, but the inertia/mass ratio. This makes adding mass near the center even less consequential. Here are the effects of the 10g mass on the inertia/mass ratio: y=67: +3.4% at tip y=36: +0.6% at outer servo y=10: -0.5% at inner servo So adding mass near the tips is still quite bad. But adding mass near the center (inner servos, wing ballast, etc) actually makes things better, not worse. RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Gluing Servos v.s. Servo Frames
The frames work OK for ailerons but dont work that good, at least for me, on the flaps. As such if I have them available Ill use them on the ailerons.

Servo Frames Looking for opinions from people with more molded glider experience. Which is better? Gluing a servo directly to the wing using epoxy/balloon mix or gluing a servo frame and then mounting the servo in the frame. Does the frame approach cause more slop from servo movement or is it more secure? I like being able to remove the servo but I can do that with both approaches (granted it is easier with a frame). I guess I am looking for the most secure or precise approach. Thanks RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Gluing Servos v.s. Servo Frames
I can remember having to remove servos for gearset repairs and I remember having to glue one back in when the servo unglued itself at a contest (Eloy AZ). I can take the blame for all of the times this kind of stuff has happened, but when it happens, a glued in servo requires more effort to remove and replace than a screwed in servo. I have been making my own frames for a few years now by laminating spruce strip stock with overlaping corners by using the subject servo as a model, using thin CA as the glue, relieving where required for output arms and the wiring. Either screw the servo down thru the mounting flanges if using a wing servo or fab a small aluminum strap to hold the servo into the frame when using a conventional servo. These frames weigh next to nothing and can be glued into the wing with medium or black CA. Each frame takes about and hour to build up and for the frugal minded modeler, they are dirt cheap.

RE: [RCSE] Gluing Servos v.s. Servo Frames
I epoxy all my wing servos in but I do sand the case w/150 grit to get a bite on the case, I never use tape or heat shrink over the servo, just sand to a dull finish and spooge in. There are many photos of the spooge in instillation on my site www.f3x.com in the how to build section. Use good servos and land with your flaps up and they will not need fixing! If at a contest you did need to fix one they go right back in the custom molded spooge pocket with a finger wipe of 5 minute or a squirt of thick CA. Usually no re-trimming needed.

Re: Re: [RCSE] Gluing Servos v.s. Servo Frames
Daryl, To each their own, but my guess is that using the Greening Mounts or light ply mounts like the Volz servos come with can be done as light or lighter than gluing in with epoxy. I personally will take the extra time use a mount on any molded plane I do unless installing gear for someone else that asks me to glue them in. Gluing them in is a heck of alot easier and faster to do when installing gear.

That's the 2nd time that what I would consider a top flyer or top designer has talked completely differently about weight in a ship depending on where it's placed. Hmmm. I built the Drela Allegro-Lite last Fall, and for a 2-Meter built up ship, it will take as much lead as you can put in the belly - granted, it's a small belly, but still close to a pound. That in mind, when building the tips and tail feathers, weight was kept to a bare minumum, success measured in fractions of grams. The math supports it, if you care enough to fight through it, minimum speeds, mass and moment arms, headaches and sore eyes. All I really needed to hear (and basically hear again today) is that it affects how well your ship turns, how small a thermal you can work, the big things.

Wouldn't it turn a good performing sailplane into a slug int he turns? Wouldn't you want it in the fuselage around the CG? We are talking grams here and when was the last time you saw a servo mounted at the tip? I can appreciate what Mark D. is saying but . Mark Miller At the tail, and especially at the wingtips, the main concern is yaw inertia. For example, if you add 5g to each wingtip, you will... Increase weight by 0.7% Increase inertia by 5% So it really does pay to shave grams at the wingtips. As a reward you will get a -glider which handles better and signals lift better. -- __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [RCSE] Gluing Servos v.s. Servo Frames
That's what everybody said, so a few years ago I glued the servos into a new Extreme (5 min + lots of silica). That plane met an early...ahem...demise...and I decided to test the servo removal theory. Destroyed both flap servos...first tried twisting (that always works) and cleaned all the edges off the cases doing that. Then, tried the rod-through-the-root-and-tap method (that REALLY always works). Uh huh. Crushed the cases the rest of the way, and they STILL did not budge. Ended up having to pry and pretty much wrecked the skins doing it. No, never again. Even though I've only had to replace one servo in 5 years, I'll put up with the .15 oz added weight and use frames.

[RCSE] Gluing Servos v.s. Servo Frames
Looking for opinions from people with more molded glider experience. Which is better? Gluing a servo directly to the wing using epoxy/balloon mix or gluing a servo frame and then mounting the servo in the frame. Does the frame approach cause more slop from servo movement or is it more secure? I like being able to remove the servo but I can do that with both approaches (granted it is easier with a frame). I guess I am looking for the most secure or precise approach. Thanks RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Gluing Servos v.s. Servo Frames
I use volz servo frames when possible. No slop. I used goop to glue the frame in when there's no foam to eat. When I use just the servo, I run tape around it and glue it in. Definitely the servo frame is easier to use, especially when adjusting servo arms. You have to be right on when using the direct glue method.

Re: [RCSE] Gluing Servos v.s. Servo Frames
You have to be right on when using the direct glue method. Yes you do!! I've just finished a CR Climmax HLG. However, when I began I forgot to take off my foamie combat wing hat and began by just trying to slam it together. I glued the first servo very securely without thinking hard enough. I chose poorly and the plane has payed the price. Currently I'm a big advocate of the frames. Bill Swingle Janesville, CA RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Gluing Servos v.s. Servo Frames
Frames seem to be the majority vote. I think I will go with them on my next glider (I glued the servos in my Extreme last spring when I switched to molded gliders and decided then that there had to be a better way). Thanks for all the advice. Corey On 2/28/06, Tom Watson [EMAIL PROTECTED] wrote: Use the frames that Craig Greening offers. Perfect servo fit and easy install.

Re: [RCSE] Gluing Servos v.s. Servo Frames
Frames? I don't use them... they're heavy, they add weight. I can't remember the last time I had to change out a servo. 2 cents D __ Do You Yahoo!? Tired of spam? Yahoo!
