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.

I think I'll just start taping a 1/2 ounce of lead to
every servo for absolutely no reason

having to glue one back in when the servo unglued itself at a contest (Eloy

Used that method on my (used) Amethyst. It came with
those blue plastic frames for Volz servos already
glued. Made an Aluminum strap and screwed down my
lowly Hitec HS85MG's.

so you can get

Well... uh yeah... that'd be me. But I'm quite

don't like weight in the extremities of any of my

My question is who has done good, controlled detailed testing to see
which is lighter, glued servos or frames?
Assumptions and guesswork don't count. Real numbers please.
Many times we assume that doing something a certain way is
lighter/stronger but when real testing is done something different
So DP, there I was with both aileron servo gearsets blown out in my SPACEPRO

Thanks, Phil -
That is what I was thinking of, the inertia is the killer in when you
start adding weight at the end of an arm.
I don't know which installed setup is the lightest; I just thought it
was interesting that Daryl defended keeping weight down near the tips.

That's what everybody said, so a few years ago I glued the servos into a

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.
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.
