<DIV><BR></DIV>>> On a foam sheeted wing do you think a balsa block
should be buried under the skins for the slot? Yes, and only balsa is needed.
No hardwood necessary unlike the bolt or MK method. This will save you a few
grams X 4. (On the ARC Brio, I slotted into the existing hard point. So in the
picture, the horn is glued to the balsa front cap, some foam, then the hard
point. I drilled several small holes in the horn for the epoxy to hold.)
>> I'm concerned with wear on a CF/wood sandwich... The ball is securely
attached to the horn in the same fashion as it's attached to the servo arm.
The aircraft ply will not crush under the minute torque of the 2mm bolt. There
is a washer between the ball and horn as shown in the NMP DARE packaging (I
found these rod ends just OK and will switch back to the MK for the next
project.) As there is no movement between the ball and horn, there is nothing
to wear. Some may cringe at the 'side loaded' attachment, but the horn is very
stiff and will not twist. Servo arm is the weak link in this install.

Subject: Re: [NSRCA-discussion] control horns Scott, On a foam sheeted wing do
you think a balsa block should be buried under the skins for the slot? Your
ball link connection doesn't look like it uses the conical standoff. Do you
have a detail shot of this? I'm concerned with wear on a CF/wood sandwich and
am curious how you solved this. Thanks, --Lance
