I'm looking for quality hardware for my new plane. I've been looking long and hard at the MK stuff.
I'm building a Creek Hobbies (1/4 scale) Sukhoi. I've already got the high torque servos on the way.
I don't ever want to run the risk of losing a plane due to crappy hardware (as most kits are shipped with).
I would be making 5 relatively short runs, from servos to surfaces.
I was thinking of the these:
---
P/R Set 24" x 5/32" Carbon Rods/Titanium 4-40
---
It appears that these kits come with 2 PRs and 4 fittings. Obviously I'll pick up more fittings as I don't need two long PRs but many short ones.
I'm looking at getting the MK control horns. I also would like to know what sizes you would recommend for ailerons, elevators, and rudder. The two sizes I am considering are 1" and 3/4".

I'll finish it all out with what seems to be the expensive parts; the clevises and adjusters w/bearings. I had my doubts but it sounds like they will probably outlast the plane. They can always be used over.....

Anyway, the BIG question is this. I read on the centralhobbies website the install instructions for the control horns.

The author suggested quite a lengthy process for cutting up the control surface to mount a dowel for these control horns. I do not have a drill press or many of the other luxuries that the author does.
My plane's control surfaces aren't that thick (save the ailerons).
Is is totally necessary to have a Dowel in the control surface for a 1.20 size model? Can these clevises just mount through the surface itself, with perhaps some thin CA to harden the mount point? (Epoxy for foam) Maybe a lightply insert on top and bottom of the hole?
The kit came with the regular Nylon control horns (two mini screws to hold in place). I want survivability but I want to have something fairly user friendly as well. At this point it seems that the MK control horns may be more work than just taking the chance with another form of standard control horn.
EDIT!
I just realized that I probably won't need any CF rods. The distances from the servo to the surfaces are pretty short... Therefore I doubt that I'll even need to use any CF if I can find a stiff enough 4-40 threaded shaft.
Anyone know who has the strongest, lightest threaded shafts. I would prefer the whole thing be threaded as it would be easier with the connectors I plan to use (above). I still need to know about the mounting of the control horns.
Thanks for your time.
