Al, i ordered 8 of your control horns the other day, i was planning on using a set on the rudder as a pull-pull, have you though about making a pull- pull horn for the rudder that would be one horn set instead of having to use two separate horn sets?

I agree with Henry.......I used gorilla glue to glue LE and TE once and will never do it again. I now use West Systems Epoxy.

I use a set on the rudder, Actually I have use this combo on a couple of our designs. We haven't really thought about a single horn on the rudder. One thought that comes to mind is the rudder thickness on different designs and the reference to the hinge line. With the two horn combo, spacing is a constant from the surface. With a single control horn depending on the rudder thickness you could end up with it being tight or far off the control surface itself.

By the way your order is going out today. We were at Perry for a couple days and just got back

Thanks Al, im in no hurry for the horns at this point, i still have to cut out surfaces and such. I do understand the point of the rudder thickness, i didn't think of that, i was looking at my rudder tray and was trying to figure what size arm i wanted and thought about if the rudder horns ... thanks again for the help and the great products!

Hey Al,

What size rudder control horns are we gonna need for the new Jtec/Radiowave 40% Chipmunk?

Would you recommend titebond, gorilla glue, or epoxy for sheeting the wings on the new Jtec/Radiowave 40% Chipmunk?

Do you recommend sheeting using a vacuum bagging system or weights for the new Jtec/Radiowave 40% Chipmunk?

(Sorry, just figured if we were going OT, I'd just get my $0.02 in)

Pete,

rudder horns: REAL BIG ones

glue for sheeting: Titegorillapoxy, its a new glue: its hard sanding but has good penetration and hard finish!!

We are developing weighted vacuum bags. They are heavy and really suck!! So if you spring a leak the weight will keep it tight!!

I like them answers Al!

Ready to balance after 3 months on bench.

Sitting like that it looks nose heavy. LOL

You Think!! LOL

Incidence all set. Zero everywhere.
Pic two, maybe leave a lil more meat on the doubler for the blind nut. Just a thought,

Hey Al or Jerry , plans show to cut elevators parallel to leading edge but wondering why most are going parallel to the spar, any benefits of doing one way over the other ? I'm ready to cut them out but wondering which way to go here.

Pardon me.. i meant, parallel to the trailing edge of the elevators .

Never mind, I got it figured out. Parallel to the spar tube.

Getting closer to flying.

What is the best method to fill pin holes in fiberglass ?
