Title: Flap horn mounts ?
Post by: Rob Killick on June 19, 2006, 11:27:22 PM

I'm feeling quite talkative tonight , so here goes :)

Another question concerniong Brodak's "Oriental" ...

The plans show the flap horn ( elevator horn , as well ) as a pre-bent wire , without any bearings to hold it securly to the wing trailing edge .
I've noticed in some RSM kits , that the flap horns are left to be bent by the modeller after the nylon (?) tubes are installed  on the horn , which in turn are secured to the wing trailing edge by cloth hinge tape .
I'd like th flap horn on my Brodak kit to be secure as possible , so I'm begging for some ideas  :!
I will use barrel hinges throughout the kit an was wondering if notching the leading edge of the flaps (at the hinge location) to close the flap / wing gap is a good idea ?

Thanks a bunch !  <=

Rob: Thats how I do mine, I use a Groove Tube (tower sells them) or sharpen some K&S tubing the same diameter as the control horn and cut a groove to where the horn leg goes into the flap/elevator. The horn is then epoxyed into place as usual.

 If they are already bent, find some ballpoint pen springs, and you can just slide them on. Have to be a little careful gluing though.
