The kit was indeed bought from Sandor (Digitech) some years ago. I think at that time you could order every type of plane in the Red Bull scheme at c-arf, they also had the yak55, flash, etc... in this scheme.
I installed the aileron servo's. The linkage is a 150mm M3 threaded rod, as stated in the manual, but the kit was supplied with a 120mm, so i had to get my own.
Now i want to install the flap servo's, looks difficult 'cause they're hard to reach.
The manual says the flaps should be supported by phenolic hinges. My kit does not have them installed by factory, although the manual says only the first kit were shipped without. My kit sure isn't one of the first, as it is an Ultra Lightning....
In the kit i can only find 3 half hinges, (top right in the pic) and i need 8 pieces to support both sides of both flaps....
Has anyone pics of how they solved this, maybe i can use a robart hinge?
