Ongoing E-flite DHC-2 Beaver ARF rudder horn problem
I bought one of the fresh new E-flite Beaver ARFs from Horizon Hobby last December and am now assembling it.
Up to now the assembly has gone according to the manual.
But when it came to installing the rudder control rod horn at the tail, a problem that many builders have complained about in the past cropped up once again. The rudder horn and the tailwheel post horn are IDENTICAL, not different ones as the manual says. The set screw holes are on the same side of both horns, rather than on opposite sides.
I've got a message in to Horizon Hobby asking for the proper rudder horn.
If HH does not respond (it usually does, but sometimes a problem seems to be too much for it to deal with) I will do what a previous builder did -- install the rudder horn on the rudder post upside down and farther up the post, aligning the ear with the clevis on the control rod. I will need to use a Dremel tool to extend the flat part of the post so that the set screw of the horn can bite into it.
But now ANOTHER problem with the rudder horn has cropped up, as it has before with other builders: The set screw is too small for the hole in the horn! It won't hold.
The solution to that, as other builders have said, is to roughen the rudder post with emery cloth and use epoxy to lock everything together.
Seems to me that this problem has been ongoing for six years and should have been solved by now. Thank goodness there is a solution, however kludgey it might be.
