ailerons-elevators control horns
 

Tom

In the 28% planes manual, you suggest a way that does not allow anything to show on the top surface (ailerons+elevator).

1) My LHS carry only Dubro and Sullivan control horns. May i use Dubro #866 control horns without the black molded washer and replace the 8-32 Allan bolt by a new treaded screw that i am gonna cut to desired length (invisible from the top)?

2) Should i glue the treaded screw into the hardpoint to eliminate any risks of hardware failure from a 50CC engine vibrations?

Is that way as safe as the one with the screw head showing on the top surface?

3) Should i order Rocket city 69D hardware??

Dubro 866 will work but you should shorten the plastic horn so the hole lines up with the hinge line.

No need to glue it in, just thread into hole drilled to 9/64.

RC #69d would have been a little easier.

Thanks
I think i am going to order the RC horns and trying to hide the top screw as described in the manual.

I would not abuse of your time but here is my last question: Which elevator wiring do you recommend me?
Should i install a 'Y' extension for 2 elevator servos connected to the elevator channel or connect both servos to RX and mix together elevator to gear?
