The next step would be putting on the canard tips. But before I could do that, I had to make a slight detour. The wiring for the lights will along the inside of the canard through holes that were drilled through the foam core when I was down in Florida. But at the time, I didn’t know how big the connector was. Turns out it’s just a little larger than the hole. So I had to make a new, slightly larger drill bit using a piece of 1/2″ electrical conduit. I cut a saw-tooth pattern in the end and twisted it through the existing holes and enlarged them a bit.
Canard end before.
The first step is to make a cutout for the elevator counterweights. These weights counteract the weight of the elevator to eliminate downforce caused by the weight of the elevators. The counterweights are recessed in a pocket that I have to create.
First I mark the location of the counterweight pocket.
Then cut it out.
Then glue on the canard tip. The tricky part here is to make sure that both tips (left and right) are symmetrical. For this I used my laser level again. Once I had the canard level, I shot the laser across both tips and adjusted until they were level. This side gave me some problems so I had to “persuade” it with a clamp until the glue set.
This side only needed a little tape to stay in place.
This is were I discovered a minor glitch. When I was drilling the holes for the screw that attaches the elevator to the torque tube, it turns out that my alignment was more precise than the canard itself. As a result, the elevators are not perfectly aligned. I didn’t notice it before because there was no reference. With the canard tips on, it was obvious that one elevator was lower than the other. Not a huge problem. I just need a new aluminum bushing that I’ll redrill. So until I get that, I’ll put the remaining canard tip work aside.
