RedWing MX2 Build
Finally I found time to start working on the MX2. I am really enjoying this build since this model is such a well engineered kit. I want to take my time putting together this kit and try to report as much of the details as I possibly can. So far today I have just finished the wings. It took me about some five hours to complete that task, and that was because I waited 1 hour for the aileron horns epoxy to cure and took lots of photos. I didn't bothered with using the hot iron since I didn't found a single wrinkle in the wings covering. By the way Tim was so nice to include a set of 18 gauge wire extensions set and the kit comes with all the necessary safety clips. I recommend this optional extension package when ordering the kit. It will save you a trip to the hobby shop, and they are cut to the correct size.
All the horns on my kit are of the FG type and they fit perfectly on their slots. Make sure to lightly scuff the surface of the horns that will contact the slots for a good solid bond to the FG. I prefer epoxy for this job and always install the ball links before gluing the horns to prevent them from misalignment, make sure the ball link bolt is aligned with the hinge line. A loose horn could be catastrophic, believe me I learned that the hard way. I prefer the aluminum horns for security, other folks don't like them because of weight. Aluminum horns have been proven to be very secure and Pattern ship jockeys that's all they use and the weight difference is negligible.. In any case FG horns are perfectly fine as long as they are properly installed.
The only problem so far were that the small servo wheels on the Power HD 150MG's servos proved to be a tad small for the provided aluminum arms. I had to use the large wheels and modified them a bit. A quick work with my jig saw and a little sanding with a Dremel sanding drum reduced the large wheel to the correct size. In the process I polished the arms edge back to the bare aluminum just for kicks, I think they look cool this way (see photos). Found out the arms need to be drilled with a #40 Wire Gauge drill bit to accommodate the Ball Links bolts. Since I was working with the aileron arms I decided to finish all the other servo arm assembly and lo and behold and to my surprise all other three Hitec 645MG's servos wheels were a perfect fit, even the holes align perfectly. Please note I always install a washer on the ball link to make sure in case the socket decides to separate from the ball.
I started on the elevator assembly but I am getting a bit old and I need my sleep so I will continue tomorrow.
