Default RE: Cedar Hobbies Zero G build thread

The landing gear went on easy enough. It seemed a little flimsy. I think the aluminum could be a little thicker or replaced with some type of composite gear. Nonetheless it worked out just fine initially.... If you hold the fuselage up against a light you can see the holes for the carbon tube exits at the front and aft, the holes for routing the fuel tubing from one side to the other, the location for the throttle servo (the locations for the elevator and rudder are obvious), the location of the slot for the two spar halves, and finally the hole for the alignment dowel on the wings. I went ahead and trimmed the covering back on everything and used my covering iron at about 250* F to seal everything back tight.

The elevator and rudder servos fix snugly into their holes. I had to trim some small pieces of wood away to make clearance for the cabling. After that everything fit very well. I will mention something I missed above, when I trimmed the aft hole for the carbon tube, I only cut the covering on one side. I left the other side intact as there is nothing feeding in from that side of the fuselage. Before I started on anything major I took several large lengths of cotton string and taped them together. Since I had the holes cutout for the carbon tube I fed the strings through so they were running out each end. These were very helpful in routing the servo cabling through the tube, through the wing, and from one side of the fuse to the other.

After I had mounted the elevator and rudder servos I turned to the throttle servo. I'm not quite sure what size servo this was intended for, but my standards were too large. The only micros I had were too small and fit inside the hole. Rather than build a bracket for the micro servo I went ahead and enlarged the hole to fit a standard size servo. This might sound like a PITA, but it only took about 2 minutes. Piece O cake! As far as routing the throttle cable, I've seen a lot of planes where a small hole was poked in the LE of the wing and fed into the radio compartment. I opted to try something different. Using a 3/8" spade bit, I drilled a hold through the frontside of the engine mounting area. Some may argue this weaken the engine area but I haven't had any issues yet. Even after drilling the hole there was plenty of wood to support the surrounding areas. Then, I used a coat hanger with a hook bent on the end to feed through the foam (it's everywhere, yippee!) and pull the cable through. This worked out perfectly as the cables ran right to the forward hole for the carbon tube, and right into the radio compartment on the wing. This produced a very clean install.

Next I moved onto the tail feathers. I sorta skipped a step and intalled this before the wings. Lucky for me everything measurement wise came out ok. I did a trial fit for the horizontal stabilizer and it was off-canter a bit. I trimmed the balsa and it was snug and aligned correctly. I like to use tape to mask off where the horz. stab. meets the fuselage. This way I don't have to use a black marker and mess everything up, and so after I remove the covering to glue it in place, any extra glue goes onto the tape and not the covering job. Works very well for me.
