RE: JUST ARRIVED -- SOMENIZED YAK-54, 49" ELECTRIC
Hi Guys,
Well I decided to continue with this build despite the low response in hopes that someone who is thinking about such plane will find this helpfull. I like to emphasize that this plane is designed by a #1 Pilot and RC Airplane designer in world and there is great deal of attention being paid to details that effect the performance such as weight, etc. I suggest avoiding any unnecessary steps that would inadvertently increase the flying weight of The YAK. Take extra care not to use the fuse as fulcrum, leaning against and wedgeing against it. It will break.
I started the build by inspecting all the pieces, trimming out all the fuse and wings and tail openings. In doing that I used my iron to go over edges and all over the ultracote. I used the lower setting on my iron (see picture). Once that is done you should end up with 3 slots on the left side and 1 on the right for the tail surfaces (view point from nose).
That took about ½ hour.
Next I started on the tail section by locating and adjusting all the control surfaces hinges for the tail. Checked the depths, inspected travel. I then moved to glue the stab. To ensure the parallelism with wings, I used a measurement method as follows. Measure front side of stab 7” from edge and mark and rear side 6 7/8” from edge and mark all four sided. Place the stab in fuse and line up to the marked edges and that should be perfectly parallel to the wings. You may also need to add shim to either side to ensure perfectly level stab to wing. Per manual you can compare that with wing tube in place. Once stab was aligned, I used thick CA to attach to fuse. Following the manual was easy on the rest of the tail surfaces using thin CA.
At this point I was 2 ½ hours into the build.
Signing off for now,
Jason
