Yesterday started with seeing what Peter had down, which was installed the hinges for the ailerons onto the trailing edge of the wing. This involved making a two toothpick sized wholes per hinge as well as drilling a hole for the toothpick into the hinge itself. Then the hinges were glued inside the slot with the toothpicks pushed through the pre-drilled holes. This was done to provide greater strength to the hinges to help prevent them from disengaging from the trailing edge of the wing during flight. Upon my arrival to complete the process I cut off the excess toothpick ends and then sanded the ends to be flush with the trailing edge sheet.
This day involved the most sanding I’ve done in a while as I touched up spots on the fuselage in the fin areas and then in rounding the leading edge of the stabilizer, seen in the image at the top of the post.
The fuselage of my aircraft is going to be white, like on my previous build. Essentially I am trying to standardise my colour scheme so no matter which aircraft I am flying top and bottom colours will be the same (exception to this may be when I get into real world models, i.e. Thunderbolt or P51 Mustang, and want to be true to the aircraft. That is why, seen below, I did the trailing edge of the fin in white and then slit the covering where it covers the 3 hinge slots. For simplicity due to the stab/tail design I ran the white right up and over the top. This pieces still requires some touch up before proceeding with covering the tail end.
On Oct. 15th I started by covering the portion of the top of the wing around where the holes for the wing bolt down bolts are, seen above. For simplicity I ran the yellow right to the trailing edge of the wing. Once covered I cut out the fabric covering the holes.
After that I started covering the ailerons, specifically I just got a single tip of one of them done. This is a very meticulous task due to all the angles. On this one I folded the edges around to the flush surface, which I’m not please about so for the next 3 ends I plan to wrap the edges around and then fold down the bigger pieces onto the top and bottom of the aileron.
In order to do all the folding a lot of cuts are required for all the corners. You can count them in the image. Looking at making at least 5 cuts. Sometimes an additional cut or two are required if one or two are off or the covering is being obstinate.
On Oct. 14th I continued covering the wing. This included covering the wing tip, seen below. This involved curving the covering around the outer curve of the tip and then trimming the excess at the top as well as along the straight edges (inside of the tip) to get a cleaner finish. I did my best to line the bottom of the green with the bottom of the green on the trailing edge of the wing.
In order to prep the wing for covering the bigger surface areas I had to do some smaller covering jobs to help ensure a seal is made to help protect against wind peeling back the covering or fuel/debris getting into joints. These were done in orange since the bottom of the wing is going to be orange like my previous build.
In the featured image you can see where I covered around the wing dowels. This involved cutting a rectangular piece, puncturing a whole for one of the dowels and then putting it in place to measure where the next hole was needed. Once the holes were made the covering was placed over and ironing down started in the centre (rolling over) and worked my way out to the edges.
Below is a close-up of the covering around where the wires will come out of the bottom of the wing for the control surfaces. Need to make cuts at the corners to all the covering to fold over, sealing the corners, and iron down properly. The covering was cut out out to expose the openings where electronics will pass through.
I had another hiatus from building and finally got back to it again on Sept. 28th which debuted covering of the aircraft! That’s right I have finally got to the point where I can start covering. I am planning on following a similar color scheme as my previous aircraft.
This session saw the start of covering the wing, specifically the trailing edge in green, seen above. This involved measuring and cutting a few pieces of covering and ironing it on to the trailing edge with some excess to fold over each edge. In the middle where the metal wire is for the aileron controls required some extra ‘fiddling’ to get the covering to fit right as needed to make a hole in the covering, slide the wire through and then figure out where the other hole needed to be made. Then once done slip the wire through holes made in the covering and iron it to the wing.
On each end of the wing where the covering is folded over additional cuts were required to get a better look.
On Aug 5th I did a fair bit of sanding touch ups on the wing, ailerons and fuselage. This included sanding paste where balsa blocks meet the fuselage, seen above. As well as some careful sanding of the paste on the trailing edge sheet and ailerons, seen below:
Yes, I know these last few posts have not been all that detailed; however, due to circumstances I am months behind on posts and am taking today to catch up so I at least have some sort of track record of when I did what. 🙂
On May 27th I saw some of the work Peter had done on the aircraft and put in some of my own work. Peter had the keel glued to bottom of fuselage, seen above as well as the balsa blocks for the engine mount in place and formed with paste applied to fill the gaps. I just had to do some more sanding of the touch up paste applied to give a smoother transition.
I worked on making a template for where the servo cables for controlling the ailerons are going to come out of the wing, join and then connect within the fuselage.
On May 5th I glued the fin to the tail of the fuselage. I used some triangle stock to run along each side of the fin. This is glued to both the fin and fuselage to provide added support to the fin. Made sure the triangle stock was a bit longer on each end to give me some to work with later for the tapering, etc.
Everything was then clamped and mostly pinned into place while the glue dried.
On May 4th I worked on the wing and tail of the aircraft.
Seen above I worked on sanding the leading edge, specifically the wing tip corners to get the desired taper.
The fin of the aircraft is composed of two pieces, front and back. I started by sanding off the ‘burnt’ finish from the laser cutting and then glued the two pieces together, pinned them to the board and placed weights on top to hold everything in place while the glue dried. This is seen below, the wax paper is to ensure nothing gets stuck to any glue that oozes out that shouldn’t.
