    Engine looks terrific. But I think it would benefit from push rods and a wiring harness. Since you’ve gone to so much work up to this point to dial everything in, you might want to add that additional detail to enhance the what you’ve accomplished so far. @gblair. Go for it.

    The engine looks really nice, George @gblair
    Even spending a little time behind the bench can already be satisfying,

    Thanks, Carl (@clipper), Spiros (@fiveten), Eric (@eb801), and John (@johnb). Got some stuff done today. A new F-86? I'm still happy with the Monogram F-86. :o)

    I love the look of detailed radials. They really stand out on those planes where they are visible. But they can be tedious as well. I have to switch back and forth between inlines, radials, & suck-n-blows just to keep my sanity.

    Today was wing day. The two resin pieces had to be perfectly placed in each wing for this to work. I took my time gluing the resin pieces into the wings, hopefully insuring that everything will fit in the end. I spent about an hour test-fitting the wings and adjusting the fit in the fuselage. Once these are glued, here is no going back. I finally was ready to commit to glue and, of course, it wouldn't go together like the previous 32 dry runs. I finally got the wings glued, but then noticed that one wing was noticeably lower than the other. A few yards of masking tape will hopefully hold everything in alignment until the glue dries. I have my fingers crossed.

    I did some frustrating work on the engine. The Monogram kit was one of their "hi-tech" models with a small fret of PE, which included a wiring harness with plug wires. The ring wouldn't fit around the engine that I have, but I cut and installed each plug wire. It took another fun hour to install the push rods using round plastic strip. Looking at the photos, I have realized that the plastic was too big in diameter. I don't know if I have the heart to go in, rip them all out, hope nothing gets damaged, and then replace them all with smaller plastic. Another decision for tomorrow.

    Great progress with the wings. But I agree George @gblair, the push rod tubes look way out of proportion. Should be an easy fix don’t you think?

    @gblair - Progress is not always linear George. I do agree with Eric though, the plastic rod on the engine feels out of proportion. Once it's fully assembled it may not be too noticeable, but you'll see it every time you look at the model. I'd make the adjustment... just for my own sanity. I doubt anyone else will notice if you don't point it out to them.

    I believe that whatever you decide to do is the right answer. Personally I’d place the cowling around the engine and then see what it looks like then go from there. If they still look too big then I would suggest doing them over again. Like the others have said, you will notice the oversized pushrods every time you look at the model. This might make you think less of what you’re doing with the finished product. That would be a shame especially since you have gone through the extra steps to make it look so perfect, (which it does by the way).

    If you start taking the pushrods apart you might actually cause problems with breaking stuff and that’s not good. So if you start taking it apart tread lightly and be careful. There’s a product called CA debonder and I have used it in the past for fixing mistakes I have made in my RC planes. It might be worth looking into if you used CA glue to assemble the engine. You can neutralize it later so the glue can stick again on your next time.

    The choice is yours and in the end you should be happy with it. This could be a case where a close enough match is good enough. You will figure it out in the end, I’m sure.

    I’m totally impressed with your attention to details and the aftermarket stuff you have added bring this one up to (and over) the top.

    I’ll be looking for the next installment.

    Thanks, Spiros (@fiveten), John (@johnb), gary (@gwskat), Eric (@eb801), Brian (@brithebuilder), and Louis (@lgardner). Thanks for your comments. This model has turned into a quest, and I reached a point where I needed to take a break. The quest came in the form of problems with the canopy. It all started with the windscreen. The Kingfisher had a tube gunsight that extended through the front plexiglass. The Monogram windscreen has a slit for the gunsight that extends halfway up the windscreen rather than the single hole that should be there. I had a vac canopy from Squadron that is designed for this kit which would solve the problem, but I have never used a vac canopy before. The windscreen and the front sliding portion of the canopy were formed as one part, so I cut them out together. Everything was looking good until it was time to get down to the final shape. I was using a fairly fine sanding stick so that I wouldn't remove too much, and I managed to remove a portion of the frame on the sliding portion of the canopy. I couldn't think of a way to fix it, so I cut away the sliding portion and used just the windscreen. After having so much trouble shaping the forward canopy, I decided to use just the vac windscreen and use the kit plastic for the rest.

    I tried my hand at creating some masks on my wife's die cutting machine, but I only mask that fit was the front panel. I masked the rest with tiny bits of tape. I tried various glues to cement the windscreen to the model: white glue, canopy glue, styrene glue, Gator Glue, and super glue. In the end, none of them would firmly attach the vac canopy to the plane. By this time, I was starting to realize that this endeavor had become a soul-sucking operation. At the same time, my 3D printer decided it wasn't planning to correctly print things, and them temp here in central Texas went up to 112 plus. So, I decided my Karma was out-of-sync with the universe, and I needed to take a break.

    So, I took a week off. Then I built a really old model and stuck it in the display case. Then I went and looked at the canopies that all needed masking, and I took another week off. At this point, I realized I had become too dependent on pre-made canopy masks and decided to jump back in.

    First, I cut a piece of clear plastic that would fit in the slot in the front windscreen. I glued it in place with liquid cement, and then polished it on both sides using ever finer grits of sandpaper, and finally some paste metal polish. All of the clear parts had been floating unrestrained in the kit bag for 50 years or more, so there were lots of scratches. I polished the scratches out using metal polish, and then all of the pieces (including the front windscreen), were given a bath in some nice, cool Future. I wanted to let them dry for 24 hours before I masked them, so I finished out all of the last parts on the interior, including the seat, the stick, the gunner's seat, and the rear machine gun.

    Feeling better about things, so masking will be soon. Probably won't get much done next week. I live a couple of hours from the location of the IPMS National Convention, so my wife and I have a room and we plan to spend a couple of days in San Marcos at the show. I don't build for contest anymore, but I have never been to a national show, so time to check it off the bucket list. I still have a couple more models I want to do for the group, so I need to get moving.

    I get it why you need to take a break. I had to stop the Otaki Hellcat I’m 95% finished with for this GB and take a deep breath. Your Kingfisher is going to look superb when you reach the finish line. That cockpit is terrific! @gblair. Keep on pushing forward. Once you plunge down the rabbit hole, it really does turn into a “quest”, doesn’t it?

    Thanks, Eric (@eb801). I picked the plane that has a ton of glass for my return to making my own masks using masking tape. I tried making my own masks on my wife's die cutter, and they all fit, sort of. I may try to create my own masks with my wife's machine again, but on something with a lot less glass.

    Looks like taking some time off from your Kingfisher paid off, my friend @gblair! Looks splendid so far! Keep pushing!
