Thanks to Frederick Boucher's excellent photos I was able to figure out several errors I'd made in the rear section of the aircraft, and I've now corrected these as shown. Thanks so much for your help!

I'm still not quite sure how the roof of the bomb bay is constructed, but I'm starting to have some better ideas and hope to be able to confirm the construction details so I can finish out that area.

Here's the latest showing the corrections I've made.

I've finished the oxygen system. Next up will be to finally complete the bomb bay which will include scratch building the radio compartment over the wings as well as do the fuel system. I won't do any tanks since those are either inside the wings (already completed) or in the space which the wing attachments are. But I plan to add the hoses, lines and valves which would either be in the radio compartment or bomb bay.

Time for an update. I've mostly finished the intercom wiring and the radio system installation. A large part of that has to wait until after I build the compartment over the bomb bay. I've also installed the flight suit heater system and the aux generator and batteries as well as two hydraulic reservoirs and the nose gear door retractors. Next up will be the oxygen and fuel systems and then on to the bomb bay which will finally allow me to permanently install the flight deck and nose wheel assembly.

Tom,

I am in awe!

Splendid work. So where did you get these - scratchbuilt? I think this is a hydraulic/fuel system:



It's a hybrid. The main piece you're looking at in the photo is from the Eduard PE set with some scratch built pieces to give it more depth. There's another similar PE piece for the LH side of the aircraft. But these pieces go only in the bomb bay section, so I scratch built some additional pieces to go into the area under the flight deck. I didn't make as many lines as there actually are according to the photos, but only enough to match the PE lines.

Thanks for all your kind words. After I bought the aftermarket radio set available, I realized that there were quite a few items not included, and it seemed silly to put a few in and not the rest, so I resorted to scratch building. The internet is so great for research, as I was able to find not only the flight manual which described all the items along with pictures, but additional photos of the items from various places as well. Once an engineer, always an engineer I guess!

Time for an update. While my basement was being finished (Labor Day -Thanksgiving) I created a temporary work area in my den and actually continued to get some stuff done. Most of what I did was scratch build all of the interior items I wanted to add (mostly for the intercom and radio systems) along with other details. I'll probably have to stop for a while again, while I start to rebuild my work room in the basement so I can resume work there. Next big project will be the bomb bay as well as the radio operators station and the radio installation over the bomb bay.

That makes sense. It appears the bomb bay is pretty close to the main gear (give or take) and that would help to keep the CG in the middle to forward part of the A/C.

Hi Tom - I've been lurking in the shadows and just want to compliment you on your beautiful workmanship . Nice to see another post - hurry up and get the basement done so we can have more !

As an aside I have watched the Collings Foundation B 24 on several occasions and have come to the conclusion that it's center of gravity must be exactly over the main landing gear as I have never seen an an aircraft hobby horse so much while taxiing . Almost made me seasick while watching !

Cheers - Richard




That's interesting, and probably shows just how bombload dependent the thing was for balance...

That's also probably why the C-87 transport was so finicky (and was almost grounded after 2-3 accidents). The bomb racks set a regulated center of gravity, but a transport could have deadly variations if you were not careful...

Thanks so much for your kind words.

One of the problems of course with a tri-cycle gear model is to get it to sit on all 3 wheels as the CG without the weight of the real plane's equipment makes the model tail heavy. I put some weight in the bottom of the nose turret and inside the nose wheel itself, but what seems to have really helped is that since the engines all sit forward of the main gear, I stuffed a bunch of washers behind each firewall hoping the fact that it was quite a bit of weight would compensate for the fact that it was only slightly forward of the gears. I'm hopeful that it will be enough.

Having an aircraft with the CG right at just barely in front of the main gear would make landings and take offs pretty tricky for sure.

Time for an update. I managed to get the majority of the basement emptied out so the contractor can start the finishing project the day after Labor Day. But I waited until the last minute to close down my work room and attached is the next batch of photos on my progress. This will be the last update for some time, as I don't expect the contractor to finish until early-mid November, and after they're done I expect it'll be a while before I can get everything set up to get back to work. One thing I did have to do is re-work the ball turret. Turns out that the kit provided floor support sits way too high which means that when the turret is retracted inside, not enough is visible above the floor. And in order to allow the ball to sit higher in the support, I also had to make a larger diameter ring support which in turn meant I had to make the opening in the fuselage a bit larger. One of the problems you deal with when you scratch build I guess. Still lots of work to do, but I've done quite a bit of research on the communication gear so I'll be ready to tackle that and the bomb bay when I resume building

Hope you enjoy the photos.

Here's an update on my build. I've laid off the interior for a bit, but in what is probably a most unusual approach to building this kit, I've now completely finished off the wings and the tail section. This is probably going to be it for a while as we've decided to completely finish our basement and THAT means about 2 months on our part to go through everything and get the entire place emptied, and then another two months on the contractor's part to do everything. And probably some additional time to get up and back in operation.

For the nose gear, I liked the after market resin tire, but I preferred the kit wheel as it seemed more like the wheels I found in my reference photos,



so I cut off the kit tire, drilled out the resin wheel and combined them. Because the two halves of the kit wheel didn't fit up against each other, I used some washers as shims for proper spacing. And while it's not much, the added weight on the nose wheel will hopefully help out with balance later.






My next step will be to scratch build the scissors linkage on the oleo strut, since both the kit and my after market metal struts just have a molded blob. There isn't too much difference between the kit and after markets struts, so I'll use the after market one since it's metal and weighs slightly more than the plastic one from the kit.

Working on the landing gear. The first picture shows the kit tire and main oleo landing strut. I have the resin after market gear which is much better as well as tires which are done to show the weight of the aircraft. Neither the A/M struts nor the tires have the brake drums included in the kit strut, so I removed that, cleaned it up and installed it on the strut. The last photo shows a comparison of the kit version, to what I'll install.

Well, hockey season is JUST about over so I guess it's time to get back to work.

Switching over the the engines, I noticed that the exhaust manifolds are not long enough to reach the front cylinders by about 2mm, so I added some short extenders so they'll mate up better.





Next step is to try and figure out the best sequence for assembly and painting of the wings.

I'm now in the process of going back through this thread and replacing the old PB photos with the ones from IMGUR. May take a while!



I've gone back and (tried) to replace all of the photos in this thread with the ones from IMGUR, so please, let me know if any of you are not able to see them all now.

Thanks. I'm sure there was an easier way to do it, but I just grabbed my set of French Curves from my old drafting kit and used those to find what curves would fit.

I see the photos in the post two above this one but not the ones earlier. Cleared out the cache and all that good stuff. Imgur seems to be working for me (at the moment anyway!). Nice job of fitting in those fuselage formers by the way!
