Depron "Pan Am" Boeing 747

Ive finally made enough progress on this plane to post some pics and info. Ive completed the fuse and tail section and still working on the wings. It will have 4 EDF-40s. So far it weighs 7 ounces, I expect the final weight to be around 20 Oz. I am also going to fix in place the leading edge and trailing edge flaps to give some more wing area and greater lift.

If anyone is interested in the details of the build I can post more info.

On the finish it was the testors Model Masters, I lightly sanded the seams with 400 grit, then followed that by a polishing type paper I found it at a craft store, its a on plastic backing seems about 800 grit or more I"m guessing, it never really said, the polishing paper really put a nice smooth finish back on the depron. it seems with my experiments once the plastic skin of depron is damaged it is super rough, even when sanded with 400 grit it roughs up quite a bit.
Anyway, after sanding it smooth I used the primer, put one one coat, then I wet sanded it with the 400 and then again the polishing paper. After that it was ready for the White, it glossed up real nice and for the silver I used their Chrome, nice and shiny, looks like polished Aluminum in person, pics don't do it justice.

I experimented a lot on spare 1mm depron. (used for the skin) before I did the actual model.

It was made by blowing up a 1/100th scale cardboard model made in germany. I was Inspired by other threads one here which had followed simililar methods. It went together very nice, OF course, Ihad to make some mods since it was going to be a flying model, such as wing support, internal support for the vertical and the Horizontal stab, elevator controls, Nosewheel steering and stuff like that. The structure was very strong, it is built in modules, which I then Epoxied together. The fit and finish was outstanding using the pieces exactly as the model used. I did however use a foam block for the very last tail section, about the last 1 inch.

I took the cardboard version to Kinkos and blew it up 150%, this made my overall length around 39 inches. I found that using an ordinary glue stick to hold th paper onto the depron while your cutting worked great, it sticks with slightly more than a post it does and it doesnt damage the depron. Heres a pic of the assembly diagram and some of the parts blown up, original on the left, blown up on the right.

Ill post a link to the model I used. As far as the decals I found a good source for those, he sells decals for classic airliners for a lot of different airliners, he has a 1/100th scale Pan Am set for the 747 so I also had those blown up 150% at Kinkos and printed on a clear Laminate sticker type paper. He stated he could blow them up as well and print them on white back ground instead of the Lt. blue decal paper. His email is : markbob@ameritech.net if your interested.

The edf 40s are about $15 each, still shopping for the best/lightest battery pack (lipo)

Depron, I bought a lot, probably enoughh to build 5 of these, and I spent a total of about $75-80.

I used 6 mm white depron for the internal bulkheads. could have probably gotten away with 3mm.

For the wing, I'm going to modify the wing from the Cox XB-29 Airlifter, I like the airfoil design and I am going to sheet the top of it with 1mm depron for added strength and it looks better. You can buy these wings from COX for about $10. I like the way mine flies and like I said I will be fixing in place the LE flaps and the TE flaps in the takeoff position.
