Tubby B17 Build

I have just finished my Tubby B-17 build. I added a few 3D printed accessories such as dummy engines, top and bottom turrets, cowls and cowl flaps.

Yes, flew it before I painted it and put the faux engines in it. It took a lot of tweaking the rudder channel for proper differential thrust control. It flew great but took some ground handling practice. The second flight I dropped the Tubby Bomb to everyone's surprise. A lot of FUN.

I'm sure everyone has a way of doing this but this is my solution. I wanted to keep the small numbers on the tail properly aliened. I cut out the just slightly outside the numbers on the vinyl graphics page. Then I put it face down on the sticky side of a sheet of Glad Press n' Seal. Then pealed the backing off the numbers keeping them on the Press n' Seal with the tip of my exacto (a tooth pick will work too). Then place the Press n' Seal with the numbers on the tail, rub them onto the tail then slowly peal off the Press n' Seal. Perfectly aliened numbers!

That's a lot cheaper than using "official" backing! Great idea!

Here are the STL 3D printable files. I printed the faux engine mounts from ASA (or PETG) because it is very close to the motor housing.
Also the alignment pin on the faux engine mount is placed on the bottom, The Wright Cyclone was installed in the B17 with the odd numbered cylinder at the top position unlike many of the fighter engine installations. I printed these all in PLA Plus with 2 shells and 5 percent infill to keep them light. The gun barrels I printed from PTEG to be less brittle.

Love the build, printing the STLs for my build now. Thank you for them.

Quick question, I assume you are using the Budget B motors from Flitetest, correct? What propellors are you using for the 3 blade props? Where did you get them?

Thanks
