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.

Sweet! Love the faux radials.

wow, spectacular. well done! are you going to fly it?

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

How did you make the electronic connections. I want to build one, but I'm confused with the multimotor connections. Cannot fine a video.

Making the assumption that you have a modern radio with computer control, the left side of the plane has a left stick movement for more power and is generally tied to the rudder channel. This is mixed with throttle for power to both sides. If you have a pre computer radio, it gets a wee bit crazy adding mixers. I personally favored huge very authoritative rudder control since .049 stuff didn't have a throttle option.

These are fantastic! Definitely gonna get the cowlings printed tomorrow. Thanks for the files!
