1/72 B-29 Thumper decals, & spinning props
Posted by 7474 on Thursday, December 11, 2003 12:30 PM
Hi all:
yesterday at work, I meet the navigator who was on thumper. for those of you who don't know what thumper was, it was the first B-29 to complete it's tour of duty (35 missions). It's like the memphis belle of the pacific.
Any ways, not the fact that he and his crew are a legend in way, the B-29 was also in the same group and squadron that my uncle's B-29 was in. the 497th, 870th Bomb squadron. His B-29 was WereWolf, but was shot down jan 27, 1945 by a Kawasaki Ki-61 "Tony" hein. I don't recall what the japanese fighter pilot's name was.
Any ways I need help with some thing. He asked me to build a model of his B-29. I told him that I could, and would try to get the props to spin, and the lights to turn on.
Does any body have any wiring diagrams and instructions on how to connect 4 pager motors to a switch? What about the power source?
Lastly, does any body have any 1/72 scale decals for Thumper? Any info would be greatly appreciated.
P.S. It was great to see the look on this gentlemans face when I told him that I did lots of drawings of his aircraft, and admired him from a very early age.

As far as a diagram for the motors, just keep them all in parallel. Say each motor has 2 terminals we'll call 1 and 2, the battery has 2 terminals A and B and the switch has 2 terminals we'll call x and y.

Take a wire directly from battery terminal A to switch terminal x. Then from switch terminal y take a wire to terminal 1 on each of the motors. Then from terminal 2 of the motor take a wire back to B terminal on the battery. With the type of motors youll be using if the motor spins the wrong way you can reverse the polarity of the battery by flipping it over or interchanging terminal A and B.
Fighter pilots make movies. Bomber pilots make history.

I did the 1/48 B-26 "Flak Bait" on a base dipicting it fixing to lauch for a mission. Had spinning props and working landing lights. Wired it through two figures in the bomb bay. Looked like they were doing last minute checks. I used 4 C cell batteries in base and an electronic "dip" switch (4) so I could run one engine, or two, and the landing lights. The figures connected to the model by sub minature jacks so the plane could be removed from the base. I started wiring a 1/48 B-29 and put the "dip" switch in one wheel well so I could "program" what engines I wanted to run. Never got it together yet. I think I will look into making some kind of "receptical" to use the Mini Mag replacement bulbs for landing and interior lights in future models. I had gotten the "dip" switches and sub minature jacks at Radio Shack.
