Run of my Testors fly 'em' P40

Hey, bandit.
Thanks for the entertaining briefing on the Fly'em Testors. That was cool. Nobody would get dizzy on that thimble sized tank. But it sounded really healthy.

Sounds like an airplane made for me Bandit. Six times around the circle and it runs out of gas. Only problem is I run out of gas after only five.

Wondering how those Fly'em engines "key into" the fuse. If they're retained by the slot in the case only.. there's been some experimental mods done to the backplates.. that could possibly allow you to run an external tank of slightly larger capacity.

Maybe by using this; an item that Bernie may still have in stock. Not sure if it fits your engine though.



or.. if you had a donor-backplate of the same type.. you could trim-off the integral tank like Mark (batjac) did here.. and affix a fuel-line. (it's no wonder the engine doesn't run very long..)  




Here's a photo of mine; after some surgery with a razor-saw.



It's interesting that there's a "barb" already there.. just waiting for a line to be attached. I've never had a Testors ARF.. so I don't know what's involved in taking one apart.. but if it's not too hard.. and won't pose a threat to any of the retaining-system.. (screw-bosses etc.) there might be enough room to install a short (5-7cc) wedge.. and run a vent-extension right out the top; where the original fill-point is.

There should be a hole in the belly, where you can route an overflow hose down through. You might be able to make the mod without surgery to the model.

Some different packaging..

This shows a boxed-example with the "zip-starter" that you spoke of in the vid.. (curious as to what the round object is, in the lower R/H corner.. looks like a vinyl record. If so; was it possibly an operating/flight tutorial?)



and here's another packaging design.. that probably could be "peg-boarded" at the retailer.



Mark Boesen could tell you more.. I'm sure.

That is exactly what the record is it is acculy more of a Mylar type of record meaning that it is flexible like a thin piece of lexan.
when I got my Spitfire which had the zip starter it came with one also.

Theres not much room in the nose for a tank. doesn't mean that you can't strap one to the side though. as far as how it "Keys" into the fuselage, it has a tang that engages the tab located on the side of the crankcase. (Bandit)

Hey TD That's a pretty good runner there and informing video , that plane is small i would think even with a not so powerful engine it would get around the circle pretty fast ! Thanks and good to hear from you !! Eric

The late Bill Netzeband did a lot of the design work for the 'Fly 'em series planes, here's a reply to an email i sent him years ago:

What was up with the fly'em engine with no threads on the needle, when was that made?

The no-thread "fuel control" was an attempt to fit an engine with a single turn valve, which had logical sequence positions to provide, 1- Wide open to prime intake during tank filling; 2- RICH mix to start cold: and a "RUN" range to lean out the mixture to "speed up" the engine. There was a position to shut off fuel, in order to crank off a "flood", or to quickly "kill the engine. We got suckered by making prototype parts that performed exactly as designed. During the first production run, it became clear that we couldn't MOLD the plastic valve stem and the mating slot in the plastic tank consistently enough to cover the minute range of metering area to do the same job as the prototype machined parts! Unfortunately, we were committed to ship quite a few defective products, before going back to the "venerable" needle valve system. There never seems to be enough lead time to complete and test a perfect product design, but plenty of time to "do-over". "

Best Regards,

Ok, This is getting interesting. Time to go check my Fly'ems.

Mark, I don't have one of the engines with the metering valve, but have always wondered how hard it would be to fabricate your own metering rod.

Roddie, I have a P-40 that's still new in box. From time to time I consider opening the box and playing the record so I can make an .mp3 of it, but I just hate to open up a never opened box.

Well Mark.. I don't blame you for not wanting to open a sealed box. It would be very cool though, to digitally-record that disc. I doubt that anyone's attempted to do that. I do have the means.. but not a disc. I'm sure that they're quite rare.
