Testors/McCoy .049 Pipe Bomb

Post  microflitedude on Mon Nov 14, 2011 8:39 pm

Not sure if this one get's the same name as the nylon case as it's the cast (iron?) one. If I recall correctly, pipe bombs are made with PVC. Shocked lol!

The cylinder is not burred as I originally thought. Compression is good. Runs for a couple seconds on primes, needle valve was closed when it broke off. Somebody might have a spare back plug/NV. I made a new reed from floppy material which passes the suck-and-blow test.

That looks like a high compression Cox head on the inside. Will a Cox fit it? What retains the reed?

This thing went through a serious beating. Very Happy

All the parts are a little bigger than an .049. The reed has no retainer - just slips under a lip on the back plug.

She runs!

Post  microflitedude on Tue Nov 15, 2011 2:25 pm

It shouldn't run, but it does. Smile

As described, the needle valve is broken inside the insert all the way screwed in - no fuel can get in through the nipple. I also removed the overweight broken spring starter.

I decided 2 second primed runs weren't satisfying enough, so here's what I came up with. Look anything like Soviet engineering? Popcorn It runs for about 15 seconds; I could do longer with the bigger syringe. Cranked it up, dropped the igniter and slowly pushed fuel in. It wasn't just put-puting, it was turning some good RPMS.
You might say I hand fed it. lol!

Watch out the rubber of the plunger breaks down over time.

Nice way to run a nearly-dead engine! Very Happy

You can always try to find a medallion-like spray bar, and use it as a replacement, so he'll be autonomous...

Yeah, I've got one of those, but installed in a control line plane... I never actually got the engine in my hands, but it's a screamer for sure! Very Happy

Yeah, it starts up nearly without priming, and I'm sure it peaks a 19k
