Well, okay.  Maybe just the improbable

After we’ve been talking about refitting fine needles the past couple of days, I came across an unfinished pipe bomb conversion, and thought “why not?”  So I pressed out the Testors NVA from the modified pipe bomb backplate and pressed in a spare 128 TPI Cox NVA I had in a bin.  I swapped this backplate out for the one I had in my Pipe Bomb Special engine: https://www.coxengineforum.com/t9945-im-so-weak#126033

The engine starts pretty easily and runs at about 14,700 RPM.  I’ve run this engine on a tank, a balloon, and now bladder.  14.7K is all this engine will do on a Cox 5x3 rubber ducky.  But that’s plenty for just simple sport flying on this plane that only weighs 5 ½ ounces.
