Please tell me that it's not meant to be man-carrying?I asked somewhere online about the OP's plane (I thought it was here but maybe not) around 1.5 Oshkoshes ago and got an answer pretty quickly. From what I remember it's a one-off, built to be about 3/4 the size of a popular 50's-60's home built biplane (Smith Miniplane? EAA Biplane?) and powered by some APU radial. What's not easily apparent from the pics is just how tiny it is. If you parked it next to a Pitts S-1 the size difference would be about the same as that Pitts next to a Stearman.
IMO it is, too - post #10 below:Couuld be a Lawrance radial engine, 37HP, 5 cyl., was used as the APU generator on the B-29.
