Webra 1.7cc Glow Engine

I bought a new in Box Webra 1.7cc. [.10 ci] This is first one like it I have run across. Little Jewel for certain. Webra made fine line of engines. This has four both head and steel finned. awesome compression. Box and papers in very good shape. Older Gent retired from models sold this engine. I was going to put it in Ringmaster JR, but use something used instead.
I fly mostly C/P helis/ foamie 3 D planks/ and last summer got into Sailplanes. Flew controline many years but expanded my flying interests.
