Okay, next off the wall question. Does anyone know anything about the subject engine? While rummaging thru the stash, I came across a box of engines. They came to me from a now-deceased friend maybe 10 years or more in the past. Most of the engines are small diesels, modern and repros of older designs. I found two pristine boxes and engines labeled "MP Jet .061 Ball Bearing". Looking at them, I'm pretty sure they have never been run. I'm curious about what has fallen into my lap. So any knowledge, info, opinion, hearsay...?
Given that they are European design and manufacture, my only guess is that they probably work best on little or no nitro, but who knows... If they have power, then they might be a candidate for some of these more modern 1/2A stunt designs.
TIA,
