Swap meet Saturday

Ron, didn't you FUBAR one of the Woolard .40's you were flying? Would the .40 you show make for donor parts? The .074 is a neat engine lending as much power as a modern .10. Problem with the .074 is finding props that suit it. It's one of those engines that fall in between prop sizes. I did find for control line use that Master Airscrew makes a 6.3 x 3. The Cox grey TD .09 prop the 7 x 3.5 works but it puts a lot of load on it. It's one that likes to run all out. But, this is also an engine that's very light for it's power. One of these would be very nice on a laser cut Ring JR or small .15 sized planes. I had one on a 1/2A pathfinder but taming it down was problematic. I was flying on 58' lines and tweaking props to flatten out the pitch as this thing had me flying combat and not stunt. For whatever reason, they also chose to use a fairly substantial prop screw which requires you to really open up the hole. This makes the prop specific to this engine only now. Ken
