Title: Dave Slagles Nat's engine flying again
Post by: Ara Dedekian on May 15, 2020, 08:08:12 AM: I've been slowly restoring the spark ignition engines that were given to me by Dave Slagle. They came in a box of bits and pieces that he'd kept since his Walker Cup days. The Super Cyclone below was somewhat intact and according to the best of Dave's recollections, was used in his 1946,47 or 48 wins, but couldn't remember which year or the plane it was mounted in. I got help in sorting and assembling the correct parts from the Ignition Engine section over on the RC Groups forum. One of the Super Cyclones in the batch was apparently a prototype with a split case that none of the collectors had seen before. Dave used to get prototypes from Atwood, Anderson, etc. to try out.

It's been flown once so far, straight and level, and worked like a brand new engine. The Taurus has a uniflow 3-1/2oz tank which gave an 8 minute 45 sec run. The ignition system is Floyd's transistorized circuit with a 3.7 volt LiPo. We were grounded the day the picture was taken by 20 mph winds so I haven't tried any basic maneuvers yet.

Kind of exciting; for me anyway,

Type at you later,

You did a really nice job on it and I am glad to see someone else getting into ignition. There seems to be only a handful of us left.

I'm just 86. I figure another 20 good years to finish everything I have planned.

Floyd is there no end to the cool planes you've built.

Post by: FLOYD CARTER on May 17, 2020, 01:15:58 PM: Ara. Just reminded me. I probably watched your "Slagle" Super Cyke run. Dave and his parents were frequent visitors to our flying field in South Gate, CA (L.A. County).
About 1948 (probably), the Slagle clan would show up, and Davie flew his stunter. Don't remember which plane, but it was a Super Cyke for sure. In 1948 I was 14, and struggling to learn some basic C/L maneuvers. I think Slagle was a bit younger.
