Grizz

Love the radial engine.

Has anyone ever made a model radial that is double or triple row?

I do not think so, but Saito was offering a 9 cylinder several years ago for about $5000. They were, iirc, built to order.

I had a brief run with ducted fan jets in the 72 inch class about that time, and boy did those radials sound sweet. It's been close to twenty years now, and we still run up to an old airport every summer and watch them run. The new planes can be set to automatically make up to a 90-degree turn on autopilot. At 240+mph the real scale jet motors can get them to a different time zone very fast.

I quit when I came within 30 seconds of losing about six grand worth of plane. It would run close to 200mph, and we used to run them on the Interstate in relays. Cars with the same channel radios staggered about 5 miles apart. We lost battery, and luckily it was landed in the backseat of a buddy's '67 GTX ragtop with very minimal damage.

great clip guys, thanks.

Flew RC for a very short time. Much rather watch others fly and crash. Love the jets and radial engines.
