I built a boat. Used an .074. Lots of fun.
The new RC planes are incredible, jet engines , retractable gear.
Remember chasing a friends RC for miles after he lost radio contact.
The thing had 1 channel, rudder. The rudder fluttered back and forth. Plane turned depending what position you stopped the rudder.
Let’s see. Hmm either left(x) or right(0).
By jolly, it was digital.!
I had the small Dumas Swamp Buggy with a Cox .049 and a 2-channel radio. It may not have had the speed of the hydroplanes and the big tuned-pipe engines, but it would run all day long. Later, I put an O.S. .10FSB on the boat. Boy, that woke it up.
