This was a buddy of mine from school.
He got into model airplanes, and decided to build a 1/2 scale cub.
He scaled up a set of 1/4 scale cub drawings 2X, and built it as-scaled, which made for a somewhat overweight plane.
The plane did fly well.
It had a chainsaw engine in it, perhaps 20 hp ?
Used a propeller made by a commercial airplane propeller manufacturer.
This guy was a free-lance type person, but he made things happen, and this plane was real, and did fly well.
I think a small person could have flown in this plane, but he never tried that due to the risk.
This plane had an 18 foot wingspan.
I think it had a motorcycle 12VDC battery to power the radio and servos, with probably a voltage converter.
Servers were the largest available, which were about the size of your fist, and two servos per control surface.
Overall weight was in the 200 lb range, as I recall.
Not really very big compared to todays large scale model airplanes, but for 1985, this was a sight to behold.
