Interesting - browsing through Estes' latest offerings and finding the Mega Mosquito.
Back in the late 70s the club I belonged to (Skywatchers/ROMAR) in Colorado Springs ran a contest with an unofficial 'fun' event called 'Kit Scale'. This consisted of taking an existing manufacturer's kit and making a larger scale version of it. The model had to be turned in for judging alongside the original size kit. My entry was a BT60 sized Estes Mosquito built of parts from a Big Bertha kit, and fitted with a D engine mount and parachute.
I called it the "Skeeter Eater"
It turned in a spectacular flight on a D12-7 !!
