That's funny, if you time most of my videos, given the flight weight of 10.5-13 ounces, they have about a proportional flight time, lighter ones have a 1.5-2 minute dead air flight time and the heavier ones go down to about a minute. The YF-12 is an ounce lighter than the kit due to he way I was able to build it, since it wasn't a kit I didn't need a coupler and with the reduced chines the CG is about 3/4" further back so less nose weight, you get about 10 seconds more glide. Sometimes with heavy wind get more in the heavier gliders, somemtimes less due to having to line up with a runway if I'm at my club, when I land in a field I don't have to sacrifice flight time to land in a particular direction.

Glide time looked fairly impressive on the E6 compared to some of your other gliders.
Would be really neat if you could air-start a second motor to extend the flight time.
