more testing yesterday. I flew 110 miles to portland maine. 28 degrees outside and was able to fly with no jacket and gloves. Here is what i did
1 first thing is to call zack in parts at cubcrafters and order a window seal kit. It makes a big difference and the weatherstripping is superior to the stuff at lowes. I have a few more spots to seal yet but it really helps. This is probably the lowest hanging fruit
2 i got the following stuff off amazon

this is an 82mm x 82 mm vantech tornado computer cooling fan. Blows like hell, draws little amps, its 12 v
3 added a dc voltage controller, its a yeeco 12 v dc volt

4 added a cigarette lighter adapter with a switch and a fuse

5 put the controller in a plastic box

i had my friend john the tinknocker make me a custom piece of aluminum that fits on the floor to mount the fan. I have it taped with alum tape because i want to take the whole thing out quickly in the spring
john can be reached by text at 207-341-1063 and can make you one and ship as well. I dont know what he is going to charge $$ hes a honest and hardworking guy, even though he has a beard like zz top
it looks like this on the floor of the cub. It really not in the way of my size 13

i velcro the rotary controller to a lighter adapter i use, its easy to shut off with the switch, since the cub assc socket is live all the time

its my first attempt, i know it looks like polish farmers assembled it. It does blow out more heat without question.
If you run it in the hangar wide open, you can go up front to the intake and the suction is noticeable. I need to do some outside temps/ heat output temps on different days to compare. A big underlying issue is the single heat muff on one header pipe is not enough heat.
I am sending a setup to my pheasant king corp aviation facility in vt to try, i know he will give it a workout. The whole lashup weighs less than 2 lbs, and can be removed in 3 minutes. The parts from amazon were less than 50 bucks fire away, looking for ideas, so shoot bullets at my balloon. I would really like to see it come from cc done by guys who know how to do this stuff, but i understand its more weight and complexity, not what we all look for in lsa
