Anybody wants to come use my bin, you're more than welcome It seems like it would work, but there are a few problems that I see. First, if the plane doesn't release, or something else goes wrong, the plane is pointing at a very large steel object(and it's surrounded by smaller bins and the grain dryer). Second, and more importantly, it's not close enough to my "thermal" field. On a good thermal day, I might be able to fly my way there, but for an average day, I'm not good enough with thermals to make it. Might be worth exparamenting with though.

Your plane may be pulled toward the steel bin, but it will go slack by the time you get within 100 or 200 feet, or however much extra line length you have. You need at least 100 feet if you don't want to climb the stairs to retreive the chute. If the area below is obstructed, you may have a point, since when you're stuck on a high start the usual tactic is to circle the stake until you land.

In my experience, thermals aren't attached to stuff on the ground, and they move around, though they often break free when they hit an obstruction. Such as a 100 foot grain bin. So if you have a place to land..

I don't know what shape your bin is, but if it's got a wide enough face it might be great slope soaring when the wind is right.

Good point about the distance, crashing into anything wouldn't really be an issue. The bin is big and round, but stands at the end of a row of smaller ones. A more experienced flyer could probably slope with the right wind, but not me. I've tried a few times with no success and I can tell the cables and scafolding around the grain dryer are just itching to grab a plane...

Probably depends on how far apart the bins are, how high they are, and if there are obstructions upwind of comparable height. An obstruction can be pretty far upwind and still create a problem.

Holy Cow, my home made high start actually works I've got about 40' of 1/4" silicone tubing, and about 100' of 30# fishing line. Not ideal, but I've got less than $20 in it. I don't have any spare BECs, so I just plugged an ESC in to power the servos. I'm currently flying from a harvested soybean field, and my first "landing" caught some mowed over soy stalks and ripped a 6"x8" hole in the bottom of one of the wings. Every flight after that went pretty well. It was getting dark so no thermals to be caught, but even with my short high start(maybe it's just a medium start?) on a good day I can get high enough for some soaring

Congratulations on your home made hi-start. My first hi-start was home made too. Worked grerat!

Why yes, yes I did I also scored a vintage Tamiya Grasshopper buggy for $20. The glider wasn't even really out on display, I just happen to see a stack of wings on the corner of a booth and investigated.
