Estes used it in
Has it been used other places by other companies?
Not really being a Saturn V guy, I haven't paid much attention to BT-101 until now. Over the weekend, when discussing Estes 4-in tubing that is more like AT & LOC 4-in tubing, I got my head around the specs on BT-101. It is 0.021-in thick, same as BT-55, 60, 70, & 80. So it should weigh exactly 20 percent less than an Estes 3-in tube of the same length. Today, of course, I've been mulling over "big & beautiful," low & slow park flyers made from BT-101 that would fly well on E12s from Hobby Lobby, or maybe D12s.
Just wondering if anyone is using it for LPR/MPR sport flyers. Old standards, something as simple as an Alpha or Goblin, could be fun. A little bit of sound and fury from the motor, send them up a little bit, and bring them down very gently on a big chute.
I reckon the challenge is likely going to be nose cones that match up to the thinner wall and don't add so much weight then end up requiring more power, beginning an upward spiral of weight and power until you might as well double the body tube thickness and you've moved away from the whole idea entirely.
