I bought my grandkids an Estes Flash. We launched it 4 times over the Thanksgiving holidays. You should have seen all of the jumping, whooping, and hollering I could barely hear my grandkids over all of my noise Kidding, a little. On the last launch the guidance had a glitch, that would be me, and the rocket ended up coming down in the top of Pecan tree. We didn't figure out a way to get it down. Fast forward to the week before Christmas and I noticed it wasn't sneering at me from the top of the tree. Sure enough, it was intact, a little (lot) damp and it looked repairable. I took the plastic bits off carefully, straightened up the chute and cords, and inspected the tube. The tube was going to have to be replaced. A month exposed to the elements had left a soggy white main body tube. The pretty colored wrap was gone. I measured the tube and started looking for a replacement. Standard BT series tubes are too big. I found some ST-10 tubes on ERockets. I bought one ST-10 tube and one ST-11 tube. The ST-11 tube was 1" long Didn't matter. The ST-10 tube is too small and the ST-11 is too big.
Does Estes use oddball rocket tube diameters?
