But I gamely sanded off the orange peel and resprayed.
While assembling the recovery system, I discovered that a slightly sanded BT-55 is a slip fit inside whatever size the MPC body tube is, so I added a Semroc BT-55 baffle and kevlar to a short section of BT-55 and badda-bing, no more wadding. Kind of over-kill for a rescue but . . . .
We're shooting for a launch tomorrow, wind permitting. It'll be ready.

It's the Quest (originally MPC, then AVI) T35 (35 mm O.D.) tubing. That is good to know about the sanded BT-55 sleeve-fitting inside the T35. While Quest makes stage couplers/tubing couplers--and thick card stock closure discs--for T35 that could be made into ejection baffles (by punching holes in the closure discs), using the ready-to-assemble Semroc BT-55 baffles is much easier and quicker. |
