Thanks, guys - I'd seen reference to that premature ejection problem in scanning old posts - in fact,, a reference to carbon fiber shielding is some of those posts prompted my question about the encap...

Thanks, Warren - I'll proceed with the plan as drafted.

Rookie question - in the planning stages of a new project. PML has an 'Intellicone' - plastic nose cone with a built-in payload bay. I'm looking at a 4-inch cone with a 54-mm payload for a dog collar ...

And taking it out this weekend for a real test drive (wifey along, so she'll definitely point out all the flaws). 🙄

Thanks, Tim... wanted an excuse to buy some 54mm hardware and start thinking about an L2 cert project anyway,,, so I'll burn this one later this summer (if we're not fire constrained all year) and may...

Got a PML Miranda (2.27 kg with motor loaded) that I launched in early May on a Cesaroni I212 Smoky Sam - looked straight and true. Thrust curve on the I212 is pretty square,,, very little difference ...

I won't be able to make it that early - but will try to be there around 3..

@MikeS... Got Thursday and Friday off, so thought I'd come out with my little travel trailer (and grandson) and help with set up on Thursday afternoon and Friday morning with set up. What time do you ...
