Terrible weekend weather appears to strike again! Bummer .
What's everyone working on? I've got a PML Miranda in pieces on the dining room table. Scheduled for completion by 2025 .
Yeah the April weekends this year have been bad.
You ain't kidding. We've timed races the last two weekends (outside by 5 am)...about blown away and half frozen. Mercifully we don't have one scheduled this weekend.
Oh. Neither rain nor heat (or sleet ?)...
The consolation is we're warmer than Boston... or Minneapolis... or...
BTW are you going to carry the Q-Jets ?
Pyro, I’ll try to beat you and target 2024! Lol
I did pick up a 54/1709 case..... what loads should I try out?
The K185 is my favorite reload in that case. The perfect motor for a minimum diameter 54mm, seems to go forever. On the other hand, if you want to test your building skills, the K1103 also in a MD will do it, just a beast of a motor. About 25% more impulse than the K185 in 1/4th the burn time. The K550 is a good compromise between them, classic White Lightning burn....I did pick up a 54/1709 case..... what loads should I try out?
For the longest time my favorite motor for smaller rockets was the K550W until discovering the new K2050ST beast for the 54/1706 casing, you have to give it a try! The K185 is another favorite for that eternal burn time.
When I first started I bought a lot of PML kits that used pistons. One issue with the PML kits is that the plastic quantum tube contracts a lot in cold temps which can cause the piston to bind. Another is is that if you build it according to the instructions the loop for the d-ring is not very strong - you need to have real loop, not one formed by epoxying the tubular nylon to the piston bulkhead. I also had a PML metal d-ring fail on me during a hard deployment. (Admittedly is was on my Sudden Rush which I built over 15 years ago so it had a lot of flights on it, fortunately the fincan survived.) You also have to wash out the inside of the body tube to clean out all the bp residue or the piston could bind on that.So this is the first kit that I've built that was designed with a piston. I seem to recall that a lot of people omitted them for whatever reason but maybe I'm mistaking.
What would you all do? Piston or no piston? I do like the thought of not having to deal with chute protector and/or wadding.

They really do offer some benefits - I never had a chute fail to deploy with a piston and packing the chute was fast and easy. But they have their caveats. It's worth trying at least just for the experience.
Good luck,

Any high power go up on Saturday?
Sam, is Gunter HP happening next weekend or the following? The website is not updated and I would like to attend. Thanks!
