The most likely part to be damaged by water will be the piston, be sure to rest it on either end as it dries not on it's side or it could deform.
And double check it's fit the night before it's next launch and again on the day just before you launch.
Congrats on the certification, you definitely went above and beyond.

Phenolic is pretty waterproof.. I tried to soak some phenolic coupler out of a tube that had stuck.. a week in the dam and no change, had to smash it out.

Did anyone get a pic of the launches by chance? I forgot to film either of them :oops:

I'm happy to say now its certainly dried out the piston still functions normally and she will fly again! (at our next Westmar launch on an I, cause I'd like set a new PB and try hit that 5000' mark)

Quicksilver had it's fourth flight at QRS' July 9 launch on a new CTI I55-Mellow for a nice slow long burn to 4400'. Beautiful motor, and would be very capable in a lighter rocket.
Thanks to Matt for the video!

Nice one Digit.

I've not flown the Yellow Mellow yet, what sort of speed where you getting off the rod? Guessing this is why you went for the long one.

Only 8.1m/s off the rod, which gave it a below 'rule of thumb' thrust to weight ratio of 3.8:1, which is why; as you have noticed; I opted for the longer rail and to go a bank further out than I had to for that impulse motor. There was no wind either luckily or I would not have gone ahead with the launch.

Great photo! It was an awesome flight and pushed QT to the edge and survived just fine. Glorious weather too for Victoria ;-)

Fantastic pic, that rocket looks dwarfed by the trail of sparks behind it! Looks like perfect flying weather too.
