One of the curses of this hobby is seeing things and thinking "I could put a motor in that!"
That's what happened today when I was in the Dollar Store while my wife was looking for Easter goodies for our granddaughter. I found this and my wife said, "She's not old enough for that!" I responded, "It's not for her - it's for me."
Here it is:
It's called the H2O Blaster. Essentially a transparent tube with a plunger to draw in water then shoot it.
Here it is with the plunger drawn out:
The diameter is about 1-1/8 inches. Big enough for an 18mm motor. The yellow plunger rod is 16mm, so I'll have to ream out the "nozzle" a bit - unless I go with 13mm. As it is now, it weighs 3.5 oz.
Because the "nose cone" and rear ring are pretty strongly glued on - I'm thinking rear deployment of the parachute or streamer. I could cut the internal tube off a few inches behind the O rings on the plunger and attach the recover system to that (I'll have to work out the specifics).
The body itself seems to be fairly substantial and still mildly flexible. I think it will hold up well to a LPR launch and recovery.
Because of the rear recovery, I can't use thru-the-wall fins - but I was thinking of Lexan and epoxy.
By the way, it comes in three different colors - in case anyone else wants to try one.
First step is to soak off that paper sticker.
