Building the (scratch) R13 (part 9)

Hey, what’s this? My rocket has holes in it!Question is, though: Does it play? Sort of. Badly. But it plays. I neglected to try out the cheapo mouthpiece on a real clarinet before gluing it to the rocket, so I don’t know how much blame to assign to it. I thought the tone holes would…

Building the (scratch) R13 (part 8)

Here’s the nose cone. The finest clarinet mouthpiece money can buy anywhere, if by “anywhere” you mean “from Chinese eBay merchants” and by “money” you mean “five dollars”. The fit was just a little loose into the BT-55 tube inside the barrel; a couple wraps of tape snugged it up. Then I epoxied it in…

Building the (scratch) R13 (part 7)

The “keys” were cut from silver trim Monokote. What I ended up doing was pulling my “unrolled clarinet” photo into GraphicConverter, using the Edges effect on it, and flipping it horizontally before printing several copies. Then I used repositionable glue stick to adhere pieces of these pictures to the back of the Monokote, after which I…

Yes, we have no MLAS

I forgot to mention why the MLAS didn’t fly, again, on Saturday. I went to prep it ahead of time. I couldn’t get the nose cone off. Stuck. Wouldn’t budge. I’m hoping it’s the humidity and it’ll loosen up when it’s dryer. Taking it upstairs from the basement might help. At this point, though, I’m starting to…

Nymphail

I overlooked something when I checked the Nymph for damage. Do you see it? The rear stop for the motor pod — it’s gone! I have a theory of what happened. The Nymph has no thrust ring. The idea is you’re supposed to trim the model by adjusting the position of the motor, then friction…

au-198 flight

Gold dropping rapidly

In retrospect the snap decision to go with a streamer in the Au-198 should have been given more careful thought. With a C11 casing and an altimeter on board it’s fairly heavy, about 106 grams, and the fins do sweep back so are pretty much guaranteed to hit the ground first. Tim Van Milligan gives…

Syracuse Rocket Club Launch: Damage report, Mister Sulu

I’ve had worse launches. I think. But maybe none with as high a casualty count… July 2016 Syracuse Rocket Club launch. I was double booked in the afternoon so I got right down to the flights I felt I had to do, starting with my first entry in the ½A glider duration contest: the Uff Da,…

Building the Landis Nymph (part 5)

The last several pieces were glued on. Here’s a piece of launch lug (sloppily cut, as all my launch lug cuts tend to be) glued under the stab. There’s a piece of scrap balsa clamped to the top of the (inverted) fuselage to line it up. Some wax paper between the two is the reason…
