So, both of you have been peeking in the windows of my workshop area, huh?

Carl:
anything over 4 inches would be more than usable, but in all honesty I don't really know. The original concept was to be able to use this wide variety of engines in it and just put a spacer in based on the length of the engine. The MMT is at least 7 inches long (my 6 inch ruler gets lost in there). I have a Semroc order ready for Payday. I was just hoping someone would chime in with that part number. Really whatever size you have on hand works, and if it is small, I'll just get two. One other thing Carl or anyone else, is the Semroc quad motor mount in the RockSim (that's getting ordered too)? I have another idea I am working on and want to hash out the idea before I build it. Weather permitting, launch is Sunday, and we will be trying to video the thing. I currently have 8 in my fleet (Mimi, Guardian2, and NuB-1st are on first flight). Hope to have a good launch report to share. Thanks to you guys for all of your help. I didn't take too many closeups since I had some paint bleeds under the tape that I was using. They are small but I know they are there. Next step will be picking an RMS and loads for it. Suggestions are always appreciated. |

If you can get a closer measurement, we can cut it the correct length.

Carl:
I think I will just order an 8" tube and cut it here. I tried to measure it but I can't be as precise as I would like. If I take the 8 slip it in and mark where it exits, then I will know for sure. From there I will subtract the length of the longest available engine and put a block in at that depth. From there the tube gets cut into spacers for different length engines. In theory this should be fine (though I am not the original theorist, I think it should fly). JTHRO: Feel free to farm out any of those kits you want built, I have a little bit more time off my feet and my hands gotta keep doing stuff. I can get around OK if I need to go to the store and get supplies, but I am doing a lot of sitting (reclining) as my ankle heals. Did get a pretty cool desk for free and now have a good reason to set it up. Someone gave me a Drafting Desk. Pretty high end one too. Never been assembled. 1 piece of glass to cover the top (to keep the x-acto from tearing it up). New rocket platform. Then my only problem will be displaying them and carting them to the field without getting them bunged up. |

Flight Report: Nu-B1ST
Temp: 50-55F Wind: NNW 5-15 Skies: Mostly Cloudy Launched into the wind at just over 10 from TDC. Engine used was the Estes D12-5 friction mounted Flight was straight and true. Chute deployement just after apogee, some small damage to the top tube (dent). Since we had more than a few rockets to fly (and send up yet another toy using the AstroSat LSX) we opted hold off a second launch while the winds were tolerable. Launched the Mimi with a D12 but did not get the cool whistling that we were looking forward too. Then the troubles. Gnome went up on 1/2A engine and we lost it in the sky. Another sacrifice to the Rocket Gods. Fireflash went up and the Chute incinerated (not enough or poorly packed wadding). There is a lot of clay in that BT5 top tube so it came down like a spear. The B6 that we used got so hot that the plastic fin assembly melted. SkyWriter's shock cord mount gave way so the nose cone drifted down range but the body came straight down. We only used an A engine so it didn't have too far to fall. However the eraser look body tube looks like it was stepped on. It also is beyond repair. Guardian2 on C6 had a wonderful flight and recovery without incident. Code Red had a misfire. We never got around to launching it. AstroSat LSX, what a deal. Got this at Bellville hobby on clearance. The big body tube and room for two "satellites" leave me plenty of room to stuff in one of HannahMonster's little toys on an 8" chute. She was so excited she was dancing around all over the place. My custom Viking got most of it's fins knocked off as well as I found a good crack in the wing of the Nu-B1ST and a suspicious footprint. Otherwise, transport launch and recovery did not break the wing. The crack is not all the way thru, so I am debating what to do. I may break it off, glue it, then do both wings in MonoKote. Oh, we also found the remains of HannahMonster's Swift 220. Looks like it was trampled by a herd of wild buffalo. Even the tiny little nosecone was split in 3 places. Well, that was my Sunday, how was yours? Last edited by bikegod : 03-26-2006 at 08:12 PM. |
