Went to a nice organized launch yesterday. Took two possible Level 1 cert rockets with me.
Figured if I had the opportunity to find a 29mm H motor for one of them I'd give the old cert a try.
Well after flying half a dozen flights an H238T was offerred, so I decided to jump on the opportunity.
Had already launched the 3" BSD Horizon on a G35 for a beautiful flight so decided to go with the 3" BSD Sprint for the cert flight.
Was a little windy but the motor had plenty of punch off the pad so wasn't too worried about that, and we had plenty of room for recovery.
Loaded up the motor, and double checked everything, started getting worried when people commented too much on how nice the rocket looked.... LOL
Got it on the pad, and then had a long wait for a hybrid motor to get ready and flown then I was up.
5, 4, 3, 2, 1,...WOOSHHHPOP.....
Had a delay blow by and the ejection charge fired in mid burn.. a very quick flight to say the least.
So the "beautiful" rocket came down in three pieces. Booster section core sampled, chute floated away with the shock cord, and the payload came down undamaged.
Will need a tube coupler, section of body tube and some new decals and it will be repairable.
The tube is crushed/kinked for about the top four inches, and then again above the fins for about a 5" section.
There was some discussion about where the delay spacer went, fore or aft of the delay grain, we placed it fore and i think we had it turned around backwards, not sure if that would cause the blow by or not.
Disappointing at first but kinda funny now, I did however learn a bit and will have some fun repairing, will be my first major repair job so it's good to learn it.
Only draw back is that my brother will be attempting next weekend so I won't get to beat him to the Level 1 cert.
Oh well, there's always Level 2 to beat him to.
Here's the sprint before the fatal flight.. heh heh
