I'll list interesting (little) projects here.  Note that 13 and 18 mm will be the BIGGEST motors these rockets can hold.

Talon on an 18mm motor
 
09/20/09 - Flew the Talon on a D24-10 motor, and was disappointed to find the rocket was unstable.  Didn't break anything (after tumbling around the sky), but it was sad.  Re-balance, and check Rocksim again.  I was sure I had the CP/CG relation right...
 
10/03/09 - Flew the Talon again - this time after adding 3/4 oz shot to the nose, and moving the CG forward a full caliber.  Used a D24-10 again, (shortened by about 2 seconds), but using an old delay element (add about 3 seconds...).  Tore off the pad, and kind of circled/wandered around about 700 feet up.  Ejected very late, but deployed successfully.  Later, broke a fin in an accident.  Nuts!
 
10/17/09 - October Skies - Flew the Talon on a D13-7, for a high, awesome flight.

090920 - First flight of Talon at XPRS on D24-10 - Unstable - Pat W pic

 

Classic Estes Cobra
 
09/20/09 - Flew the Cobra on 3 x B6-4's, to a high, straight, flight.  Ejected at apogee, and floated down.  Broke a fin in the heavy wind.  Nuts!

 

Baka - 18mm, flying, pop-pod rocket.
 
05/31/08 - Flew on a B6-2, and the ejection was too late - plunged into the ground.  No damage, though.
 
06/14/08 - Flew the Baka on a B4-2.  Didn't get off the rod, until ejection!
Flew it again on a C6-3.  Weather-cocked heavily and hit before ejection.  Cartwheel and heavy damage.  Dang!!!

Tinee - 13mm Edmonds Canard glider
 
05/17/08 - Dairy Aire - Stuck on rod, and blew off nose cone.  Couldn't find it!  Luckily, I had another...
 
05/31/08 - Flew off the top 1/2 of a rod at Newark launch.  Nice flight and glide!
 
06/28/08 - Newark - Flew Tinee on an A3-4.  Fsss-Bang!  Motor blew up just off the pad, and the glider glided off into the distance.  Found the pieces - little damage!  I've never blown up a 13mm before...
 
09/21/08 - XPRS - Sunday - Tinee on an A3-4.  Delay too long, and it arc'ed over badly.
 
12/20/08 - LUNAR at Ames - Flew on an A10-3. Kinda high, but it didn't eject the motor - came in kinda hot.  No damage.

01/17/09 - LUNAR at Ames, again. - Flew on another A10-3. Same thing happened - kinda high flight, but no ejection.  As before, came in kinda hot, but no damage.

08/01/09 - Aeronaut - Flew Melissa's Tinee on an A10-3 - Blew the nozzle!. 
 
08/01/09 - Flew Tinee again on another A10-3.   Arched over backwards, and ejected just before landing.  Gotta figure this out...
 
09/17/09 - XPRS - Flew Tinee on an A10-3.  A (somewhat) straight boost, for a change, and transition at the top, leading to a straight glide away from me.  Nice to see this fly well, for a change.  No wind helps....
 
10/3/09 - Newark - Flew the Tinee on an A10-3, which transitioned into a great, straight glide.  Went way out into a field, and Steve P retrieved it.  Gotta put some turn in this thing!
