LAUNCH! Soccer Field September 10, 2011

Today was the first cool morning in a long time.
High scattered clouds and no wind!



First in the air was the Hot Rod Rockets BELL BOTTOM with an Estes A3-4t. Straight boost and no drift under the metalized streamer. Estimated altitude was 425 feet.






The Truax carded SCAMP was launched with a 13mm A10-3t engine friction fitted in a 18mm engine casing. Apogee was at 250 feet with 12" garbage bag parachute for recovery.






A B6-4 is about as big an engine as I can go in this field. The Quest NIKE SMOKE is perfect match.

This rocket never fails, with a strong plastic fin can and thick metric tubing it'll be around for years. Highly recommended. I would guess the altitude was 375 feet.




This is not the Estes Pop Fly rocket.
It's my own version called the BATTER UP! using a bat and ball from the Dollar Tree store.
The fins are prints of baseball cards sandwiched over 1/16" thick balsa.

After reading reviews on RocketReviews.com, some fliers couldn't see the baseball after ejection. I added a streamer to the ball. With a B6-2, ejection was right as the rocket was turning over at about 250 feet.

Although I didn't catch the ball at recovery, everything else worked as planned. Except the parachute didn't fully open.
I haven't seen this before, the parachute blew right through the middle of a wadding square! It held the chute closed by reefing the shroud lines.

Also flown:
The FlisKits INTERLOPER with a MicroMaxx engine. High and fast with streamer recovery.
