I understand what Robert wants... However, like I said, "the viability of the flight with a P motor has yet to be determined"... We will know for sure when and if it pops up on the Featured Flight page...

True dat.

Fred,

Apogee was 900'
The 2 PICOS were set for drouge at apogee..then main at 800'
The one RRC3 was set for drouge at apogee plus 2 seconds..... then main at 700'

This was the Patriot's first dual deploy flight...separation at apogee with a 40' cord and drouge chute...main chute at 800' along with the cone separation at 800' with it's own cute.

At it's next flight on a N motor altitude will be 2200' and we should see the dual events more clearly...

Thanks for watching the flight and postiing...

What do you use for the main and drogue chutes?

I thought an RRQ150 was big..

Kenny,

The pad weight for the August flight was 200 pounds with the CTI M6400
Drouge chute was a 42" Skyangle wrapped in a nomex blanket. Drouge shock cord 40' kevlar from ebay to fin can. 36" shock of kevlar from ebay to drouge chute.

Main chute 30' Rocketman packed in a Rocketman deployment bag..the chute apex is attached to the inside of this bag.... a 32" Skyangle chute is used as a pilot chute to pull off the bag...this pilot is attached to the outside apex of bag.
Tubular kevlar cord 15' from the ebay to the main chute.
The RM bags have 3" sewn loops inside and outside the bag tip...apex.No cord used between these loops and the main and pilot chutes.

Cone chute Skyangle XXL also in a RM bag..attached as is the main...uses a 24" pilot chute. This cone chute attached directly to the cone ubolt...no shock cord.
Both pilot chutes that are attached to the bag apex are protected with nomex blankets.

I will recheck the descent calculations and post them with the rocksim for this flight.

Absolutely picture perfect flight Tom...
You most certainly pay close attention to the details. ....

That's very pretty. Do those fins look larger than scale, just curious.

Yes the fins are upsized to ensure stablility. Can't recall if it was 1.25 or 1.5
