The smallest composite staging system

[mbeels]

The flight computers are slightly modified versions of the FlightSketch Sport we are developing.

Those sound very interesting!

How about a 13mm EX-C motor powered 2 stage with GPS telemetry.
We put it in a shadow box to present to the TARC teams that got disappointed watching large motors fly while they were flying these small F motors. It demonstrates how hard it can be with small projects that have a goal.
It uses a timer for staging powered by a super capacitor.
The dual deployment altimeter runs on a 1.2V NiMH battery.
And the GPS system runs on a LiPo battery.
And the Altimeter has a 90dB buzzer to find it after the GPS gets you close.

Impressive!

What GPS did you use that fit in a 13mm tube?

This something I am really looking forward to do with the Quest Q-Jets A-D......I'm waiting for FlightSketch to come out with their Sport or Comp, Russ said that a firmware update would allow one or the other to be used as a staging timer

Green Monkey13mm cases?

Glorius:

is that a Green Monkey13mm case? You have a schematic and parts list for that staging timer?

I haven't tried staging, just made bigger motors
Rx 13 mm D40 20 N-s

18 mm motors, including an 70 N-s F22 with 9" of propellant
