My latest Mid powered build

[Luv2launch]

Hi all,
Here is my latest mid powered rocket, its two staged will have a perfectflight MT3G to ignite the second stage.I mainly built it so I can stage composite motors but its first flight will probably be D12-3 to D12-5 or D12-7.Heres some pictures and a rough rocksim file.

That looks great. I'm working out design for a 2-stage mid power also. I have the same timer you have, but haven't used it yet. What are you going to use to ignite your sustainer? I'm considering using a Quest Q2G2 igniter, since they require so little current.

For the D12 to D12 flight I will use the Q2G2's, I might even use them in the 24mm composites I have read on either this forum in the Q2G2 thread or on Rocketry Planet that they will also ignite 24mm ap motors, if not I am planning on picking up a Rocketflite MF igniter kit.I borrowed an MF e-match to use when I flew my Cosmodrome Aerobee Hi a few weeks ago using the same timer.I just need to pick up a streamer or head to the fabric store to pick up some rip stop nylon and make one, this bird sims to well over 2000 feet on any aerotech motor combo I have simmmed it with.
