Default A question on Dual Deployment

I'm setting up my first dual deployment rocket and I've done some ground testing.

My setup has two altimeters and one charge for each altimeter / parachute for a total of 4 charges. When I tested each section, I only put one charge in to gauge the amount of BP needed.

I'm using the centrifuge tube type BP holders with Q2's.

Do I have to be worried about one charge detonating the second and overpressurizing the tube, or would it be better to put 2 igniters in 1 charge, one igniter to each altimeter?

I wouldn't worry about one charge destroying the other one..

First dual deploy and using 2 altimeters? Why? One should be more then sufficient and use motor back up for your drogue deployment...

I went with two because I had the room and I like the redundancy it offers.

If you're confident that your charge is adequate, another option is to wire both alt's to the same charge. Is this goin' down in your Wildman?

Yup, I have the wildman DD ready to go. I'm planning on a I255RL next week.
