One of the easiest ways I can think of to fire sequentially is this.

Use a Rx output to drive a servo that set up to trigger a momentary switch. The momentary switch, then gives power to a low RPM motor direct wired to a battery pack. Couple the output shaft of the motor to a rotary switch such as this:

Tie the positive output of your battery (6-12V, 2S lipo would be great) to the single pole on the switch. Then, each output from the switch goes to a single leg of each one of these:

Then take the other leg of each of the of the ignitors and tie it to the negative on the battery.

Now, once connected, you control the servo actuated switch with your Tx, triggering the motor to spin which, in turn, rotates the rotary switch sending voltage to each of the ignitors in whatever order you have them wired. The speed at which they fire is simply controlled by the RPM of the motor you're using to turn the rotary switch.

Good luck with it. We'll definitely need to see vids!

I like the rotary switch idea, why not add an arm to that switch, and just use a servo to move the arm, with a linkage? You would need a radio with a selecatable step 3rd channel, like the m11. I may have to give that idea a try...
