James, I'll bring the Dominator out, aka the test vehicle. And let's see if we can get it work in that one. We'll try for 8k if we can get your payload onboard.

I'm specifically looking for something I can mount new rocket electronics and video recorder on board. I only need to drill a 1/4" peep-hole through the airframe.. If interested, please let me know, I have 4 units available now, and will be building another 10 next week. -James
