Did I mention I build and fly rockets? This is Super Bonbon, my L1 high power rocketry cert flight, launching in the Mojave Desert in the summer of 2021.
Hybrids are a bit more complicated (one reason why I like'm), but not difficult. A big issue (especially in Florida summer) is maintaining cool bottle temp. Otherwise the density causes poor/degraded performance.
Timing ignition isn't an issue as long as you can see the venting (look left/above the gold band in my pic)
Clusters *require* high current - best with a relay/battery at the pad. Clip whip = friend
For clusters I was launching with a lawn tractor battery (lead acid, about 1/2 a car starter battery) but the relay is a good idea. I used the sturdiest speaker wire I could find, but that did probably limit the current quite a bit. I was worried about following the letter of the regulations and avoided fully arming anything while still at the pad.
