Hmmm, tough one to answer on the poll as it is, so I clicked on "other".
I don't believe the "title says it all" actually - What do I prefer, or is my favorite? What do I ACTUALLY fly the most of? "Most" meaning purely how many motors, or "choose most often", or in terms time spent flying, etc? Most dollars spent?
Example: I have a 12 motor cluster rocket that flies on Estes BP motors. If I fly it twice, I've flown 24 Estes/BP motors. But for the vast majority of my flying days, I'm flying AP motors made by AT, CTI, and Loki. On a given day on those days I might launch only 2 to 6 flights. So, in say 4 or 5 days of flying (which might be spread out over 6 or 8 months), I might fly CTI motors only 10 or 15 times. But does this mean I fly Estes/BP "most" of the time? I don't think so.
Given that, here's how I think of it:
I fly AP motors, 29-38mm, impulses G/H/I "most of the time". I guess I fly Aerotech a bit more often than CTI or Loki, but that's somewhat incidental rather than a stated preference.
* Aerotech motors are more readily available, I'm able to buy them at a discount MUCH more often, and I really like White Lightning propellant. Also the HobbyLine offerings are outstanding and economical.
* CTI motors are excellent, ignite fast and reliably, are super easy to assemble and disassemble/clean, have a great range of propellants. Jeroen from CTI spends a decent amount of time here on the forum, and is very helpful & attentive to customer's needs/preferences/concerns - this counts for a lot in my book. If I HAD to choose just one, it would likely be CTI
* Loki is awesome. Super high quality hardware and propellants, a great company to deal with, a dedication to excellence, etc. Scott is a valuable presence here on TRF as well and is very tuned in to his customers - again, this counts for a lot to me. He's also much more of a "one man show" than a big corporation, and I like dealing with folks like this. If Loki was "around" as much as AT, and/or had more propellant choices, I'd fly a LOT more.
I should say that all three of these manufacturers are great, and I'm happy to fly any or all of them. They are each "my favorite" for different reasons.
Beyond "most", I also fly BP motors from Estes in 18/24mm, A/B/C/D impulse. And I fly a fair bit of Aerotech 18/24/29mm, D/E/F/G impulse, but I'm starting to fly some CTI in this range as well. On the other end of the scale I fly 38/54mm J/K/L motors, mostly CTI and Loki.
It's all good.
