Love CTI, Hopefully this load and the 3G 75mm L1350CS I demoed will be certified soon! That load put my 23lb Gizmo XL slug to 6300' Love the 3G 75 loads.
Dave:
Yup I'll be at all three launches as well, Which launch are you planning to do your L3 at and what motor?
I hope to do a shakedown flight on a K675-SK at NERRF with an L3 attempt with a M2250-CS at LDRS. I don't have my 75mm hardware yet.
Curious, do you have a preference for piston or no piston on the Gizmo XL after flying both?
I would run some data (sims) on that K675. If yours comes out anywhere near the weight of mine, that will be a bit low on "umph" (no science behind that thought by the way). If you do fly it, let me know how it goes. I would love to know it can fly on things smaller than an L. (I have a 3 grain75 L Skid that I wanted to fly in mine, I think it's a bit underpowered for the 23 pounds......so did CTI)
I would in fact prefer an L motor for the shakedown. I was just looking at what I currently have and ran them through Rocksim. My estimated build weight without epoxy or paint is 22.9 lbs. This includes chutes, shockords, avionics, everything but the motor. At that weight rocksim shows 2600 feet on the K675 and 7320 feet on the M2250. A 3 grain 75mm L would be more appropriate for the shakedown. I'll run more sims as I get closer to launch time.
