I love these threads, because I learn a lot from experienced fliers. Here are my various thoughts on topics touched on in this thread. There are pros and cons to everything. If I had unlimited dollars, I would stock and fly both Aerotech and CTI. Currently, I fly Aerotech reloads 40-120 case for low power, and CTI for hpr. I love white lightning and redline in AT, but opted for the CTI hardware starter sets for 38 mm and 54 mm. For $110 or so (38 mm) you get the 3g / 6g cases, 2 spacers, and the proDAT delay tool. This allows me to fly any CTI from 1 - 6 grains. Try to beat that. Similar for CTI 54 mm. I bought from Apogee (not particularly cheap vendor) because with no tax and bonus points (essentially 10% discount) this translates to nearly 20% discount. The starter set prices were really appealing to me. Loading and cleaning of CTI are a snap. I also love the skidmark from CTI. I will eventually get AT hardware, but for now am spending on tracking, 75 mm rocket and equip., better electronics, while currently purchasing K and L reloads. This all adds up. I launch low power with my kids. In one day, we can launch 14 or more motors, so I am a bit cost conscious there. I buy from Hobbylinc. for low power. They offer great prices, but limited AT reloads. You can get a G76-G reload for $10.69. This will fit the 40-120 case (also cheap from Hobbylinc). Hobbylinc does not offer the AT 120 case, nor reloads for it such as G77-R or G79-W. Green Mojave is not my favorite, but I will take the savings. One thing that I have learned buying hpr motors, is that some vendors will charge the Hazmat, and some won't. I won't name these so as to put them on the spot, but this is a big savings. I tend to buy from my local vendor, but buy from him online in advance, because I like to have my motors before showing up to a launch. If I run out, I buy more at the launch. Just look at the total price including, tax, shipping, motor price, and hazmat fee, not just the motor price. Anyway, I enjoy reading these threads. Any more tips, thoughts, are appreciated.
