For the past several years I've been using the Cirrus CS-30 BB servo to activate the 35mm cameras in my payloads. A few months ago I discovered that Cirrus has discontinued many of their servos, including this one. Most of their current line of servos are smaller, but also have much less torque. I've finally found one that will work as a suitable replacement, the CS-20 HP. The torque is sufficient, and the speed appears to be comparable. The output gear is larger than on the CS-30, so it won't fit my existing hardware -- but this won't matter on new payloads using new hardware.
Also, it appears that Aerotech 1.88" airframe tubes and couplers are compatible with the tubes I've been using on my smaller camera rockets. I had been getting tubes from Vaughn Brothers Rocketry but they went out of business last year. Totally Tubular has the AT tubes and couplers. Only problem so far is that they seem to be pretty slow about answering emails, so I haven't been able to place an order yet.
