Flew a successful level II flight!

Continued work on Bull Puppy and received egg finder mini and receiver.

And lots of duct tape?

This question for AIM USB altimeter in particular but may apply to other baro units as well. I understand that pressure increases in the transonic range. That would be until the rocket completes its ascent and slow to below .8 mach.... Is the mach delay on the altimeter set to a time in...

Started a Bull Puppy build

Thanks for the replies gentlemen. 75% of the enjoyment I get from rocketry is the design and build. While I would love to roll my own tubes, I think the smart choice and the economical choice would be to purchase. As for fins, they are overrated. I don't think the RSO would notice. ;)

Thank you

Wondering if anyone might have recommendations on fiberglass wall thickness for a transonic rocket. In my feeble mind I would like to build less than 4" diameter tube. What thickness would you suggest? Thx. Paul

Woferry, Thx for your reply. Your information was posted in a manner that even my feeble mind can understand. Thanx Paul

I can accept the magic part. Most things that I don't completely grasp (and there are a lot of those) I attribute to magic or in a block diagram "something happens here". Thanks Eric

Making the assumption that the JLCR works on a baro sensor, how does it, or does it. ignore the overpressure from the deployment charge when measuring descent? Am I correct to assume it measures pressure when turned on at the launch rail. (I know most of the "assume" jokes)

Level 2 written test completed :)

Yep. Pecos Hank is the real deal. Guest lecturer at symposiums and Universities. I agree that uneducated amateurs endanger others but to each his own. I am not in a prevelant tornado zone (thankfully) but enjoy cloud formations and lightning.

Thank you gentlemen for the remembrance of our veterans who sacrificed their lives for our futures.

CTI. 247H143SS.

I built the Apogee Peregrine for exactly the same reasons you are looking at. I did my Level 1 using an AIM USB dual deploy altimeter and all went without a hitch. Hardest part of the build was getting the epoxy off my fingers. Great instructions and easy to follow assembly. Ready for Level...

Just a simple Level 1 with a first time visit to a club launch. About 2.5 hours drive with my Apogee Peregrine. 38mm CTI 2 grain to keep things low and slow. Chose the Peregrine since I can use it for Level 2. Dual deployment with AIM USB altimeter. 917 feet and 147mph (if I did the math right)

Thank you

I have no idea. I was questioning because the paperwork said phenolic and it appears to be a plastic. Thanks for the info. It seems that the descriptions I have read do not agree with this being phenolic, rather, they agree with your description.
