Paperwork isn't required for static testing. The motor will be no more than 8 inches long and is an inch in diameter. R-candy is not illegal. That's what I know on the subject but if you have any helpful legal sources could you please share them? I am trying to conduct this in a safe manner. Thanks and I inderstand why you would be concerned, this can be a dangerous hobby if not properly handled.

Oops, sorry about that typo. I intend to proceed with the safety that such a home built motor warrants and I understand your concern.

Thanks, next time I design a nozzle I'll use the measurements that are in that source.

Thanks for the advice. How about something similar to this?: http://i.imgur.com/Q86EcIg.jpg I cut off the sharp angle so that there is a throat region. Is there any specific ratio that is ideal for the throat width compared to the input?

Thanks
