At Tuesday's (2-16-21) CMASS meeting, several members strongly suggested that I use white glue to adhere paper to the motor mount tube in order to take up the slack on the loose fitting CR's. I glued the paper, did some test fitting and it looks like this is going to work. Thank you all for your recommendations and explanation on how to do it properly. I'm excited about moving forward with the build.
After telling a long time friend of mine how friendly and helpful rocketeers are, he may be interested in taking up our hobby. He was seriously involved with RC planes but was eventually discouraged with the attitudes of club leadership and turned in his wings. Rob has excelled in anything he has ever been involved in. When I raced motorcycles, he was a key member of our crew.
