I am not very good at building but do you think it might be worth recording and posting a build ?
Independent of whether or not you are good at building, you are making smart decisions about the use of rubber motors!

As it happens, yesterday's mail had a quarter pound box of 3/16 tan sport rubber and bag of 36 feet of 1/8 tan sport rubber from FAI Model Supply.
They won't see much use in planes though, but rather in balsa wood boats and submarines.

This book has an account of the spectacular destruction of a large 50 inch span model when the rubber motor either broke, or came off the propellor hook, would have to find it in book to be sure what happened.
