I've looked around for a build thread for the Estes Mercury Redstone using the Groen wraps but had no luck. Anyone aware of one?
I did a quick check, the length of the tube in the Estes kit is 19.5" and the length of the wraps is about 19.75" so pretty close. I had to scale the printouts of the wraps at 94% for the circumference to be correct.
