Madcow Bomarc Build, Part 1, Parts


This will be a fun build. I've always liked the Bomarc design ever since I had the Estes Citation Bomarc in the mid 1970s. I picked up that kit at the Estes factory.
This is a very heavy duty model. The centering rings are die-cut plywood. 
The fins are laser cut from basswood. The parachute is 18" nylon.
The ramjet nose cones are balsa, the tunnel strips are balsa.

Parts of interest:
Two 1/4" thick walled launch lugs are included.
The shock cord is a thick braided Kevlar tied to a long white nylon cord.
A 6" square parachute protector.
Black plastic nose cone with a long shoulder.
18" nylon parachute.




One of the more interesting parts is the main body tube.
The walls are very thick at .05".
It is almost a BT-60 diameter. The outside diameter is 1.6". A standard BT-60 is 1.637" diameter.

  1. How thick are the basswood fins, just out of curiosity?
