What is the dia. of the body tube on this kit? I couldnt find it on jimz's site but I found everything else out. I thank everyone for a responce.
I am not sure, have it on my comp. at home. but I got the info from the Rocsim file at EMRR. if that helps.
My 1982 Centuri catalog says...

smaller version prod no. 5171 is .91 in. or 2.3 cm.
Larger Magnum Jayhawk...2.6in. or 6.6cm.

1995 Estes Catalog...

Pro Series Jayhawk 2.5 in. or 63.5mm
The original Centuri Kit was 0.908 in diameter. If you want, I can create a RockSim version 7 file for a scale model of the Jayhawk. Just let me know the details.
