Unitl I saw this buildup on another forum, I was happy just to live with my inaccurate pack. After seeing Scootch's work and getting ideas from it, I bit the bullet and built my own. I modified it to fit what I have (I used Crashmann seed trays, stinger, tool box, radio/ Sci-Fire cistern and exhuast port) and used this thread almost step by step to build it. I made a slightly different frame but it was scootch's in depth build up that got me going and got me through. I have to do touch up painting and weathering. After that's done, I'll post pics elsewhere for you guys. At any rate, I wouldn't have a decent pack if not for this guy and his amazing build. THANKS SCOOTCH!
