how perfect does it have to be
cman:
A wise gentleman, who has just been inducted into the AMA hall of fame told me: "Warps are here to stay. Learn to live with them."
In the 40+ years since Tommy Thompson told me that I have learned to build pretty straight, but sometime you will have everything as straight a it can be, then you go to the field and the sun hits your baby......... It's warp time. And that is not warp speed.
Twins can be straight, but even warped they fly great.
Bill.
PS: Bryant A. Thompson - one of the good guys. wr
