cafusin, you really dont need to move the tank, and if you go to page 75 i have some info on mounting the 100. i havent time now but ill dig up more info later and get back to ya

just keep the questions comming and youll get more answers from everyone here!!
ps. the mount in the pic on page 75 is a ucd60 size mount (great planes 60-120 size)you really dont want to mount it on the stock(small)mount.
