Darryl, Just this week videos were posted on this site of both Q40, and 426 Quickie practice at the Old Julian Airport site. Look under Pylon Universe- RC Pylon Racing and open the General Racing Discussion section. Then open the OJA Q40 & 426 Practice thread. 426 Quickies do about 165 mph, and Q40's (event 422) almost 200 mph in level flight. Good luck, Greg
