Although top speed improved to mph with the PVS Laser, 0-36 mph acceleration runs with a light load were actually better with the aluminum prop. Nonetheless, we did see a notable performance difference in the Laser with the use of different plugs. The Laser accelerated quickest (0-36 in seconds) with solid plugs, meaning there was no air coming out of the vents. Performance was nearly identical between the small and medium-hole plugs ( and respectively), both of which were a tad slower than with solid plugs. With large-hole plugs acceleration slowed to seconds and without any plugs the prop was obviously over venting ( seconds).
