Pro-Lines design queues consistent with all HardDrives are ventilation louvers found throughout each body. Emulated after full-scale off-road vehicles, each can be cut out allowing for air to flow more effortlessly through the body. This creates less airtime when flying over jumps. Less airtime equals more time on the ground. And, more time on the ground equals reduced lap times and greater consistency lap after lap. A fresh new design has arrived for the off-road market from an award winning and longtime absentee from the off-road market. Now you can pick right up where PROTOform left off with the new HardDrive body designs. · Extreme ventilation found throughout the body · An off-road first in over 10 years for PROTOform · PROTOform decal sheet, window masks included, Paint-then-Peel overspray film · Made from genuine GE .060 thick Lexan-the toughest on the market
