The Ultra Charge rear wing is made with 1mm thickness poycarbonate and it's an universal accessory that'll fit all 1/10 TC bodies on the market.
The sides of the wing drop down (respect the central flat part) to the limit permitted by Efra of 25mm to collect as much air as possible and generate maximum downforce.
Compared with the 0.75mm wing, which is usually supplied with the light bodies, using the hard wing increases downforce stabilizing the rear of the model, making it easier to drive.
