Yeah Racing Wind Pressurizer cooling fan booster

Coming from Yeah Racing is their new Wind Pressuriser, a cooling fan booster for 30mm speed controller fans. Machined from aluminium the part will greatly improve cooling efficiency as it not only maximised the air flow but also acts as an additional heatsink. The booster is made of black anodised aluminium and it is best used in applications that are less sensitive to a slightly higher centre of gravity such as 1/10th drift cars.
