LD Racing Products HB aluminum wing spacers
Developed in collaboration with RPP Hobby/LD Racing Products team drivers Joe Nolasco and Blake Cannon, this machined aluminium wing spacer kit eliminates wing mount flexing and breakage issues on the Hot Bodies and HPI lines of 8th scale kits. The wing spacer kit weighs about 1 gram less than the stock plastic setup and includes all hardware required to install onto your vehicle. Also included are M4x3mm set screws that can be used to fill the empty wing angle adjustment holes to prevent tearing of the side plates during hard crashes.
