The Bottom Bracket Upgrade design provides an FEA-optimized, Aluminum 6061-T6 crossbar construction that prevents unwanted flex during high-torque maneuvers of both the helicopter lower frame section and the connected tail boom braces. Compatible with the T-Rex 500 Electric Series (E/GF/ESP) helicopters the new upgrade provides unprecedented strength in an ultralight design - weighing only 41 grams; and provides far greater protection and support of the carbon-frames in the event of a high-impact crash.
