KDE DIRECT TREX 250 SERIES EXPANDS
We are proud to release the second upgrade for the Align TREX 250 series helicopters, the KDE Direct TREX 250 Series Battery Mount Upgrade. The new upgrade provides excellent strength and support for the front-mounted LiPo and ESC, with a FEA-optimized webbing structure underneath that rivals the original weight of the stock components at a mere four grams. The upgrade includes captured-strap slots and an extended footprint for additional holding strength of the components during quick 3D maneuvers.
