Warranty Details
15 Days Warranty
Covered against carbon delamination flaws and precise CNC machining defects for 15 days from the date of delivery. Valid claims will receive a direct replacement.
Voids Warranty: Carbon snaps, fractures, or arm breaks resulting from racing crashes, high-velocity gate impacts, ground collisions, manual drilling/modifications, or exposure to harsh chemical solvents.
Installation Note: If your 20x20mm 4-in-1 ESC does not fit flat inside the frame due to an onboard low-ESR capacitor, please desolder or reposition the capacitor off the ESC PCB board. It is highly recommended to bridge an external 50V 470uf (recommanded)capacitor via a short lead wire to maintain clean power filtering.
