This is the HPI Mini Fail Safe Unit. Now you can protect your truck or car from dangerous runaway conditions with this exclusive HPI Fail Safe Unit!
Simply plug HPI's Mini Fail Safe Unit between your receiver and throttle servo for instant protection, just in case you lose radio signal or your receiver battery runs low or while out on the track.
Press the button on the Mini Fail Safe Unit to select the throttle position (neutral or partial brake is recommended) and you'll be able to drive in confidence, knowing your vehicle and spectators will be OK in the event of radio or electrical problems. This is the ideal add-on accessory for anyone using a nitro- or petrol-powered RC vehicle.
