The bolt has to be soldered or welded at the joint that I snapped by over tightning.Part of the deck will have to be removed to gain access to the bolt.The sub has all electronics by Robbe,battery ect.(No TX or RX.) I purchased the sub from a professional model maker.It makes a great display model.
