Noseweel steering motor identical, follow up pot not. Yes they boobed and tried to fit a Phantom one to a Tornado. Problem with Tornado is that it was electrically centred. After take off would do a built in test but then would not detect central ( bloody micro switches), so would not retract. Phantom was mechanically centred as weight came off and leg extended a roller running in a V grove, roller would run to bottom of grove locking leg central ... simple and it always worked.
Only problem with Phantom was stick to seat interface ( pilot). Nose steering de- energised by microswitch operated by handle in up position. Pilots wanting to do ‘maxi welly’ take off wanted to keep left hand on throttle right hand on stick. So some would select undercarriage up before take off relying on weight on wheels microswitches to stop aircraft dropping on its belly. They would then roar off down the runway hoping they did not hit a bump but not realising how the system worked they were blissfully unaware their nosewheel steering was off until the aircraft drifted and they tried to use it. I was personally involved with 2 cases where this happened, one resulting in the aircraft departing the runway at high speed, Of course in Phantom days we referred to weight on ground switches but after many years because of the acronym Tornado days referred to weight on wheels (WOW’s)
