I've just converted my very old Multiplex Royal (25+years) to 2.4 with the FrSky Tx modification. I was a little bit wary about the results but after some pretty extensive testing on, first a foam electric model and then my trusty 62cc Megawot all seems to be perfectly good. The range is excellent and, of course, the price of this equipment is more than competitive. The Multiplex gear was very expensive when I bought it 25 years ago, can you believe nearly £600, and it has always been 100% reliable so this will give it a new lease of life. Ok, so it isn't computerised 'state of the art' but it will do everything a modern set of gear will do by flicking switches and turning knobs. I like that !!! Anyone else converted anything older ?
Some piccys of the mod.
