First, to be fair, comparing a Profi 4000 to a 9303 function to function is not even close to the same level of radio. If you can get a Multiplex 4000, most of the mid level distributors for Hitec do not have them by the way, you will pay $1000.00 for a radio that is an incredibly flexible system. However Hitec will only be importing them for a short while longer, (See their web site) they are special order only if you can not find one at a dealer. Who is going to support this product when they are no longer available? The 9303 on the other hand is a 500.00 radio system, which with its necessary limits on channel switch select ability, is probably one of the most flexible and intuitive sailplane radios on the market. The channel assignment issue referred to below is specific to the sailplane programming and is an advantage not a limiting factor. It allows a six channel rx to be used for a full house sailplane with the six functions normally used for same, if your friend is only using a five channel rx, it should not make a difference unless he has more functions than the rx can handle in the first place. You have a choice of elevon wing type, normal, or dual flap,(separate flap servos for each flap.) Secondly, the channel assignment is arranged the way it is to put commonly mixed sailplane channels adjacent to one another in the data stream, to minimize synchronizing delay.
My advice is to purchase new JR 7 channel R770S rxs for his additional planes to get the most advantage from the 9303. That way you will have branded equipment designed to work together, they are super small and capable of PPM or PCM modulation. John D.
