Sean,
Just to be clear, the Royal Evo is not a tray style transmitter, it's a standard format transmitter. The MC 4000 is the tray style transmitter. The number one misconception regarding this transmitter is that it is too big to be comfortable. Wrong! The 4000 Tx is 1" thick. The typical distance to the top of the sticks (wrap around distance is you like) is similar or LESS than a typical Far eastern tx.
One the other hand you get 12 fully proportional channels, and unparralleled programming capability ( I mean in a different league to the far eastern stuff). So if you need more channels and more mixing and switching capability, don't be put off by the size until you have tried it. It's a non issue.
Regards,

John.
