Nothing wrong with Futaba, my first 2 radios were the "F", nowdays preffer, JR/Groupner's "MX22" , the best TX I ever had, still using 2 of them on 36 and 2.4 by changing the back module, a brilliant idea, you can't do with any current radios as my latest "Spektrum DX9", pretty good but no match to MX.
Easy swap of freq.
The first TX job is to cut down the stx to 10mm for better controls.
I preffer the left, it's lot heavier, feels like a real radio.
