Twist if you like, a lot of guys do. I buy my servo wire in bulk and clip the servo lead wire and solder on my extension. I used to use the store bought leads/extensions but they should be pulled and cleaned every year and I'm very bad about doing things like that. By soldering on my extensions I get rid of that little problem. I almost never use a Y harness, I have seen too many of them fail, if you must use them try to put them on something like flaps so it doesn't mater if you have a bad one. You buy a high powered radio for a reason, use it, that's why you bought it in the first place. P-mixing is easy and works very well. I have only gotten to program one plane so far with the Futaba 10 and I like it very well, maybe because I have been using the Futaba 9-C for so many years. I also like the JR 9303, both easy to program. At the moment JR has a better selection of RXs you can use so you can save some money but I like the FAST system better?? Maybe?? Both nice radios
