Bart I'm as new to this as you, my buying into the smartfly regs came by accident. I called
@stangflyer to talk about radios, that conversation turned into more airplane talk, and how I could run lipo's on the new Sukhoi which have 6V servo's, he suggested SF. I went turbo reg simply because I found it in classifieds, I was impressed enough to buy another for the Ultimate. 2 things I like, first my rx voltage does not fluctuate at all now, where before if I was on stupid rates bang sticks, it would drop 2 or 3 tenthes( no biggie ), but now its a rock solid 6.6 no matter how I bang sticks, even on stupid rates, the other is now all my planes have same batteries. THe savings alone on batteries, will pay for regs in less than 2 seasons.
I see Rob posted, so he's reading, maybe he can chime in on suggestion, in all honesty, you probably don't need the TUrbo reg., and could get by with either the super or the sport. BTW you know my Ulti flew well for over a year on dual nihm set up,if you do stay with nihm, buy good quality packs.
