This has been about the best thread I've ever seen on the 2v4s debate. I am sorry I didnt fork out some extra money and buy a saito 180 for my Funtana 90, instead of the 2s 120 it now has. I have also recently seen a 4s powered Funtana 40 being pulled around by a Saito 91 and the throttle response and 3d capability was clearly far superior to a Fx 61 powered model flown on the same day.

However, it seems that 4s hasnt taken over in the larger gas powered model arena. Chip H's double vision for instance, 3d's very well with a 2s 50cc (judging by the promo video) and al the TOC style planes use big gassers. Does the gasoline guarantee better toque and throttle response. Isnt it possible to tune a 2s to respond more like an electric/4s motor?
