Higher c battery has a much higher voltage under load which allows you to get the same power at lower throttle and fly longer. It's like using a bigger turbine and throttling back. With a higher c battery you are not at full throttle as long so the flight times are longer. A 50-65c is totally different than a 15c, especially in an edf that requires a lot of power.

If higher C cells would only cost more $$ things would have been fine, but they cost in weight and life span too. Heavier with much shorter life.

10 years ago we set up our planes to fly for 15-20min as the batteries only allowed that. This made the setup easier on motor and batteries. You also needed to think twice before buying a setup as you needed parts that work well togeather. Now days we lost all sense of what's working and you press buy on the hobbyking site adding higher C cells to compensate. hm... back then you did't even need to balance the cells.
Most tend to like the stock servos, but have problems with the board. I always buy the kit and install HS65MG servos in my foamies, I feel safer that way.
my TP yellow label over 9 years old and never charged.
