Zeekio Saturn V

James, what don’t you like about the Skyhawk? Maybe people could make recommendations if they knew your preferences.
Doesn’t matter what his preferences are, the Saturn V is the best for him. Hehe.
Seriously though, if you want a lot of power and spin time, the Saturn V is right up your valley. It has a lot of kickback, though, which is a change from the skyhawk. Sometimes the weight is a little too much for people. I’ve found the SkyHawk to be a bit light for my tastes though.
