Hey fellow aviators, I just got into the hobby and have built two different FT models but just picked up a Sky Fly Max ready to fly for $50 to get me into the next level of performance from my simple cub and 4 channel. My question is how to get some more efficiency out of it and longer flight times. Its currently running an 1800 3c and a 9" S-2 Master Air Screw prop. Can I run a bigger battery and maybe a different prop? how about a 9" three blade to bring the rpm down? Im new at all this, having a lot of success flying but don't know a ton about all the other little things. Was getting 15-20 min out of the 1800 battery in my simple cub, RIP.
