Underpowered EFlite Apprentice
 

I recently purchased a new EFlite Apprentice and put the EFlite floats on it. When I took it to the lake to fly,the problem is that is has no power, I have to run it at nearly full throttle just to cruise around. I have seen this airplane without floats at my local flying field doing all sorts of aerobatics with plenty of power. My guess is the weight of the floats is what the issue is. Any thoughts of a larger motor or maybe a bigger battery? I like this plane but would like to have more Gitty-up
