Leave your boat home,come down and I will take you out in a 280 and a 320 and you will change your mind about the boat,you are still learning and it takes some time,it is a drivers boat not a point and shoot.
1Hyper tell me when and Im going to stick with it. Might as well toss the stick foward with the new power and prop setup and let it fly. It will probably surprise me.
Stick with your Thoroughbred. With the power you have, once dialed in it should be the balls. I'm not sure if you have tabs, but if you dont, you should get them. Drive it like a dirt bike.
