I love my WB! It flys real smooth, and The 91 FX I have in it is a good match. Great pattern (I fly advanced and this is my primary plane) and I am going to try out a 15X6 prop next to play with the 3-d stuff next. I put flaps and two extra servos on mine, and I came out at 8 lbs. with out the flaps it would have been about 7.3-7.5 lbs, which is about average from what I have seen. It flys Knife edge loops and hovers at 8 lbs with the 2C, and the flaps are fun to play with, and are not at all necessary. I just wanted a model that I could do all the cool radio stuf with.
