I'm somewhat new to rc heli's, currently I have a couple of micro's,a 3 channel co-axial, a honey bee f/p (004),and a hbk2 that I have never even powered up. I got hooked on the honey bee f/p and put more money in it than it cost new. I have "EXTREME" metal parts (blade grip,swash plate,fly bar paddle control frame,and metal tail motor mount)I also put a HBK2 battery hanger and skid set and HBK3 fly bar paddles on the bee. She flies really smooth. However, I now get about half the flight time out of the 7.4v/800mah li-po that I used to get. After a few minutes she can only get about a foot off the ground. I would like to switch to my 11.1v/1000mah li-po"s. Can someone recommend a brushless motor and ESC that is not overly expensive and will bolt on with little or no modification required? Will I need to add or change anything else when I go to a brushless set up? Also can you recommend a upgrade set of main blades for the bee? Again there are so many choices and I'm not sure what will work and what won't. Any part #"s and all of your help is appreciated. Thanks. KJ
