if the blade is similar to the honey bee 2 ( which i have owned at one time) then no you cannot just hook up the controller to the motor output on the 4 in 1 box. To go brushless on the main motor you have two options, 1st option a2p posted a link showing how to go with all seperate components for the heli ( expensive alternative) 2nd option is you have to take apart the 4 in 1 box of the blade and tap into the channel 3 signal wire for the brushless controller. I believe there are posts on this forum with instructions on how to modify the 4 in 1 box. But i think the picture links in that thread are all dead.
