quite an older post.
i am also in the search of full circuit diag. of transmitter for helicopter using tx2b so that i can built a new one for my dragonfly
My E-flite RC Blade helicopter has single main rotor and a rear rotor like a normal helicopter.
It has two gyroscopes for it to maintain stability.
Its circuit board complete with RF receiver and two servos is about 1 inch square and it works at 2.4GHz.

actually you are talking about another heli. i've got a simple dragonfly as in the photo attached. The problem is that ive lost the remote control unit of my heli, & now i want to make one my self. the receiver consist of a RX-2b(smd) chip. i searched a lot but found nothing helping . The ic pair TX2b & RX2b are 5 channel ic used in remote control cars. But in my heli it is used as a proportional controller. My heli works on 27 mhz
