2.25gm Walkera 2.4GHz 6Ch RX
Now its official. The Walkera 4G6 2609 RX can be separated. One of the boards is the gyro, the other one is RX only (that is the board with all the servo connectors). After seperating the RX board is only 2.25gm (see pic below). As is the thing has 5 channels but it might be possible to use the gyro sens. channel as well, making it fully 6 ch.
The RX will be used in my BLiX-Twin.
Here is a short video with the seperated RX alive:


Hrmm makes one wonder if any of thier other ones might be splittable too. Found your Youtube video when I went looking for alteranative Walkera RX’s. Be nice to have a small backyard Ele plane for days when the Heli is down or it is too breezy to be enjoyable..
Is it possible to take the gyro out of the 2609 and use just the gyro (with a spektrum receiver)
yes, its possible, but I have not done this myself yet. You can check RCGroups.com (micro helis), I believe there is someone there who did this.
