you can get them on Ebay for like $20 or so.(ek2-0704B)
This is the one that i got BUT you will NEED a Third Ch for this one.
for usen just your 2ch radio you would want this one
ek2-0704 for 2ch radios you cant turn it off.(but its hard to find this one now)
For My radio all i needed to do was....
just plug it in to Ch1 on the RX
the yellow wire to Ch3 on the RX
Flip the switch on the Gyro to REV
turn on the Rc.. Wait for the Gyro to set its self about 3 seconds
on my Tx my datarate for ch3 is set to 28%
!!!! DO NOT GET IT WET !!!!
unless your good with electronics you Could take the Gyro apart like i did and Coat the boards in it COMPLETELY
with Epoxi
i even covered the Delay and Limet controles with epoxy.
i set the gyro limet to full and delay to its lowest BEFORE doing the Epoxi waterproofing.
DON'T cover the NOR / REV switch as you might like to still use this at some point in time.
this is the Epoxi that i use to waterproof with
Dont mount the Gyro in the CENTER of the Rc!!
Here is a photo of my Chassis and you can see were its mounted at.
