Hi. A couple of years ago I purchased a KDS 900 Gyro for my first 450 Heli build. Long story the build was delayed for about two years and within that time I lost the gyro manual disc. I have the programming unit but It have no idea how use it or what the settings mean. I've been scouring the internet for days now for a manual or guide for this gyro but I've found nothing, even KDS's own website has nothing to offer. Is anyone familiar with this unit?
