The now famous HK401B is known to have the same characteristics as the Futaba GY401. In fact we guarantee you wont know the difference! No tail drift, excellent hold characteristics and a level of reliability only found in $100+ gyros. Dont risk your heli with other cheap Gyros when the HK401B has been proven by thousands of pilots to be stable and accurate in a variety of temperatures and helicopters.
Compatible with both Digital and Analog systems
Minimizes rudder trim changes caused by wind, other meteorological changes, and varieties of helicopter attitude changes are automatically cancelled.
Sensor vibration proofing
Simple sensitivity adjustment
Digital proportional RIC system
Operating voltage: 4.8V ~6V( common for receiver)
Operating temperature: -lOL r-.rf-45 C
Dimensions: 28x26x20 mm
Operating current: 80mA
IMPORTANT: Make sure you isolate your Gyro from vibration. Use double sided foam tape and never use cable ties. Vibration will cause harm to the Gyro and degrade performance. Manual found in the files section below.
I have used both on my HK450GT helicopter. They both work great as long as you isolate them from vibrations very very good. So you can get any of them, go with what fits you best. I did not notice any big difference in performance in mine.
I have seen a few posts asking about the AVC AND NOR settings using the tx9 and have seen a few people complaining that they have no control in AVC mode (head holding). The settings have to be above 50.
Set to these setting and i have found this gyro works very well and you can switch between head holding and rate mode with no problems using the switch.
UPRATE AVC 068
DNRATE NOR 060
Make sure you have the other gyro settings on the gyro set up correctly too ,as the instructions.
yes this way: the input of the gyro to the steering channel in the receiver.the output of gyro to the steering servo.the gain wire of gyro to 3rd channel and program this channel to 4o%-49% normal mode
i figured for the price i couldnt resist trying one of these and i am not dissapointed this things works great just as good as my 401 futaba gyro you need to look at the mods section on this as i had to do that but the little time i spent doing the mod was more then made up for with the low price and great performance

I bought this gyro to try out for HK 450 it does very well ,hold the tail is solid with JR servo DS290G, First I received, inside board was sloppy & I try on heli it doesn't work, then I Open in back gyro I sim double tape to hold them inplace worked very well fly good,good for $ too
