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.
The HK401b did not work for me. Also tried to modify it (following mods I found on internet) but didn't work either. For some people it has worked as goog as a Futaba 401, for others it hasn't work. Your choice...
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
