Mein neuer Gyro. Die Platinen sind inzwischen überarbeitet. Leider sind die Lötstellen sehr schlecht. Glücklicherweise habe ich den Kreisel vor Erstinbetriebnahme geöffnet.target=_blank>Gyro HK 401

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...

what is better the HK 401b or HK ga250 and what is the best servo for the hk 450 v2 and is under 10$?
 Paolo 7 points
they both work great the only difference is that the ga250 only works with a digital servo as of this one it works with both and its easier to setup all u need is just a flat screw driver

The gyro is amazing. I used it in the road car model to manage and everything is in perfect order. I recommend this product for its sensitivity and price.

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
