Beware HK401 is not what it claims to be Bloody unsafe gyro to use and unreliable - I lost control of my chopper after 1 minute as the tail started to spin clearly indicating gyro failure ....It appears Ok for the 1-2 mins then all hell breaks loose. Stay away from this garbage.

:S What happened to my text?? I have a small issue with my 401b where it drifts nose left on the HK450GT. Instructions are a little odd, because it states 0% on delay and limit (if running digital servo) on pg 1, yet on pg 2 it says set the limit???

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 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
