Comments
@Hooks, I don't think your comment came out of the blue. I haven't seen it being announced at the Hobbyking website that this was a one time gig. Since you post this here (and if I am correct you are a shop owner) I think you know more.
@arashi, You probably mean difference between FY-20A and FY-21AP(FY-21A)? As far as I know, the FY-20A is a Flight Stabilisation system and the FY-21AP a Flight Stabilisation System and AutoPilot.
What exactly are the differences between the FY-20A and FY-21A?
Maybe some distributor that was afraid of loosing customers contacted the manufacturer/supplier, who in his turn became afraid of loosing distributors which made him promise to the distributor in question that they will not supply to HK anymore?
Has happened before if I read the various forums.
This batch is the last batch hk will sell.
Now also on the site is the FeiYu Tech FY-20A Flight Stabilisation System for 102 or, if you wait a little, for US$ 82.68.
The FY-20A is a flight stabilizer for fixed wing aircraft based on inertial motion sensing. It utilizes a 3-axis gyroscope and 3-axis accelerometer to control the aircraft attitude in all 3 dimensions. The unit can be activated or de-activated via a spare channel from your receiver.
