I have a number of 401's which suit my pocket, abilities, and they work well.

I've just finished sorting a second-hand Hirobo Lepton which I bought with Futaba servos and gyro. Upon setting up the LED is lit all the time? This I know from my other 401's not normal.

The only differnce is that I'm using a Spektrum RX which is controlled by a Spektrum module in my Futaba ZHP WCII.

On the bench the gyro does seem to work - the LED goes brighter or dimmer depending on whether it is rate or heading hold; rather than off / on / etc; and the servo centres or not.

Also the radio is powered via the BEC circuitry from the Castle Pheonix ESC.

Thoughts / comments anyone??

Many thanks

I'd Rather Be Flying!!

Try another gyro to verify the current gyros condition.

Solid light - it is in heading hold

No light - it is in rate mode.

Blinking light - not initialized properly

Note- the 401 MUST be initialized in HH mode to function properly.

If your 401 doesn't function like I wrote above, I would suspect it to be a Chinese counterfeit 401.

I have read that even the counterfeits have gold plated pins...ouch.

Remove GAIN wire and connect a servo instead to verify THAT channel/switch function.
