Airspeed v3 not working


I recently bought(esprit) an airspeed sensor to use standalone.
It is a v3, however it is not reading any speed at all.
even with short 1" pieces of tubing connecting to the pitot there is no change from the 0/zero reading.
The pitot tube appears to be good,
centre hole is clear to see through and the 45 one can blow to the side holes.

Any suggestions ?

Hi, if you blow gently into the end of the pitot tube, does the sensor not flash a non-zero number?

If not, the first thing I would check is to make sure you have the hoses connected correctly (not backwards). Please check the hookup diagram in the manual here.

yes, tried blowing soft, fast and swapped the tubes to no avail.

Hi Lenny,

if you connect a rubber tube to only the + input of the sensor (shown on the label) and blow into that, do you get a non-zero reading?

If not, the sensor is defective. Please open a ticket with us at and we'll get it replaced for you.

I opened a ticket report 616213
however no response from Eagletree company.

What should I assume ?

You probably haven't heard anything because the folks aren't back and ready to get at it again after returning from the big RC Show in Toledo, OH this past weekend.
