Hello

I started to use recently electric set up on my Itegral end realized a fault.

My setup is :
Hacker c50 13xl Competition, Master Spin 99 & TP 5000 V2 10s Extreme

When I check the measurement data with the JetiBox ,
The max voltage was 44.7v .
(which isn't possible , I have connected Astro flight watt meter Between the ESP & the battery ,it was 41.6v).

To see if other measurement are wrong I have tested it on ground.

Not one voltage measurement is correct , it seems to have a offset on average of 3v.
This concerns my in case a cut off as a result of voltage is in needed.
( the maximum voltage I cen set is 32v to cut off ,limited from the ESP ).

I have tested another brand-new Master Spin 99 ESP with the same MAN setting , exactly the same voltage,
Checket 3 different jetiBox ,not a differenc.

A Friend fo mine have the same setup, the voltage is correct but his current amp readingare Are to high with two different JetiBox (107A), Astro flight watt meter shows 74A .

We need help,

What are we dooing wrong ?

Thanks in advance.

Hi Chester,
I have had similar results with the Jeti Spin 75. In my case, the voltage and RPM figures were fairly accurate ..... but .... the amp readings were WAY high. In my case, I was getting motor cuts (slow down) due to over amps...... that just should not have happened ! I believe the fine tuning ability with motor timing and acceleration delay, and the brake options (via the Spin Box) are very useful ..... but the feedback data is highly suspect. Personally, I'll go with my Asto Flight 101 Super Whatt Meter data for amps and volts.

My Feedback: (26)

When using the spin 99 the voltage readings seemed accurate but the peak current read about 15% high compared to the
Eagle Tree Micrologger. A remote logger is the way to go.
