Default What do you think of my Eagle Tree shots?

Hi,

I'm starting inverted flights and received yesterday an eagletree... A bit risky, cause I crash often; but I made some shots / captures with my TREX SEv2.

What do you think of theses specs ?

The installation


Chinese mod (thanks Kevin)

Thanks for your feedback

Cédric

The headspeed sensor is the MOST important sensor on the eagletree, it basically tells you everything you need to know.

oops, I need to get a HS sensor by the way

Which one is the best? optical ?

So to sum up :
- amps
- rpm

and volts ?

This is crazy


Brushless Motor RPM Sensor

Tiny sensor measures RPM by simply connecting a wire from one of your brushless electric motor leads to the sensor. This connection is just a splice (not inline) which simplifies installation.

The eLogger V3 supports up to two Hall Effects or Brushless RPM sensors! How does it works ?

It works the same exact way your esc does. Read this

Thanks a lot for the support HFG. Much appreciated.

Do you think that I can get some stats about my lipos ? are they still good ? are they close to "death" ... with the eagletree?

I base my lipo health using my HS, when the packs start to go south i can see the HS dropping. The pack of mine that died last week dropped to 2700 (i have my head gov'ed to 3100ish) the flight before it died completely. Hmm i might actually have the data from that crash.
