Default JivePro, Kolibri, expectations.

Hi all,

I need some metrics from more experienced flyers.

I have a Goblin 380 and a Buddy 380. The configs are as follows:

G380
JivePro 80+
MICROPYRO 380-09
6S 2100 50C SAB
65/75/80 throttle "curves"
120/23 gearing
Governor mode programmed
+-12 pitch
XT60 connectors

Buddy380
Kolibri 90 LV
Xnova TAREQ EDITION 3215-945KV V2
6S 1800 70C ManiaX
70/75/80 throttle "curves"
120/21 gearing
Governor mode programmed
+-12 pitch
AS150 connectors (I know it's overkill)

I am a beginner flyer and only hover and do 8 figures (forwards and backwards). Sometimes I test the hellis by going full pitch up from hover.

What I noticed is that both of them "bog" (I am not sure if in this case, this is the correct term) when going full pitch. This "bogging" is audible, but the helli doesn't seem to mind much. The tail moves about 10 degrees, but it doesn't influence my flight stile.

Still, I am curious if this reduction in RPM is normal for this manoeuvre and electronics.

I have attached the flight logs for both hellis. As you can see, both drop at least by 200 RPM when pitching up hard.

You have "top shelf" ESC and motor. Your are keeping the throttle in the 65% to 80%, so there should be enough governing head room. You are also keeping the collective pitch range very reasonable.

There are substantial voltage drops in the logs. Assuming the batteries are in good shape, verify the battery-ESC wires are not too long, and the connectors are solid.

Hi curmudgeon. Thanks for replying. The dip in voltage seems to be consistent between the two models and it's around 1.8V. That means around 0.3V per cell which doesn't seem a lot.

Anyway I checked the connections and everything seems fine. The length of the cables wasn't modified from the length they came from the factory.

I'm thinking of increasing the RiComp to 8mOhm from 4mohm and the P-Part to 5 from 4. The xnova has 24mOhm and the Micropyro 28mOhm so the increase should be warranted in this case I believe.

Will post back when I get a chance to test.
