Hi guys,

I now have 6 flights on the E5 and I like it more every time it flys.
Still only doing basic stuff (circuits, fig 8s, slow piros) as its my first heli bigger than 450 and I'm still getting used to the way it feels in the air and responds to inputs.

A question though, I'm still running the setup as posted above, i.e. 120HV ESc set as multi rotor and with the aux cable set as engine rpm and connected to the FBL.

In the Ikon I have governor set to 2100 rpm and switched on for all 3 banks. Plus "motor is electric" ticked in the governor gains section(advanced view). I checked rotor headspeed with blades off before the maiden flights and the tacho showed 2098rpm which I thought was good. I haven't checked headspeed with blades on in the air.

I've been downloading and reviewing the logs from my 120HV.
And noticed that the log shows around 2000 rpm average and 2145 maxm rpm during a flight.
Given that the Ikon governor is set to 2100 rpm I was expecting the average rpm to be close to that.

I've checked the gearing setting in the castlelink software and its correct for my 12/119 mainshaft gearing.

Have I set something up wrong, am I misunderstanding how the governor function works, am I misinterpreting the data, is the CC data reliable?
I've attached the log from my last 2 flights if someone can have a look at them for me.

Your feedback will be appreciated.

Cheers

Hey guys,

update on my previous post with the question about the CC Edge 120HV logs.
I had 2 more flights this morning with headspeed on banks 1-3 set at 2100, 2150 and 2200 respectively.

Looking at the logs I can see in the RPM graph where I've switched banks and the headspeed is close to the governor setting. The peaks and troughs in the graph can be accounted for by changes to rotor loading.
So, I'm happy that the governor is working fine and the headspeed is being accurately recorded in the ESC and reads correctly in the graph viewer.
Then, while looking at the graphs, I realised that the average RPM in the graph was low compared to the governed headspeed was because it was averaged over the entire powered up time of the ESC.  Which included a large chunk of time at zero throttle.
When I limit the graph to the length of time the rotor is turning the average RPM comes up to the governed headspeed.  Wish I'd worked that out before I asked the question.

Ok, puzzle solved, maybe this post will help someone else who has a slow day sometime...
