YGE and VBar Gov Setup Instructions

[Mystic3D]

Guys,

This should be pretty close as I verifed some of the instructions from YGE that were cryptic..
This is for Vbar 5.23 and YGE 120HV/160HV Ver. 4.23 with VBar Support.

Be sure to review Mr/ Mel's video on Vbar Gov Ver. 5.2 as the motor start setup is different than it was for Ver 5.1

4th Revision

Works Perfect!

Maybe this is a newer version.

[Mystic3D]

Yes it's Ver. 4.23, same as instructions with phase sensor output

So, is the Vbar adapter communicating phase sensor data to Vbar from the YGE ESC?

[prototype3a]

The new (ver "23") YGE hv (90hv, 120hv, 160hv and possibly the 60hv) escs can communicate rpm data to the v-bar through the programming lead when that adapter is used.

[Mystic3D]

The YGE 120/160HV new version that shipped end of last month uses the program cable via a special adapter to output phase data to the Vbar Gov Sensor input.

So yes, you do not need the Hyperion Sensor in this case. Also it looks like it outputs "cleaner" data as I do not get as many "phase sensor" errors.

Revised the PDF, it should be Very Close as I got some clarification on the process from Pete at Electro RC, some of the YGE german translation was cryptic.

Version 2 of the instructions attached.

Changes:

Plane Fast + Plane Fast Method
Turn Freewheel = OFF
Proper calibration of Motor Stop and Max Throttle

For the initial startup speed, you can set heli low, middle, or fast, the secondary start up speed is the response for external governor.

The YGE documentation was trying to imply that any of these are valid (not just heli middle - it just so happens that this seems to work for most setups). This will give a smoother start yet still allow for fast recovery for bailing out of autos.

Thanks for starting the thread Mystic!

I might be overgeared and running too low throttle to get Heli Middle + Plane Fast to work properly. In this configuration the startup is great, but the throttle response seems to stay in Heli Middle so the VBar Gov does not work well.

Not really possible for me to drop a pinion in a 700E so unfortunately the only thing I can do is go with Lower kv Motor and will try that.

Yep, waiting on reply from YGE...

Is the procedure the same for the mini Vbar? As I understand ground should go to RX C ground and signal to RX A signal (top).

The ESC Procedure should be the same. The instructions do not really cover VBar wiring other than for the purpose of programming the ESC and the Phase Sensor cable.

Not sure about how to wire Gov on MiniV

I will try today and will let you know if it works.

YGE 120HV v4.23/V-Bar Gov 5.2.4/Henseleit TDR

Bench testing:

I performed 2 extreme tests to make my observations.

1. In Plane Fast - Gov Off x3 - Plane Fast = Very Fast Spoolup. With Collective Control set to On in Gov II tab, I noticed that when adjusting the high throttle endpoint with the slider the response was extremely quick and I found a value of 94 for my full throttle endpoint within seconds.

2. In Heli Slow - Gov Off x3 - Plane Fast = Noticeably Slower Spoolup. However, with Collective Control set to On in Gov II tab, I noticed that when adjusting the high throttle endpoint with the slider the response was very slow and finding my endpoint value took quite sometime. When I did eventually find my endpoint of 96 it seemed like the motor was hunting, only very slightly, which is probably why some of you reported that when flying in lower head speeds it took sometime for the V-Bar Gov to catch up when performing collective punch outs.

My conclusion is that this programming method is simply applying Heli Gov or Plane Gov settings and not invoking the Heli Spool Up with Plane Fast response as we would expect.

Has YGE been made aware of this?

Ok, tried about every combination with the YGE but running is incosistent and a hit and miss affair. Went back to the HW Pentium and all is good.

Plane Fast + Plane Fast is definitely the program mode you want to use. I was worried about spool up myself with Plane Fast + Plane Fast, but after some test flights today I can confirm that the kick is very, very small on my TDR and certainly did not fold my blades. :thumb up:

I contacted Heino regarding programming of the YGE with V-Bar Gov and this was his reply:

"If using Plane fast for start up, you need no procedure e.g.. Plane fast, Gov off x3, Plane fast. If you can live with Plane fast for start up than is enough you program only Plane fast.
If you need Heli middle for startup than program Heli middle, Gov off x3, Plane fast. The controller switched to Plane middle or Plane fast after spool up to 75% throttle.

Best regards,
Heino"

I wonder if V-Bar is taking control to early and therefore the ESC is stuck in Heli state????

I have programmed Heli Middle, Gov off x3, Plane middle (suggested by Heino. He said Plane fast has a very high amp consumption due to extremely fast response).
I need to flight test these 3 different modes to see the difference and will report back with my findings.

I am pretty sure it means overgeared. In other words VBar takes over throttle control at 600 rpm and then uses throttle to control the ESC. I know in my case on the 700E when I spool up on the bench I am at 25% Throttle.

i cannot go down from an 12T to 11T on the 700E with Slant Pinion so outta luck.

I read elsewhere the YGE likes high throttle, geared to operate at almost full throttle.
This would explain what I see as I never get to 75% Throttle.

Too bad this 75% is not adjustable.

How are you guys setting your max headspeed in the vbar? I noticed a big difference today just by changing my max headspeed. I initially was using the std mr. mel calc to set what to keep my max hs. Instead i found that using the numbers he posts for vbar external gov were a bit too low to use as a max headspeed, so i instead increased the max HS by another 100 RPM, and was extremely suprised by the results. This worked out great. I checked it with a tach and could see that the new 100% HS was holding perfect and more importantly I even saw a drop in motor/ESC temp. I highly suggest everyone experiment with raising your max HS because tpo low a HS could be causing you to run very low throttle % making your heli run unnecessarily warm.
