Vbar v5.2 gov setup

I’ve detailed 9 things to be aware of while programming your v5.2 gov (on the workbench, with no blades installed).  I hope this information will spare you allot of wasted time and give you success in setting up the gov the first time taking out the guess work. 1) The Bailout Arm light will not [...]

Vbar changes and calculations

I did a little more homework and remembered I can plug in two numbers in a calculator within the Vbar software that will assist with determining the blade pitch on a rotor.  Here’s what it looks like: http://www.vstabi.info/en/collective That picture is showing using it for the main rotor, but I thought a rotor is a [...]

Tail adjustment

I am editing this post because there is incorrect.  Tail optimization only has to do with pirouette stops. Today I made a tail adjustment.  Before I say what I did, here is what I saw in the Vbar optimization log.  The optimization left & right values were about 67 & 132 respectively.  I also set [...]

Headspeed efficiency – Great information!!

From Henseleight Helicopters, http://www.henseleit-helicopters.de  They certainly know their stuff and have researched extensively.  This confirms my results running 1900 RPM. In connection with the development of the Rigid numerous test flights with a logger data capture were carried through, which persuaded me to refrain from the exaggerated present max rotor speed hype. Thanks to light [...]

Crash – Vbar wigged out

Here is a PNG file showing a picture of my event log in my Vbar after a terrible 3 second crash while spooling up before lift off.  There were very deep gashes in the dirt where the blades hit and dug in.  While spooling up quickly (a fast spool up rate) and with transmitter sticks [...]

Vbar gov and Castle ESC’s

After speaking with Castle support I lowered the Headspeed Change Rate to Low (value=2) and ~95% of the motor stutter is gone using the Vbar default gain of 25 and throttle curve of 70-60-50-60-70, and minimum throttle % of -70. Originally I was using a custom value of 20 for the Headspeed change rate because [...]
