I have a Trex 500 with the makido head conversion and a vbar 4.0 setup,

I am using a scorpion 1600kv w/14 t and a castle ice 75. gov mode @2700. Both flew well with the flybar with gov gain a 29% could this be my problem to high of gov gain now that I removed the flybar?

I am having trouble with the gain settings both tail and cyclic, I have no idea where to set the gains, it seems to hover and FF flight fine with the settings at 75 tail gyro and 33 head cyclic. Once I start any kind of 3d it seems to start wobbling both the tail and cyclic, the tail will get so bad that I have to hit auto or I fear it will destroy itself.

Does anyone have a vbar 4.0 set up that works or have any idea where I should set the gain settings.

Cheers, Mark M,

My bet is that the sensor is mounted on the tail boom holder and that vibration from the gears inside the tail boom holder is overwhelming the sensor. Here is my earlier post on the subject: https://rc.runryder.com/helicopter/t603768p1/ I'm using 5.0 software now but looking at the old setups that I have saved from 4.0 I was using a main rotor agility of 40 and gyro gain of 40. For the tail rotor was using a gyro gain of 80.

Ok i think I may figured it out, I think that after going over mechanical setup and electronic setup with the vbar, I am concluding that it is my castle Ice 75 gov mod settings,

I set the esc to 100% and use will throttle and a 13T pinion to gear it down, I am going to try to it and see if I still have problems.
