after setup is done on the 3g

so after you finish the setup process with sub trim and swash amount. Before flying do you set them back to zero on the radio before starting the controller.

NO, you must let the subtrim as is when done, also don't use 3.0 the tail wont hold, use 2.1
Here's some instructions I did up, not much support for 3G anymore.
Ok 3G is a bit different than the 3GX.
Sensor must be mounted level or you'll get drift. Sometimes you need the GP780 mounting, pad, steel plate and then pad and even a strap at times.
When you setup your cyclic in dirsetup you actully get all the cyclic at 80% stick out of setup.
For a 420 - 500 maden settings. In dirsetup set collective 12- 13 and cyclic 13
In the TX drop the cyclic DRs to 85% after you run dirsetup and expo at 30. At 85% you'll still see full cyclic before max stick. After maden raising the DRs simply makes the cyclic react faster and no need to rerun setup.
If you max the DRs and still want faster cyclic rerun setup and go to 13.5.
The max cyclic and the flip and roll rates work together. Control rates determine how fast the cyclic reacts and the max cyclic how tight the flips and roll are.
Set cyclic expo in the software to 0 and use expo in the TX.
The swash return speed needs raised 5 points right away, it returns to fast after input.
For rudder lower rudder lock 5 right away, if you get wag with low gain lower a bit more and if you get a bounch on hard stops after getting the gain set bump up the stop lock, usually 3-5 is all you need.
Gain pots 12:30 for elev and just a tad higher for aileron. If you get elev bobble slow FF lower to 12:00.
After all setup, link up, place throttle at mid stick and you should get all 0's displayed for command rates in the command display screen. If don't get all 0's rerun setup till you do. The 3G is real sensitive to the cyclic center position and will drift or want to tip if you don't see all 0's.
Set TC like 0 60 80 ** **- 0 60 85 ** ** etc and make the IU mid stick the same as normal.
Set PC normal 0 40 45 50 75 100 so you have enough head speed for the 3G to work before it gets light
If you get a slight drift you can use a small amount of trim, one or two clicks with the 3G, but if you do rerun setup and check the mechanics and tweek the subtrim if you can't find the cause.

thank you got this on a used 250 from here but could not get it in the air yet.

Welcome, Lots used to dial the heli back by lowering the swash AFR after setup to tune the cyclic but if you go back and over the initial swash numbers from setup the 3G wont work right. That's why ya start with lots of pitch and dial back with DRs and if you end up needing more rerun setup and add.
