Hi
Welcome aboard
Im pleased to meet you
It doesnt make a difference stock TX or BNF TX you should have a good heading hold lock
Heres my MSR with the stock TX
Do enjoy
No twitchiness in mine
I always place the heli on a stable flat surface then plug in the battery pack and dont move her until the gyro has a chance to kick in
Hope this is of help
Take care
Yours Hank
