Trex 250 upgraded but can.t get it flying well

[tonywv12]

uprgaded my trex 250 to beastx and dfc head used longer balls on outer swach to get blue light at 6 degrees seems to be hitting about 7 I have left back ball as standadrd as dont know how to extend it, pots are set as in picture still getting a nodding effect even after adjusting top pot it has impoved it but not 100% rudder is stepping out under throttling up and seems to be flying swirly. My mcpx bl seems to fly a lot better.

my 300x flew like it was on rails. So i must have some thing set wrong. any help hints etc would come in handy.


Thanks
Tony

Not sure if its any help but there was an old thread on the Beastx on a 250

The pot is quite critical, too high & its horrible!

I am using cheep es es08de servos but canot seem to find the frequency they should be using so they are set to 50 so dont know if this will effect it flying properly.

i get nodding below around 85% throttle.

Yes mine is nodding too, have altered top pot wich makes it better when tuning it so far but when turn it more don,t seem to do anything, but then don,t seem to get rid of it

crank the headspeed up and see if it fixes it. im talking flat 95% curve and test
