One way bearing problems

[joe1l]

I decided to build my own x425 using the 425xf frame instead so i could use my BLS451's. I had always regretted getting rid of my original plastic 425 and I never liked the idea of using mini servos on FBL helis especially on direct link like the x4 or any other 425 size heli. i had initially tried converting one of my X5's to use 425mm blades but it was a little too top heavy. it just didn't feel as balanced. With the extra weight, the higher head speed killed flight time and pulled alot more current than it should... 475mm worked excellent though.. i think 450mm + would of worked perfectly but it was too rare a size.

Anyhow the 425xf frame works beautifully and i even have the longer tt boom setup that works with 475mm blades. im using the x4 fbl head with a 3026-1400 motor and yge100lv.

The heli has been flying great except for the OWB which slips under high load. I tried to use the vbar gov and it cannot even handle a pitch pump.

i would of thought that the OWB issues would be gone now.. i am on my 2nd owb 20t... and am not sure what to do next. any suggestions?
