View Full Version : Limit problem on Trex 450 w/gy401, ds520, DX7
04-25-2011, 08:25 AM
I have tail slider centered and servo horn set to 90 degrees. Ball is on the 10mm position on the horn. Rudd Travel is set to 85% / 110% Gear set to 72% / 72% limit pot set on gyro is turned all the way down but I still get binding on both ends and servo buss. I have looked on line but there has got to be something I am missing. I don't think the pot should have to be turned all the way down. Any help would be great.

You need to shorten your rubber/tail control rod. Also set RUDD travel at 100% (L/R), and center tail slider. 80-100 is what I shoot for with my 401's limit pot setting. Change RUDD ATV's once you fly to determine if you have a faster turn of rate either left or right.
Hope this helps

Thanks for the info but I am still confused then. If I shorten rubber/tail control rod then would that not affect the center of my tail slider. I have used Finless's videos as marked the rod both ways and found center. I even taken a ruler to make sure it is right. all is centered. The servo is at 90. I will change the RUDD travel when I get home but i think I already tried 100%
