4200XL hydraulic issues

[Yard Toad]

You mentioned that you replaced the tower pro Servo with a Hitec Servo, did you go into your Tx menu and reverse the function of the Servo. I replace all of my servos to Hitec and they run reverse to the tower pro ones. Also I adjusted my end points to 100% on all of my servo channels. Found out that with the end points set at 120%, I was burning up the tower pro servos. They were over heating because they were bottomed out every time I would open the valve. Reduced the end point and check to see that you have good movement of you cylinders. Hope this helps. Keep us posted.
