I am pretty sure it is a 4th valve issue and that the valve isn't closing as it should when the others are opened....but getting it lined back up in the correct spot is a challenge. If you move it too far, it closes the valve all the way and the motor shakes and I immediately turned loose of the control. I cant seem to find that sweet spot. Also, I have checked the 3 way switch on the controller and it is all correct. The wheel above the left joystick on the controller seems to have no effect on my model...not sure if it is supposed to.
Hate to be the bearer of bad news but Mobil DTE 24 is actually 32 weight. I know it's misleading as I have also been a victim. Its the 20 series of Mobil DTE.
You have to look at the "ISO VG" (weight/thickness) on their website here: https://www.mobil.com/en/industrial/...s/mobil-dte-22

Also keep in mind, RC4wd recommends to use Mobil DTE 22 which ironically is the ONLY one that matches with ISO VG 22 weight just to complicate things more.
Have you figured out your issue yet?

Wow I just realized the last post was exactly 1 year ago.
