I have seen the need to reassemble some instructions for setting the EPA, aka End Point Adjustments.
there are 3 different radios that are most common for the Ascenders, mainly the RTR version of the DX2E

On the radio, make sure the knob (AVC) in the front of the radio is turned fully clockwise. Now make sure the steering trim is centered and retest the steering L & R thow with the truck upside down so you can see how far it's steering. If you are still having trouble getting max steering to left and right you will need to reset your "steering end points"

End point adjustment is vaguely touched on in the radio manuals.

Here are links to the manuals.
DX2E - RTR - Manual (spm2330)
DX2E v.3 - Manual(spm2322)
DX2E Active Telemetry - Manual(spm2335)

How to access EPA mode

Seems the DX2E - RTR, the new DX2E Active and the and the D2XE v3 are different to access the EPA mode !

RTR radio and DX2E Active radio
Hold the trigger in full reverse and the steering wheel to the right while switching radio on, green light starts flashing.
Release trigger, the radio is now in EPA mode.

DX2E v3
Hold the trigger in full reverse while switching radio on, green light starts flashing.
Release trigger, the radio is now in EPA mode.

Here is how i do it -

Radio switched off, steering dual rate knob turned all the way up. Throttle and steering trims turned fully counter clockwise.

Power up truck and set it on the ground upside down, make sure its not going go anywhere, cause the radio is off!

RTR radio and the new DX2E Active radio
Hold the trigger in full reverse and the steering wheel to the right while switching radio on, green light starts flashing.
Release trigger, the radio is now in EPA mode.

DX2E v3
Hold the trigger in full reverse while switching radio on, green light starts flashing.
Release trigger, the radio is now in EPA mode.

Throttle and steering trims are now EPA adjustment knobs to be used in next few steps. Wheels on truck probably running cause the throttle trim is turned, thats why its upside down "thumbsup"

Turn down the throttle trim knob then hold throttle trigger at full forward speed, while holding down trigger turn throttle trim knob to set your desired maximum forward speed, then release throttle trigger. ( ignore what the wheels on your truck are doing after you release trigger because the throttle trim knob is turned up) forward EPA is now set. Wait a second or two for radio to record new setting.

Turn down the throttle trim knob then hold full reverse speed and adjust throttle trim knob again to set desired reverse max. speed. Release trigger and reverse EPA is now set. Wait two seconds again.

Turn throttle trim knob to the middle to stop wheels turning on upside down truck.

Turn down the steering trim knob then turn and hold steering control fully to the right, while holding adjust steering trim knob to set maximum desired steering angle, release steering control to center, right steering EPA is now set. Wait two seconds.

Turn down the steering trim knob then turn and hold steering to the left, adjust steering trim knob to desired maximum left steering angle then release steering control to center, left EPA is now set. Wait two seconds.

Now center the trim knobs and switch off the truck and radio, job done.

Now you can enjoy the full throttle and full steering angle available on the Ascenders, mine was set at a slightly reduced angle out of the box.

*** When I set steering EPA, I usually turn it till I hear the servo start to make a little noise and the knuckle is bottomed out on the c-hub. I then back it off so I have a 1mm gap between the knuckle and c-hub.
Considering I run a 500 oz/in Savox 1230sg that will bend and break parts quickly, I leave a small gap between the knuckle and c-hub.

**Not sure if necessary but I have heard where some people may have to rebind the radio and receiver afterwards, if so here is how to rebind the transmitter and receiver.

1. With the receiver off, insert the bind plug into the BIND port on the receiver.
2. Power the receiver through any other port. The green LED will flash continuously, indicating the receiver is in bind mode.
3. With the steering wheel and throttle trigger in the desired preset failsafe positions (see the Failsafe section on this page for more information), press and hold the bind button and turn on the transmitter. The green LED on the front of the transmitter will flash within three seconds, indicating the transmitter is in bind mode. Release the bind button when the green LED flashes. Continue to hold the failsafe positions until the binding process is complete.

Failsafe is no throttle and no steer should you loose communications between the two, in the event that happens the vehicle just stops.

Do not touch the steering wheel or the throttle during the bind process.



I hope this can help some of you out.
