Help with receiver/channels

Lynxmotion Electronics & Software

I recently got a fingertech viper robot and, although it was very easy to assemble, controls are a bit different for me (I’m still rather a beginner in the hobby). The instructions said to plug the ESCs into receiver channels 1 and 2. When I did, pushing the control stick straight forward does nothing, however, if I push to the uppermost right position, the bot moves forward. Basically, the controls are off 45 degrees. I’d read that on another forum that you were basically trying to control two channels at once, but I have no clue on how to do any adjustments. I’m using a Flysky SK i6x transmitter and an FS ia6b receiver, just in case those help. Any and all help is greatly appreciated, and thanks in advance.

Hi,

Make sure this is not a configuration error on your Transmitter.

Please, verify the following:
ViperTech

Also, you may try the reset calibration procedure:
Reset to Defaults
V2.5, V2.6 - To revert to default calibration, do the below steps without moving the transmitter stick at all.
V2.4 - To revert to default calibration, do the below steps with the tinyESC unplugged from the receiver.

V2.6 Calibration - The tinyESC comes pre-calibrated with defaults that match the 1000-1500-2000µs of most radios, but if you wish to change the limits or center position:

  1. Plug tinyESC into the radio receiver.
  2. Power up the tinyESC.
  3. Briefly short the two tinyESC Calibrate pads with anything metal. After removing the short, the Red and Green LEDs will alternate flashing indicating calibration. (see image)
  4. Move transmitter stick to high and low limits.
  5. Return transmitter stick to center.
  6. Briefly short the two tinyESC Calibrate pads again to save the settings and exit the Calibration routine.
    A successful calibration will flash the Green LED three times. If the Red LED flashes three times instead, the defaults have been restored.
    The center position is now “motor off” with full forward and full reverse speeds at the upper and lower limits.
    *You may calibrate multiple tinyESCs at once (as in channel mixing).

V2.5 Calibration - The tinyESC comes pre-calibrated with defaults that match the 1000-1500-2000µs of most radios, but if you wish to change the limits or center position:

  1. Plug tinyESC into the radio receiver.
  2. Power up the tinyESC.
  3. Briefly short the two tinyESC Calibrate pads with anything metal. After removing the short, the Red LED will turn on solid indicating calibration. (see image)
  4. Move transmitter stick to high and low limits.
  5. Return transmitter stick to center.
  6. Briefly short the two tinyESC Calibrate pads again to save the settings and exit the Calibration routine.
    The center position is now “motor off” with full forward and full reverse speeds at the upper and lower limits.
    *You may calibrate multiple tinyESCs at once (as in channel mixing).

V2.4 Calibration - The tinyESC comes pre-calibrated with defaults that match the 1000-1500-2000µs of most radios, but if you wish to change the limits or center position:

  1. Plug tinyESC into unpowered radio receiver.
  2. Jumper the two tinyESC Calibrate pins with any piece of wire. (see image)
  3. Power up tinyESC. The green LED will go solid. If not solid, cycle power.
  4. Move transmitter stick to high and low limits.
  5. Return transmitter stick to center.
  6. Remove the jumper.
    The center position is now “motor off” with full forward and full reverse speeds at the upper and lower limits.
    *You may calibrate multiple tinyESCs at once (as in channel mixing).

See this part here:
Note for Spektrum users: The Spektrum transmitters do an odd thing with their mixing. If your motors only run full speed when the stick is in a corner (meaning going straight ahead/reverse is not full speed), then you will want to calibrate the tinyESC just like the directions above, but make sure you only move the stick straight up and straight down, not moving the stick sideways at all. This will give you full speed for forward and reverse!

I ended up having to get a new esc which cam in yesterday. Hence the reason I haven’t been able to try some of the fixes. Instead of trying to describe what the bot does (it behaves basically the same now as before the esc went out), I’ve linked a short video. I’m leary about flashing the esc’s since that’s something I’ve never done before nor saw what an esc looks like when one needs adjusting. I’ve added a mix channel that mixes channel 1 & 2 at the same rate, and have enabled elevon. If you need to see the exact settings, I can take a pic. Thanks so much in advance.
