rpm readings with frsky telemetry on gaui nx4 gasser

[leatherface]

hi,i recently converted my nx4 to gaui t10 gas engine.as i have been breaking in engine ive noticed my rpm readings on my transmitter screen jumping all over the place.when at an idle they are around 600-700,but will jump up to 10000 than back down than back up.the ignition system for the gasser can cause interference with electronics,do you think this could be the cause?it is mounted underneath at the back as far from fbl and reciever as possible.thankyou

Hello,

can you let me know what sensor do you use?

Yes, ignition could cause such issues. It is important to place all the electronics as far as possible from high voltage part.

Hi, im using the align rpm sensor. Ignition module is mounted underneath as far away as possible.

Hi,

probably the problem is in magnet orientation or sensor is too far from the magnets.
Make sure magnets are oriented in the same way and the sensor is as close as possible.
