Default JC 120SX stuck at 20%

I have a jetcat 120sx and the throttle stopped working in flight, I thought it was a dead stick but when the plane floated by the turbine was still running at say 20% not enough to fly but a lot of thrust, the throttle would do nothing. I had to land in tall weeds and it did do a lot of damage to my Flash. I have had this turbine in my flash for 400 to 500 flights. I checked all the data and could find nothing out of the norm. Battery voltage was fine pump voltage was normal, the receiver was talking to the ecu , no restrictions in fuel line.Any ideas? Seems to me if I had a fuel pump problem the pump voltage would of been high.

Number of years ago, I had a P-120SE throttle stick at max rpm right after takeoff in my Flash. Could not shut it down or anything and had to wait til it ran out of fuel.

Turned out the comm board in the ECU failed and was replaced. Could be a data cable as well so you might try a different one.

I had a clogged fuel filter from algae and a failing fuel pump that made my old Titan react exactly as you described above. Went to full throttle during a flight and got about 1/4 throttle. Immediately landed.
