Order Number: UT-734287
Product Name: Fms Ranger Trainer 850mm Rtf
Brand: FMS
I ordered an FMS Ranger 850mm. It is a ‘Ready to Fly’ package but the elevators, rudder and ailerons are not working. Only the throttle responds to the controller.
In the ‘Trouble Shooting’ part of the instructions, it says that for any control surfaces that do not move, there could be wiring, linkage or service damage.
Since this is a ‘Ready to Fly’ kit where everything should come working, please may you look into/advise on how to arrange a replacement?
Assembled the kit to the letter of the instructions. When not working, tried various combinations of turning off and on again before dissembling and rebuilding. Fault persists
Thank you for the detailed description and video, this does help us with trouble shooting.
I think it might still be trying to calibrate the gyro which control the surfaces.
Reflex gyro still in its 30 s start-up routine – until the gyro finishes calibrating, the elevator, aileron and rudder channels stay locked. You’ll see the LED on the gyro flashing rapidly; once it goes solid the surfaces should respond. Leaving the model absolutely still and level for 25-30 seconds after plugging in the flight-battery normally clears this.
This is a thread from a customer who experienced a similar issue, I think this might be the problem:
Please let me know if that sorts out the issue? If not I will contact the manufacturer and ask for further assistance.
That is frustrating. I’m sorry to hear you struggling like this. I have forwarded our supplier your details and description about his issue and have asked for their assistance.
As soon as I hear back from them I will come back to you.
I do apologies for the delay here.
If there is anything else I can help with please do let me know.
