Help about the ESC of my new Grasshopper

Hello everyone

I need help with my new plane.
I have bought a L-4 Grasshopper 1400mm EPO (PNF) with all necessary accessories (batteries, charger and TX/RX). I've ridden it and I have binded it to my 4 Channel TX/RX (Hobby King 2.4Ghz 4Ch Tx & Rx V2), but failed to run the engine. All other channels with the exception of the throttle responds. The engine emits a series of beeps and does not respond to command. The box did not include the manual to calibrate it, can someone tell me how I can do it.
This is the technical info of the plane

Motor: 36-48 700kv Brushless Outrunner
ESC: 45A w/BEC
Prop: 12x9
Servo: 9g x 4

try to revers the throtle in the TX channle 3 on futaba's, the esc is looking for it to be right before it will arm.

a Beep every second or so, usually is a prompt for you to do something 8like when it has entered programming mode), or a No signal coming to the ESC from the RX.

Q: when you did reverse the channel on the TX, did the ESC sound the same way ?

Q: Have you tried to Unplug the ESC from the RX, and power it up, how does that sound (if it sounds the same way, you know you got no signal to it)

A non moving motor could also be a Bad connection on one of the 3 wires, with 2 working wires it can still make beeping noises.

Originally posted by Tarkun I have opened the plane and found that the wires connecting the ESC and the engine were wrong. I corrected them but it still sound the same. A beep every second.

What did you find that you think was wrong? And what did you change? If all 3 motor wires were connected to the ESC, it should work (although it might spin the motor in the wrong direction).

Just to confirm: your radio can make all of the control surfaces work? ie your rudder, elevators and ailerons all move in both directions?

I agree with the previous advice - it sounds like the ESC isn't happy with the way something is connected. Here's a few things to check:

1. Is the ESC plugged into the receiver correctly? It needs to be the right way around and pushed in firmly.

2. Do you have a good bind with your radio? Is the red light on the receiver on and not blinking?

3. Is your radio's throttle lever all the way down? Is the throttle trim lever centred? The ESC often doesn't activate until it "sees" zero throttle, to prevent accidental operation of the motor. Perhaps you should try moving the throttle all the way up instead, and see if that makes any change.

4. Check the connection of all the wires from the battery to the ESC to the motor and receiver. Make sure each connection looks like it has a good firm contact or is soldered well.

5. What is your start-up sequence? Make sure you switch on your radio transmitter first, then connect your plane's battery.

6. If possible, try to test the operation of your radio with another model, and test your model with another radio. It could actually be that the throttle channel of your radio is not working, or alternatively your ESC and motor might be faulty.

Hopefully these checks will show up what is wrong. Sorry to hear your first experience with HK is not a great one. Good luck, and let us know if you need more help.

Try hooking it up to one of the other channels (that work with the servos)... But be careful NOT to have a Prop on when you try it.
