MJX F45 not binding


hello there I have just received my MJX F45

I cannot seem to bind the transmitter to the helicopter. I have followed the instruction manual but does not seem to work. I plug the battery into the chopper then turn the transmitter on then I slide the throttle stick to full position then back down then the red light stays solid but the chopper does not respond??

Any ideas what I am doing wrong or is this a dud chopper?

Try this:

1. Make sure the outermost sliders on the tx left and right are fully down
2. Make sure the throttle stick is at the bottom
3. Turn on the tx
4. Plug in the battery and set the heli down level
5. Push the tx throttle stick to max and back to min
6. Move the right stick to check for servo movement

Thanks for your reply. Yes i have done all what you have said with no luck.

The servos do not move only time they slightly move is when the power plug is inserted.

I found if Aileron/Elevator Stick little not center, it will make can't bind. Problem from some Aileron/Elevator spring weak. You should release stick adjust mode of the throttle side and check . If it can easy move to center all direction all time and stable. Then you exchange left and right stick side by turn out 3 screw at the each front side TX. and carefully inner VR plug inside TX change also.

hello

I have the same problem with my mjx F45 ..."The servos do not move only time they slightly move is when the power plug is inserted."
Have you found a solution or do you have any idea what 's going wrong ?

Thanks

Hi there guys.
I have the similar problem with my f45. Only exception is i don't get any reaction from the copter at all.. When i plug the battery in (fully charged) nothing happens, not even the led light. I measured that the power gets from the battery to the pcb but no juice gets to the diode nor to the motor or servos. Could it be faulty electronics?

Edit: Problem solved, it was in fact manufacturing defect - poorly soldered black cable from battery to pcb. Although it is "fixed" in position by hot glue, mine was a little loose so the copter was out of power. Fixed it again and i'm back in bussines. :-)

Any news regarding this?
Did it help with a new CB ?

My copter does have power for the "spotlight" and the servo makes a short move when putting the power plug in. But other then that its dead

Similar issue, except that the servos respond, but it won't take off.

I am having similar issues. The TX seems to connect with the helicopter and I am able to actuate servos, but I have no response on either rotor.

Any ideas????

I have the exact same problem with mine and it's brand new out of the box. I plug batt into helo, servos move a little but other than that, nuthin. Seems that replacing pcb is hit or miss. This looks like a well made helo but the electronics are garbage.
