Default MAW010B2 Helicopter - Why does the motor cut out at half throttle ?

Hello everyone - I'm new to this forum.

Can anyone tell me why the motor of my MAW 010 B2 3 channel helicopter is misbehaving ?

After switching on the receiver first and getting a steady red on the on board LED; then turning on the Transmitter and moving the throttle stick to full, then back to idle, and getting a steady red on the Transmitter; any attempt to spool up and take off results in the motor cutting at about half throttle, at which time the on board LED starts flashing.

I'd be grateful for any advice.
Dave B.

Hi Dave! Welcome!!

Do you have a full charge on your Battery? Have you verified that with a DVM or anything?

Default MAW010B2 - motor cutting out.

Thanks, xuzme 720, for your reply.

My heli has 8 NiMH cells and the battery off load voltage, after charge, is 11.25v, which seems reasonable.

I did wonder if the battery should be a LiPoly; in which case, the low voltage cut-out on the ESC might be the culprit. What do you think ?

Dave.

If the ESC is not set up for a Nimh set-up (ha ha), then yes I'd say it should have a lipo to make it happy. Although, I don't have any experience with this heli. Is it an RTF bird? or did you put in your own ingredients?

One last question, what is the voltage when it shuts down?

Default MAW010B2 - Motor cutting out

I'm trying to sort out this helicopter for a friend. He bought it cheaply at a local superstore. Yes, it was an RTF model - I'm probably wasting time in fiddling with it - but, that's what it's all about !

It's difficult to get at the motor terminals to check on-load voltages because the owner has cemented the cabin moulding onto the airframe after numerous damaging crashes !

I'll let you know the voltage at cut-off when I manage to get there.

I don't know the model, however you stated:
"switching on the receiver first ...then turning on the Transmitter "
is not a good idea in the R/C world. Transmitter (TX) should always be the first one on, and the last one off. This ensure that YOU have control of the model, and not any other signal (or RF noise). Even with 2.4, this is still a good habit. You should also always check that your throttle is at the lowest point, and any flight switches are correct before turning on the model.

would this effect what you are experiancing? perhaps. some ESCs or RXs have safety programs to prevent accidental full throttle starts.

As other says ... Tx first - RX second ....

And if you need to set throttle range ... which is not usually the case with the Supermarket specials ..

Do this only with a 'proper RC ESC equipped model' :

a) First make sure Throttle trim is centred.
b) Switch on TX
c) Move Throttle stick to FULL
d) Switch on Rx / power up model
e) Listen for BEEP
f) Immediately put Throttle stick to idle
g) Wait for series of beeps indicating range set.

I then advise switch of Rx then Tx. Yes - you can go straight to flight - but I prefer to switch all off and then back on again to make sure all is set OK.

Switch on TX ... throttle to idle.
Power up model.

All should be OK now.
