Krill89 Posted March 27 Share Posted March 27 Hi, my first try with electric RC, I have a FlySky FS16 and recently bought a kit of motor, esc,servos etc admittedly cheap, the servos work but the motor just twitches and bleeps, the transmitter has no effect on it, I’ve charged the battery and checked the connections Any help would be great fully received Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted March 27 Share Posted March 27 Perhaps post a picture of your setup so that we can see what is plugged in to where. I assume you’ve connected the ESC lead to the throttle channel? I can’t say for certain but I think this transmitter complies with the normal direction - Futaba kit needs the throttle channel reversing before starting the process. You may need to train the ESC to the throttle channel - most require you to connect the battery with the throttle wide open, wait for the beeping sequence to stop/change, NO PROPELLER FITTED PLEASE, and then close it. The beeping stops/changes once it’s complete. Best to go with the ESC instruction leaflet which will hopefully have been supplied. Quote Link to comment Share on other sites More sharing options...
Geoff S Posted March 27 Share Posted March 27 Also, make sure you connect the BEC lead (the one from the esc to the receiver with a servo-type connector) to the throttle channel or the motor certainly won't run. Quote Link to comment Share on other sites More sharing options...

Krill89 Posted March 27 Author Share Posted March 27 Hi, thanks for the reply. I tried as you suggested but no luck, the led on the receiver is on constant, Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted March 27 Share Posted March 27 I think you have the lead in a socket marked VCC? This is not the throttle channel. Funnily enough, someone else new to electric power made this mistake very recently. Unlike an IC setup, the ESC needs to power the receiver through the channel that supplies the throttle channel position data. I believe this is channel 3 on this radio. 2 Quote Link to comment Share on other sites More sharing options...
Krill89 Posted March 27 Author Share Posted March 27 Fantastic, thank you, all works now, sorry for bothering you with such a simple problem 1 Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted March 27 Share Posted March 27 As a wise man once observed, there are no stupid questions, only stupid answers! It's an easy mistake to make if you are used to connecting the battery to a dedicated slot - although as you probably know, it's only for convenience as the power rails are commoned in the receiver. 1 Quote Link to comment Share on other sites More sharing options...

I hate to mention it, but I said the same in post 3, above - also because of the problem someone had a week or so ago 😛 It wouldn't have crossed my mind either, otherwise. Of course, I would never, ever, dream of blowing my own trumpet. Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted March 27 Share Posted March 27 To be fair to Peter, I did raise the possibility in the first paragraph of my first reply! 😝 Quote Link to comment Share on other sites More sharing options...
kc Posted March 28 Share Posted March 28 It just shows the depth of knowledge available on this forum - multiple members knew the answer! Worth pointing out to a new to electric person that if the motor does not go round the correct way then just swop any two of the motor leads.

Worth pointing out to a new to electric person that if the motor does not go round the correct way then just swop any two of the motor leads. kc - just to clarify for newbies, this is any 2 of the 3 leads going to the motor. These leads carry the 3 phase AC power that the ESC supplies to the motor having converted from the DC input from the battery pack. As written, there is just the chance someone would swap the leads into the ESC from the battery - which is terminal for most ESCs of course. I always take the view that if there is some ambiguity there's a chance of an error being made. Quote Link to comment Share on other sites More sharing options...
kc Posted March 28 Share Posted March 28 I did state "motor leads" ....... but Peter is right to clarify anything that could be confusing and damamging. Quote Link to comment Share on other sites More sharing options...
