AWM Posted February 28, 2010 Share Posted February 28, 2010 This may seem like basic.. basic stuff. But I have the 2 motors mounted in the wings of my plane. I have 2 ESC's. I sort of know how it all goes together. The motors connect to each of the ESC's. The ESC's are joined and connected the to the Lipo. red / red and black / black. Then the Rx plugs on the ESC's go into a 'Y' lead and into the receiver. The Rx plugs on the ESC's are Futaba type. As there are 2 ESC's, am I right in thinking I remove the red wire from one of the plugs? That is question one. Q2... What is the best way to connect it all together? The motors and esc's have 4 or 5 mm of wire coated in solder at the ends, but no connectors. There are however small brass connectors with the motors and esc's, btut they don't appear to be much good. Should I simply solder the ends together and use insulating tape to seal the connections? Can I use connector blocks, the plastic ones with brass screws in them, used in mains electricity mostly. Or something else? Q3.. If I need to extend the wires, what kind of wire should I use? I will need to lengthen the wires from the ESC's to connect to the lipo. And finally, can I get what I need in Maplins.. as opposed to going to a model shop? Thanks in advance once again... I am sure sooner rather than later I will be able to contribute something rather than taking! lol. Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted February 28, 2010 Share Posted February 28, 2010 hello AWM---i would look up some of the threads on the forum here that relate to 'getting started with electric's'.....and take it from there..this will answer your q's..... ken anderson........

Tim Mackey Posted February 28, 2010 Share Posted February 28, 2010 Q1 yes - so that power from only one ESC is feeding the radio gear ( unless of course you are using a separate battery in which case disconnect both redwires )Q2 Depends on your soldering equipment and skill level. The brass connectors are probably actually gold plated and are the best bet - dont use a choc blok type connector unless its a very small model and low power setup.Q3 Best to keep these wires as short as possible TBH - and only use a nice silicon covered flexible multistrand cable of at least the same gauge as the original.Q5 Unlikely to get the connectors - not sure about the cable - I normally use maplins only as last resort for that type of stuff due to pricing etc. Zillions of online suppliers for all you need - including specialists like Puffin models.Edited By Timbo - Administrator on 28/02/2010 13:36:48 Quote Link to comment Share on other sites More sharing options...
AWM Posted February 28, 2010 Author Share Posted February 28, 2010 Once again Timbo - Thankyou! You suggested previously that I use a separate Rx battery. So, that is what I have done. I have the Lipo for the power train and a normal Rx battery in the battery port of the receiver. So, when I connect the receiver plugs from the ESC's into a Y lead I can terminate the red wire in the Y lead, so that there is no red at all going to the receiver.

Tim Mackey Posted February 28, 2010 Share Posted February 28, 2010 Yes...you MUST disconnect both red wires of the leads from the ESCs to Rx otherwise you will be connecting the ESC BEC output voltage across the separate battery you have elected to use. Of course, if the ESC are opto isolated style units then this is un-necessary - many opto ESCs still have the red wire although its not actually connected to anything.
