RC Motor and ESC Wiring - Part 2

[@mtbcyclist]

Nice video. I am getting into scratch build and RC planes and a total newb, but did RC cars hardcore 20+ years ago. This video fills in the gaps and answers my questions. Thanks!

[@chiragshelar8564]

I study in class 8.i made a biplane . This 3 part video helped me a lot for my science project . This helped me a lot thxxxxx xery much.this were greatest videos I had ever seen foe esc.than you.

[@a10nmw]

Very informative video. Many thanks

[@rueda82nd]

Great videos , lots of info for us newbees Thanks

One additional note is the early ESC had a opto sensor to synchronize the motor spin direction to the ESC control circuit.These were called "sensored" ESC units. Most today don't use this (some car ESC are still sold as sensored types). The sensoreless ones shown utilize the EMF filed that is generated by the motor windings and magnets, this signal gets processed and then used as a basic sync method to know where the motor shaft is during acceleration. This is the not the best way to do it, sometimes sensorless motors get what is called "cogging" due to the EMF signal not syncing up well.

@eastcoast78 - Nice job on the Eurofighter! Looks great. Thanks for subscribing.

Hi, thanks for the feedback! We do have several new video series in the making including everything LiPo, telemetry systems, etc. Rob has a long list of construction videos he's working on as well. Servos are a real challenge since each manufacturer has their own size naming, but we'll see if there's something we can do in that area. It's definitely a challenge. We use Gold Dealer mats with a nice chart from Hitec, Futaba has a spreadsheet, etc. No good cross-references though.

I ought you a beer. Very nice educative video. Thanks

[@2BrothersHobby]

@eastcoast78 - Thanks a lot Canada! As far as the ESC RX lead, the ESC radio lead plugs directly into the receiver. The smaller leads you see from the ESC connector in the video are going to the battery monitor made by Electrotek RC products. Its "siphons" full power directly from the battery and alerts you when you reach voltage cutoff threshold. It's not necessary at all, just something we like to use, especially on helicopter setups.

[@2BrothersHobby]

Tower Hobbies is selling Tactic TTX404's for 69.95 right now. We've used them before and they're a solid 2.4GHz radio system. Very basic, but solid.

[@2BrothersHobby]

@petritwow - The cost varies tremendously depending on your application. Starting under 100.00 USD for all three (micros) to several hundred as you get larger and more powerful in size. The receivers average 35.00 - 75.00 but can go over 100.00 depending on how many channels you require.

[@2BrothersHobby]

@aannoonniimmss - Yep, try reversing the throttle channel (channel 3) on the radio transmitter. Futaba radios typically need the throttle channel reversed to work with Electronic Speed Controls.

I just set up my bixler 1.1 with a TX RX: Turnigy 9x TX/RX Battery: 2.65 amp 3 cell ESC:Hobbyking 20 amp Motor: 2620-1900kv Brushless Outrunner

[@eastcoast78]

now your ESC/RX lead is on the Batt prongs? great vid BTW.very informative for someone jsut getting into Electric planes etc... Cheers Canada

[@aannoonniimmss]

@2BrothersHobby Thanks, that helped :)

[@eastcoast78]

@2BrothersHobby thanks,jsut getting her ready for a maiden,.have COG probs though Are you on RCGroups?

[@jonjvilla8672]

hi, do you guys happen to have a video where show how to connect 2 or more batteries to one BEC? or where can I find a video which shows that. Thank you!!

[@airgunningyup]

question, how do you know the voltage of any given esc?? in other words, an esc says 40 amp prgrammable , but doesnt say required input volts?

[@kurtisjeter1174]

I got a motor and ESC with no plugs. How do I go about selecting the right/ best plugs to install the esc on to the motor ?

[@lampini]

if your esc does not come with color coated wires(I.E all three are black) how do you know how t hook it up correctly?

[@ahdennis]

@2brothershobby hey can you recommend a cheap ( as in like less than $70) but good transmitter for this sorta stuff?

[@thomassforza8990]

Hey guys new with RC airplane, do not understand how the motor is fed from the speed controller. I know the three wires go to the motor and two to the battery, and one plug to the receiver. But how is that set up controlling the motor speed? Tom

[@richardthomas1080]

I have had several multi engine electric aircraft and have never run into this problem. I hope you can help. I have two 46 size motors hooked to two 80 amp esc's. I am using a separate on board power supply so I have disabled the BEC on each controller. The battery leads from each speed controller meet at the center of the wing and have been combined into one lead. I am also using a safety arming plug. I am using two 5 cell batteries with a parallel plug. The problem occurs when I power up both motors together. When you advance the throttle all is well for the first quarter but as it is advanced the motors begin to oscillate and if I let it continue they will even begin to cut out alternately. But when I disconnect one esc the remaining motor operates perfectly. I have performed this with both motors and by themselves there is no problem. Any help would be much appreciated.

[@athannaelanderson3806]

You ever come to a solution?

[@allthenames1986]

my esc is not recognizing that I am at full throttle. In mode 2 I've tried setting my RX all the way down then turning on my RX then plugging in my battery. I then here the initial musical tone then three short beeps. Then short beeps every 15 seconds or so. I've also tried setting my throttle all the way up before powering on and get the same result. I've tried setting my trim to 0, -100, -120 and 2...same result.

[@aannoonniimmss]

Hi, nice video here. I'm beginner in a RC world. I've a Futaba T6EX transmitter, Futaba R617FS receiver, Arrowind 18A ESC, Ripmax Xtra brushless motor 2829-16, a Li-po 2 cell 7,4/1300Ah battery and some servos, but when i put everything together, the motor doesn't work, just makes beep sound. Servos work fine. Any idea what I do wrong? do I need to change any of the components? Thanks.

[@andrewv.2225]

I recently found this Rc Fuel helicopter dumpster diving and I like to know if its worth spending the money to repair it or if im better off selling it as a parts thing.I would appreciate it if I would get back a reply soon if possible or if someone may guide me thru on wiring or connecting it back together.

[@collinstiers5883]

ok, so I was looking into this, and i have never built anything RC in my life, i am just a kid so my budget is pretty low, are there anyother cheaper RC trasmitters and recivers out there, and also do the reciver and transmitter have to be the same brand??

[@sarangjoshi8252]

How can I connect TWO brushless motor to the receiver....??

[@chiragshelar8564]

Hey just bring two same type of motors. Combine there wires (i.e connect the same colour of wires).and just plug the connected wires into the esc

[@petritwow]

How much does the esc the reciever and the motor cost?

[@2276buggy]

Can you use NIMH or Lipos? Does it matter?

[@2BrothersHobby]

@eastcoast78 - 2 Brothers does have an account on RCGroups. We are username 2bfly.com

[@eastcoast78]

@2BrothersHobby cool that seems like a cool add on. haha it was late last ngiht when i watched the vid,and what i thoguht was the ESC lead was in oyur Batt port,but i jsut watched it again and noticed its was in the Throttle port lol my bad. BTW ive Subscribed ... Check my vids out.;0)
