as i done a range check first. when i got to the plane the rudder elevators ect ect and motor was working fine, im a bit scared to take the plane up again in case it happens again. do you think i have a dodgy esc?. thanks.
@philipriding - Need more info than the motor RPM. The maximum wattage or amperage in the motor specs will indicate how many amps the ESC needs to be. Additionally, you could be running with the wrong prop, causing more draw than what the ESC is rated for. Sounds like you hit thermal limits on the ESC, it went into protection, then came back on after it cooled down a bit. Finally, most setups are only rated for a few seconds (8-10 MAX) full throttle runs, then back off a bit.
I was flying my rc plane with a 2070 rpm brushless motor and a 30amp esc, after 5 minutes of flight i landed it to see if all was ok. the motor was nice and cool but the esc was hot, even though the plane had a good draft of wind passing through the plane. i took off again and tried the plane on full throttle, when i got to around 200ft the motor cut off and i also lost all control of the plane. it crashed. but lucky enough all i broke was the prop, the range on the transmitter is all ok.
I am looking into buying a brushless motor for my Exceed Champion, and the only information on current is the max efficiency current, which is 48a. what should the amps rating on the ESC be?
@thediamondz1 - The ESC rating is based on the motors peak or maximum amperage draw, not the battery. The battery can only supply what the motor is able to draw, so the ESC never passes more current than the motor's maximum rating, unless you're running the wrong prop.
Jonas, You factor the motor's peak wattage and convert to amps. Watts = Amps X Volts. You then choose an ESC that can handle the max amperage or slightly more to be safe. We have several tools on our website that helps with these calculations. Good Luck!
@MrAlexandros99 - The batteries used on this clinic are from Flight Power, distributed by Great Planes here in the US. The ESC is a Castle Creations Thunderbird. This is their value line of ESCs. Very reliable but also very affordable.
@mayantribe - The BEC power is supplied through the single radio connection coming from your ESC (assuming your ESC has an integrated BEC). There are no additional wires for your BEC circuit. Just plug your ESC into your radio receiver with no motor connected and plug your flight battery into your ESC. If the receiver comes on, your ESC has an integrated BEC. If it doesn't, your ESC does NOT have an integrated BEC (or your reveiver connection is reversed, always check polarity).
If you're still making these beginner "how to"s, consider doing a video about motor selection. I have a small park flyer I bought as a RTF, and I'd like to upgrade to a brushless motor etc. but I'm confused by all the different ways to mount the motors, and which way they face, and those little prop adaptors, and pusher vs pullers, and outboard vs. inboard... I just don't get it.
@gizmoguyar - Great suggestion! I think we'll do just that. There are some tools (calculators) on our website that help with motor selection from a specification perspective, but mounting is another issue. Thanks for the feedback...
How to operate a motor brushless with the ESC but without using a recector and transmitter, what kind of signal is needed at the orange cable? Can I put a potentiometer to the positive and the orange cable to simulate the accelerator?
@chancho00 - There are some circuit designs you can find on the web regarding homemade servo controllers. Try doing a Google search for "homemade servo controller" and you should get some returns. Keep in mind, an ESC is going to be less forgiving than a servo when it comes to end points and input.
does any of this info apply to rc boats as well? I recently got an older model great planes wildcat ss off craigslist, but the radio system isnt working. I want to upgrade to 2.4ghz, but the problem is the boat currently has a mechanical speed control...i'm thinking i should upgrade to an electronic, but i'm not sure about compatibility with the TX, RX, Servos, and the ESC...i dont want to plug something into something else and blow it!!
@moron32 - Yep, the same components are used in boats with lipos and brushless speed controls. In fact, even NiMh and brushed ESCs wire the same way. Connections are all the same with the exception of brushed motors only have two wires to the motor.
@2BrothersHobby Wow! Nice site! Actually....let me do some reading on your site, i'll bet my answeres are already in there lol...i'm surprised I've never seen this one before!
My servo's operating voltage is 3-7.2v. So if i connect my 11.v lipo to receiver..servos get ~11v. I am a confuse. I need another battery for receiver and servos ?
@TheSliekaStyle - You don't connect your 11.1V lipo to the receiver. You connect it to the ESC. The ESC radio connection back-feeds the correct voltage to the receiver. This is the purpose for having a BEC (battery eliminator circuit) built in to the ESC. It handles the regulation of the incoming voltage down to 4.8 - 6.0 volts for your radio system.
@SunTrapped - If you are asking if you can connect a brushless motor directly to a power source, no. The Electronic Speed Controller (ESC) function is relatively complex and involves current inversion, multi-phase signaling, timing, and current management (to name a few). You have to utilize an ESC in order to spool up your Electric Ducted Fan (EDF) powerplant. Brushless RC motors should never be connected directly to a power source.
@collierman57 - Yes, that is correct. Any 2 wires will change the phase sequence and, as a result, change the direction. The outermost wires are often the same color as the ESC leads on medium and larger BLDC motors, so keeping track of just two colors that match is a little easier. I always match the colors to start, and then test the direction. If I have to disconnect the wires during the build, it's easy to remember the pattern of the two outermost wires!
@Mena142 - Glad it was helpful! We'll be posting several more, including multi-engine, external BEC wiring, and navigational lighting. Check back often or visit our website at 2bfly.com under the workshop section. There are flight calculators and electrical reference information there as well. Let us know if there's something specific you'd like to see....
Thank you Very well done. Brian

Since my battery puts out 66amps do i have to get a esc with an amp rating higher than 66amps.

I think you'll find that you can swap any two wires to change the phase rotation and reverse the motor direction.
