Andrew Calcutt Posted March 24, 2022 Share Posted March 24, 2022 These are for use with a separate receiver battery,called opto I think.They should still work and sometimes it's not a bad idea to use a battery instead of BEC. Quote Link to comment Share on other sites More sharing options...

EarlyBird Posted March 24, 2022 Share Posted March 24, 2022 An ESC with no speed control? I don't understand. Steve Quote Link to comment Share on other sites More sharing options...

MattyB Posted March 24, 2022 Share Posted March 24, 2022 40 minutes ago, EarlyBird said: An ESC with no speed control? I don't understand. Steve As per the AliExpress listing - certainly unusual... RW.RC Self-starting Brushless ESC 10A / 30A / 60A / 80A / 125A / 200A with Driver Board No PWM For RC Fan Pump RC Plane This unique ESC, technically speaking, should not be called an electronic speed governor. It has no signal line, so it cannot adjust the speed of the motor. As long as the battery is plugged in, the motor will start at full speed immediately. This brushless controller can be applied to some equipment that does not require speed adjustment. It can be widely used in various fans, electric skateboards, underwater propellers, oil pumps, computer cooling, electric drills and various aircraft models.

Fulvio Posted August 3, 2023 Share Posted August 3, 2023 Good Morning to all Team My name is Fulvio from Italy and i would like to summarize all your comments on the topic. I have 2 Brushed motors assembled on a Boat model (Torpedo Dachs Graupner). If i understood well is not possible to use 1 ESC and connect 2 motors but is better 2 motors and 2 ESC, one for each single motor. Ok this is ok for me. Now the topic that i need to finalize with you is the follow Can i utilize an "Y" cable to joint the 2 ESC and connect both of them in this case to channel 1 of the RX? If i understood well yes i can but on one of the ESC cable before to joint on the "Y" i need to remove the central wire. Correct? This is the clarification that i need. Thanks for your support on the topic. Best Regards Fulvio Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted August 3, 2023 Share Posted August 3, 2023 Correct - assuming your ESCs incorporate BECs this allows one of them to provide power to the receiver without the ESCs interfering with each other. Quote Link to comment Share on other sites More sharing options...
Tom Gaskin 1 Posted August 3, 2023 Share Posted August 3, 2023 Fulvio, As you say that you are using brushed motors (only two wires to each motor) you can use one, large speed controller with,depending on the battery size and motor operating voltage, the two motors connected in either series or parallel. This current discussion is about brushless motors (those with three connections to each motor), where separate esc's for each motor is required.

PatMc Posted August 3, 2023 Share Posted August 3, 2023 (edited) @FulvioI think @Martin Harris - Moderator has misread the type of motor. 2 brushed motors would only require a single ESC so long as that ESC is rated for the combined current of both motors. Tom posted as I typed. Edited August 3, 2023 by PatMc Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted August 3, 2023 Share Posted August 3, 2023 That's a bonny boat - looks fast even standing still. Do twin-engined boats ever use differential throttle to augment the rudder for steering? If so, could that be a case for using two brushed controllers, with some mix to rudder in the transmitter?

Martin Harris - Moderator Posted August 3, 2023 Share Posted August 3, 2023 Yes Pat - I failed to spot that! No timing issues with brushed motors! Quote Link to comment Share on other sites More sharing options...
