| Winch piggyback control - Cheap, No CH needed / Proportional remote control
Hi all. I have TRX-4 and have been trying to find a way to add winch forever. Sure there are options but I just didn't want to add another fob to tag around or spend more $$$ to replace good existing remote. I was participating local SORRCA event at the horsemens trail CA and witnessed a few people struggling using winch and controlling the truck at the same time. Then it hit me. What if the winch is connected parallel to the main motor? So I made the simple diagram and wired it up. It consists of RC4WD 3S capable winch, 1 momentary DPDT switch and 1 SPST main switch installed somewhere in the truck. Momentary switch will manually run winch in and out. Main switch will put winch parallel to main motor. This is how it would work. When winching is required, pull the line out using momentary switch. Set up the hook. Turn on the main switch - now winch is parallel to the main motor. Drive - Throttle and steer - winch will pull same rate as throttle. When finished, turn off main switch, store winch hook using momentary switch. After the bench test, I find it to be working as expected. However, I am sure there is a lot hole in this concept and more experienced someone can chime in and help making this useful. I will post up some pictures. If I finish installing in the truck, field test might be possible over this weekend. Thanks and let me know if you are interested in this idea |

Interesting idea. Should work ok, but may have some intersting side effects. I wonder about how the drag will react with two different motors? Also, it may get a bit of “clod stall” (search for it) - electricity always takes the path of least resistance, so if the winch is stressed it may stall earlier than normal as the electricity can go to the other motor instead, or vice versa. Not to say it will, as the motors are different size and resistance... have to just try and see. Also, as a fun exercise, remove the battery and turn on the spst switch to connect the winch. Then grab a wheel and give it a good spin.. the winch should turn too |

Clod stall.. Ok so I would need separate ESC for the winch. I do have a backup one but really wanted to keep it simple and at a minimal cost. Thanks for the input. Now I know what to do if one of the motors stalls. Sent from my SM-G930T using Tapatalk |

Yep. Not sure it will be too much of an issue as clod stall appeared even when running two Esc off the one battery, yet people do it all the time with winches. I’d just try it and see | |

Explain to me exactly how you plan on keeping the line taught when the truck moves forward faster the the winch, but the winch will still be required? Solutions for keeping the anchor from coming loose during the above described situation? Solution for keeping the line wound on the spool during the above described situation? Interesting idea. I can tell you that it doesn't work in real life, unless you are using a wheel winch. Good luck, hope you can figure something out. BTW the solution is practice winching, controlling a winch, throttle and steering gets easy with practice. Hell there are guys that drive one handed better then I drive with two. |

I do have problem right now though. All is hooked up and when I move to momentary switch, the steering servo goes nuts.(shv500) it shares the 3s jst connector but not sure how it's effecting steering. Sent from my SM-G930T using Tapatalk | |

If I'm understanding your idea correctly, the thing that bothers me is that you cannot control the winch independently from the wheel motor.

The Bastens winch control module might fit the bill, but it appears to have been discontinued. Bastens Winch Control module works with either 2Ch or 3Ch transmitters |

At this point though I can't get rid of glitches. When I activate the momentary switch steering ramdomly twitches or locks to the right. Tried running separate battery for winch but it would still glitch. Gotta figure out why it's interfering. Sent from my SM-G930T using Tapatalk | |
