Fat Freddy Posted May 21, 2020 Share Posted May 21, 2020 Hi folks, Hopefully you can help fill in some gaps in my radio gear knowledge. I bought a super cheap (£26) Himoto 3 channel transmitter/receiver from my local model shop. You get what you pay for and this thing is really cheap and plasticky but basically works. Obviously I use the first two channels for throttle and steering. The third channel has a switch marked CH3 AUX. I fitted lights to my car and plugged them into the CH3 slot on the reciever. In my ignorance I thought that I'd be able to switch the lights on and off using the aux switch but when I tried, nothing happened. I was convinced it was a faulty switch and contacted the shop but as they are closed due to lockdown, it was weeks before they responded. All they said was, the lights couldn't be turned on/off via the aux switch. I replied, asking what it was for then but they still haven't responded. To be fair to them, they have always been a great source of knowledge and advice and if they were open, I wouldn't be asking you lot. So, what do you reckon folks? Faulty switch and bad information? Or is it just my lack of actual knowledge? How best to proceed if I want to remotely turn the lights on and off? (Short of just throwing the thing away and getting a decent one instead) Thanks in advance for your help. Quote Link to comment Share on other sites More sharing options...
CarlC Posted May 21, 2020 Share Posted May 21, 2020 (edited) Are you using a light controller? It would be a small board that the lights plug into and then plugs into the receiver to act as a switch. You can get them pretty cheap on ebay and the most basic would be something like this, although there are different types depending on the type of switch your third channel has. https://www.ebay.co.uk/itm/Two-Channels-LED-Lamp-Light-Control-Switch-for-Traxxas-4-4-RC-Crawler/323561992325?hash=item4b55cc3085:g:eRUAAOSw6N9eouSV or https://www.ebay.co.uk/itm/1-10-RC-Rock-Crawler-Accessory-LED-Headlight-Lamp-3CH-Control-Panel-for-CC01/192629858344?_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D20200513093106%26meid%3Dcff9183af30a450185398b5d8c5c6912%26pid%3D100005%26rk%3D5%26rkt%3D12%26mehot%3Dco%26sd%3D323561992325%26itm%3D192629858344%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebWithBBEV1Filter&_trksid=p2047675.c100005.m1851 Sorry if I have pitched my answer too simple but hope it helps.

Mack1 Posted May 21, 2020 Share Posted May 21, 2020 I'm assuming when you plugged the lights into the 3rd channel on the rx the lights came on but would not switch off. If that's the case then what CarlC has said should work ok. 1 Quote Link to comment Share on other sites More sharing options...

That's excellent thanks. No, you definitely haven't pitched it too simple. So once that's installed I SHOULD be able to use the CH3 aux switch to turn them on and off? I shall get one ordered, asap. ✊😷👍 Quote Link to comment Share on other sites More sharing options...

Fat Freddy Posted June 6, 2020 Author Share Posted June 6, 2020 Hello folks, bought a cheap switch off eBay. Didn’t work. Not 100% sure if it’s the switch or the transmitter at fault but am just going to forget the idea for now and settle for having lights on constantly. Maybe if/when I get a new/better transmitter I’ll try again. Quote Link to comment Share on other sites More sharing options...
Hell horn. Posted June 6, 2020 Share Posted June 6, 2020 If you want to control the lights. You can get a rc4wd wireless light controller. Plug it in to your rx to power it. Then you can use the little remote to control 4 different lights with it. I use them on my cars. Works fantastic Be about £25 to 35 for one. Depending on where you get it from. 1 Quote Link to comment Share on other sites More sharing options...
