Oh How Original Posted March 8, 2018 Share Posted March 8, 2018 Not sure if any of you will know this, but I'm wondering if it's possible to turn on/off rear steering. Imagine for example, you want to drive along normally, with the rear servo set to centre and told not to move. Then flick a switch and it comes alive doing the opposite of the front. Flick the switch again and it returns to centre. Is this possible? I have a DX4C, so my spare buttons are 2 or 3 position and I was just wondering if anyone knows if it's possible?

norcoforever Posted March 8, 2018 Share Posted March 8, 2018 (edited) If you used a y cable meaning that servos at each end would to the opposite to each other due to direct could you then use a simple switch in line with the rear servo that in essence allows you to turn power to it on and off? The only issue I see is that it would remain it whatever position it was left when it is turned off. I mean this type of switch 222872097263 (eBay item number) Edited March 8, 2018 by norcoforever Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted March 8, 2018 Author Share Posted March 8, 2018 But that would surely turn the front servo off too? If I could turn it off in the position it's already in, that wouldn't be too bad as a back up option, as I could just centre the steering, knock it up, then carry on. I see where you're coming from though. Quote Link to comment Share on other sites More sharing options...
norcoforever Posted March 8, 2018 Share Posted March 8, 2018 Depending on how they work I'm guessing it just cuts the current if it was in line just on the lead to the rear servo I think the other side of the y lead would be unaffected Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted March 8, 2018 Author Share Posted March 8, 2018 Ohhh, bloody hell yeah put the switch into the servo then into the y lead, then to receiver. Derp moment hmmm, that is thought provoking. Need to buy some cheap servos to test, or borrow some from some vehicles, if I can be bothered with all those bolts 1 Quote Link to comment Share on other sites More sharing options...
johninderby Posted March 8, 2018 Share Posted March 8, 2018 Or get one of the new Flysky GT5 radios that lets you switch steering modes on the TX or an Absima CR4T which also has different steering modes built in. No setting up needed. John Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted March 8, 2018 Author Share Posted March 8, 2018 I like my DX4C too much and already have receivers etc... It's for a future project, unless I happen upon some very bargain pieces. Just in the thought process at the moment, I think what Dan suggested should actually do the job fine... Just need to do some testing. Quote Link to comment Share on other sites More sharing options...

If each steering servo is plugged into a separate channel, you can set up a switchable steering mix assigned to the switch of your choice. This is how I have the 4WS set up on my WR-01 and G6-01.

This is how I have the 4WS set up on my WR-01 and G6-01. What he said. I used to have that setup on my first crawler (that become my Bronco scaler). Could enable/disable the RWS at the push of a button. Plus you had the ability to enable/disable "crab" mode... for all the good that did!

atom3624 Posted March 9, 2018 Share Posted March 9, 2018 I have a 3-way toggle on my TXT-2, on a separate servo on the rears. It works but unless the suspension's tight and well-centred, it can look like it's 'crabbing' slightly. Fun for a while, but often revert to simply steering with the front's. Al.

Oh How Original Posted March 9, 2018 Author Share Posted March 9, 2018 Cheers chaps... I really must look into channel mixing too... Interestingly, in the 1:1 world, crabbing can get you out of a lot of situations... I was hoping the project in question was arriving today, but just had the post and it hasn't, so it'll probably be Monday now. Long way to go yet, but it gives me time to research and learn about it.
