Renaultk4j Posted April 19, 2014 Share Posted April 19, 2014 Hello guys and girls of msuk! I have a problem with my throttle/brake servo. It's a new servo, the problem I have is that when my transmitter is shut off the servo goes to its default setting, such winds the throttle open, it did this yesterday resulting in a runaway. I have adjusted the bar that sits on the servo but this prevents the throttle opening past around 25%. I'm hoping that this is an easy fix to the more knowledgeable folk here. Thanks!

Thunderwolf Posted April 19, 2014 Share Posted April 19, 2014 1. reset your fail safe, that what is causing this to happen 2. don't be an idiot and turn off the transmitter before shutting the engine off and turning of the car first, transmitter on first and off last - first rule of rc 3. http://www.msuk-forum.co.uk/topic/187905-switchblade-ignition-kill-switch-failsafe/ - buy one of them and fit it so if you do switch off your transmitter or the batteries die in the car or transmitter than instead of relying on your failsafe this will just turn off the engine, no engine, no movement Quote Link to comment Share on other sites More sharing options...
Renaultk4j Posted April 19, 2014 Author Share Posted April 19, 2014 Cheers for the reply! I don't shut off the transmitter first usually, I did that whilst the car was up on top of my tool box to try and make the problem appear, as if it had gone out of range or similar conditions, as I'm unsure why this problem has occurred. I don't currently have a fail safe fitted to the car (I know, I know, stupid, lesson learnt) Thanks again for the reply! Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted April 19, 2014 Share Posted April 19, 2014 ah ok that fair enough, first post made it sound like you just turned it off and it shot of across your bash spot lol what car/radio you got? most models have a built in fail safe function these days and is set when you bind the tx and rx together Quote Link to comment Share on other sites More sharing options...
Renaultk4j Posted April 19, 2014 Author Share Posted April 19, 2014 Hey no problems dude It's an FG Marder I have, it has a Spektrum dx3 tx and Spektrum rx. I am guessing this is quite an old set up I'm using. On the old servo it used to go back to idle in these situations, but is on a new servo from an encounter with done water (rx box was dry so I don't think the rx took water) I'm just stumped with it and I'm currently looking to sell the car and move over to planes, but I won't sell it until I have this issue fixed. Thanks again. Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted April 19, 2014 Share Posted April 19, 2014 my first step would be to re bind the tx and rx, making sure not to touch the trigger doing it, or hold trigger at half brakes. this will reset the failsafe setting which is built into your radio, if not then i would look into the servo and its settings, for example did you mess around with the trims at all?

Renaultk4j Posted April 19, 2014 Author Share Posted April 19, 2014 I'll give that a whirl, would that set it up so that it'll return to idle rather than blasting across a field? I haven't messed with the trims. Thanks again for the reply awesome advice there! Quote Link to comment Share on other sites More sharing options...
Thunderwolf Posted April 19, 2014 Share Posted April 19, 2014 if its the failsafe that is causeing the problem that will fix it. if it doesn't then we need to look else where. Quote Link to comment Share on other sites More sharing options...
Renaultk4j Posted April 19, 2014 Author Share Posted April 19, 2014 I'll give that a try and report back, cheers Quote Link to comment Share on other sites More sharing options...
Renaultk4j Posted April 19, 2014 Author Share Posted April 19, 2014 Just rebinded the tx and rx and it now failsafes back to idle, thank you very much for the help! Quote Link to comment Share on other sites More sharing options...
