BASS 666 Posted August 16, 2013 Share Posted August 16, 2013 guys I bought a hpi mini failsafe for my hpi pulse cause I had a run away not long ago. the built in failsafe was going to throttle on when I lost signal so I set it to go to brake on. then I read that the built in failsafe only works when you loose signal so I bought the hpi mini failsafe in case I had a voltage drop. so I put the mini failsafe on and it doesn't work it just makes my servo twitch like mad. I have tried to set it a few times and it still wont work. my mate has the same set up and also bought a mini failsafe and his is the same. my question is ???? is the failsafe not working because I already have a built in failsafe ? thanks guys..

PurcyP Posted August 16, 2013 Share Posted August 16, 2013 those fail safe's dont work well with 2.4ghz built in 1 should be fine Quote Link to comment Share on other sites More sharing options...
BASS 666 Posted August 16, 2013 Author Share Posted August 16, 2013 those fail safe's dont work well with 2.4ghz built in 1 should be fine yeah its fine for signal loss but what about voltage drop. I must say im a bit pi$$ed off at the guy that's selling them on ebay. he should say they are no good for 2.4ghz after all that's what most people use..

PurcyP Posted August 16, 2013 Share Posted August 16, 2013 Voltage drop i dont think it does no, however voltage drop becomes quite apparent as youll start to lag as such but shouldnt loose control of the car, that point you should bring her in and change batteries Quote Link to comment Share on other sites More sharing options...
fatboyneil Posted August 16, 2013 Share Posted August 16, 2013 The built in failsafe conflicts with the external one you want a voltage safe think modelsport sell them now http://www.modelsport.co.uk/mtroniks-micro-voltsafe/rc-car-products/375356 but you'll need a power cap to stop the servo twitch http://www.modelsport.co.uk/spektrum-receiver-voltage-protector/rc-car-products/25493 but these can be found cheaper on eBay Quote Link to comment Share on other sites More sharing options...

J.K Posted August 17, 2013 Share Posted August 17, 2013 Unless you can find a way of switching your built in failsafe off....depends on what TX you have I guess! Quote Link to comment Share on other sites More sharing options...
shaanaleem92 Posted August 17, 2013 Share Posted August 17, 2013 Some built in failsafe works for drop in voltage Where the servos automatically return to netrual position when voltage drops to a certain point, but I dont know which onrs these are Quote Link to comment Share on other sites More sharing options...
