everclear1984 Posted March 4, 2017 Share Posted March 4, 2017 Can anyone shed some light on why this is happening? I've tried the radio gear shown in the vid as well as my Spektrum rx/tx and both have the same issue. Quote Link to comment Share on other sites More sharing options...
froggy8 Posted March 4, 2017 Share Posted March 4, 2017 its not binding or power shortage is it? Quote Link to comment Share on other sites More sharing options...
m4inbrain Posted March 4, 2017 Share Posted March 4, 2017 Power would be my guess too. Did that problem just pop up or did you change a servo or something? Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted March 4, 2017 Author Share Posted March 4, 2017 Only just got the car, first time powering it up. All batteries fully charged, 3300mah 3s lipo in car (don't have a suitable 2s) and 3s in transmitter. Nothing binding, it moves freely by hand.

froggy8 Posted March 4, 2017 Share Posted March 4, 2017 got another servo you could try on the steering? Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted March 4, 2017 Author Share Posted March 4, 2017 I think you might be right with the servo. Either that or the only other servo I have isn't fast enough to draw enough power to be an issue. Quote Link to comment Share on other sites More sharing options...
sunny Posted March 4, 2017 Share Posted March 4, 2017 What make model servo is it Quote Link to comment Share on other sites More sharing options...

Beige Posted March 4, 2017 Share Posted March 4, 2017 That looks remarkably like an overheating linear regulator. Most of the little 1A BECs are nothing more than a LM7805 or LM317. They're good for 1A for spikes, closer to 500mA for a few seconds from a 6 cell NiMh... Wagging the steering back and forth will be pushing it a fair bit. when the regulator gets really hot the output gets limited until it cools a little. Swap the ESC for one with a switching BEC, or run a separate one. Job done. Quote Link to comment Share on other sites More sharing options...
