| fxr issue? all lights blink..motor loses power..then runs
Ok so im trying to chase down this problem. . Fxr/35t on 3s with bec scx10 .. I ran like this for long time so not sure where its coming from all of a sudden. Problem motor loses power then comes back..when gone the esc blinks all lights. Tekin book says it lost signal I think ..using a 2.4ghz 4pl ..so im lost ..my esc rec bec are all in same box so there close and antenna is also in there..like I said never had issues ran like this for a year+ ..so I find it stange my esc is acting like its losing signals. .at 1st if I just touched or turned the wheels a tad like a small push it would go again ..thats the reason why I thought motor was bad..but last time it was just locked up like drag brake was on..with new motor 1st thing I did was clean motor that didn't help brushes were small and worn good so I thought maybe springs were to weak.. 2nd clean and check wires 3rd put new motor in..and run 30mins on 2 different lipos no issues then the 3rd lipo I ran my course stopped the truck walked away 3 feet and its dead again. So im thinking not a motor issue now.. Esc is waterproofed using dielectric grease inside of case ..and I do run through water..but since esc is in box it stays clean mostly ...im not seeing heat as in issues but hard to judge in a box through grease. . Im have a tough time with esc's this week rx8 blew out to I think..thats another thread lol Last edited by bronc4now; 07-08-2013 at 02:15 PM. |

Mine did something similar to this not long ago and the antenna inside the rx had a bad connection . I pulled it apart pulled the antenna wire and it was barely on the connector so I stuck it back and wiggled it a little and spun it to make sure it was on good and getting good connection, put it all back together and havn't had a problem since. Maybe this will help you. I use a 4pl and a 3pl so its the same rx's.

All LEDs blinking indicates loss of radio signal or the unit is overheated. My guess, if you were running HARD for 30+ minutes non stop, you probly over heated the unit. Would need some more details about what your gearing is, and your truck weight to tell if it could be a problem. If it is inside a box and sealed up pretty good, with the BEC and the receiver in there, I am betting it is a heat problem.. |

Sounds like a problem with the receiver, not the ESC or motor. Check the antenna is well connected to the receiver...

Uuu 3 good responses thanks..I like the receiver one tho..I hate the heat one becouse thats harder to fix.. And I do have dielectric grease on my receiver too so I can see how that wire can get loose and maybe lose connection. . Ill have to see if it was a signal loss my servo should not respond ether and a few times I think it did. . |

Ya its somthing with the wires ..its shutting on off motor sputtering when I jiggle the wires so ill clean it up and see if that helps I dont think its the receiver anymore tho Last edited by bronc4now; 07-08-2013 at 06:08 PM. |
