|  servo power
so i recently got a losi night crawler and have noticed that when im makeing a climb and my steering gets into a bind and i notice that all the pwr to the vehicle is cut out. but if i release the steering i can go again. i ordered a hitec hs7955tg servo with the hopes this wont happen. but is it still gonna happen because of no bec unit? a couple pics from my second session as my buddys dads house.  http://i1080.photobucket.com/albums/...Picture015.jpg |

My guess (more than likely correct) is the steering servo load is "browning out" your RX. This can be fixed by an external BEC. I had the same thing on my rig, big steering loads caused the rig to stop responding, if I lifted the front wheels up it worked again. I finally noticed that when this happened, the RX lights went off due to brownout, lift the front wheels up & the RX lights came back on. Fixed by adding a CC BEC.  I wired the BEC direct into the steering servo, thus I don't have to worry about what my RX can/can't deal with. |

I had the same issue, i'll never build a crawler without an external BEC again (unless I build one with a BRXL)slamming in a bigger servo will only make it worse, get a BEC along with that servo and you'll be golden. (if you want to be a cheap ass, you can try one of these http://cgi.ebay.ca/HOBBYWING-UBEC-5V...item2a0ead15bd I have a friend testing one out and so far its been pretty good, I myself use 10A CC-BEC's in both my rigs) Last edited by fred0000; 03-13-2011 at 03:39 PM. | |
