So I've done a handful of mods to my lovely truck here and somewhere in the middle I done goofed good. Could use advice and help to figure out what went wrong where if anyone knows about my issue.
On a fresh new pack the truck runs fantastic, after a minute or three it studders like it's signifigantly low on battery power, give it a little less throttle and it runs good for a few seconds then it's bad. give it hardly any throttle and it runs fine for a minute or two and studders.
its got a sever Jerk jerk jerk jerk issue.
The lights twitch with the motor motion so I think it has to do with my Receiver not getting consistent power.
It has done this WITH a Ubec, and without.
it's also done this on both a 6 and 7 cell Nimh pack (Lipo cut-off is OFF)
things that changed since it last ran good:
1.(don't cringe) I liquid electrical tapped the reciever, seen it done quite a few times and it all worked for them. it sat for over a week before i ran it again so I know it was all dried by then.
2. Installed (then removed) a Ubec.
3. installed a Traxxas style battery connector. (issue occured with my old Tamiya style connecter as well, so I eliminated it as a possibility.)
Nothing is warm to the touch, so I don't think heat is an issue, and the ESC does go through all the binding steps and programming just fine.
but I can't take my rig out when I can't drive it!
Any tips or advice here?
EDIT: added video
Video of the issue, pardon my AWEFUL video skills but there isn't too much to see.
