Speaker banana plug fix!?
Just got a new Arrma Vorteks and first hobby grade RC car. Motor to esc male bullet plug came unsoldered on second pack. Running 3S but only at 50%. Not hitting any thermal cutoff. Tried cutting back wire and re-soldering but cannot get my 100w station to put down enough heat on these wires to even tin them first, though I’ve soldered heavier gauge wire before so IDK. Done a lot of home theater speaker work and grabbed these beefy dual offset screw down banana plugs. They fit perfectly and are very tight with more contact area. Initially did just the one wire that came undone then ran it. Second plug came undone about 5 min into the pack. Went ahead and did the remaining two. Put in a warranty ticket but hoping this holds in the mean time. Not really sure why these come undone so easily.
