reversed rx18

[spongehoobtank82]

Ok here's the problem- got a couple of old heng long tiger 1's cheap, no smoke and sound and the ancient soldered in rx13 (well am guessing that's what it is) thought I would upgrade it with the rx18 out of my crappy pantiger (am systematically robbing parts for it, its prob going to end up a shooting target for the bb gun!) anyway I digress! Now everything works accept when I push forward on the Tx its spins left, when I pull back it spins right, push left it goes forward, push right it goes back, crazy! Now it worked fine in the pantiger, the only thing different is I had to fit some plugs to the motors as the were soldered to the old board, I've tried swapping them over to no avail, anyone got any ideas? Cheers dudes

Two suggestions sponge.... switch the polarity on one motor only...or...swap the motors side to side

Hello Spongeboobtanks82 , Alpha is correct - the left motor has reverse polarity , a simple swop job

Alpha were half way there! I now have forward and backwards as normal but the steering is still inverse!?

Is this helpful ? -

OK...Now switch the plugs in the RX

. . . And if it now goes backwards instead of forward the red and black wires are the wrong way round on the motors ( the motor has stamped grooves on one side that hold the inner magnets - this double groove is nearest the motors negative pole ) B.

Thank you blimp... that would have been the next step
