relays

[Bodge Job]

i bought two 100 amp relays, and thought they were SPDT but they turned out to be SPST, is there any way i could wire up a motor for two directional drive? i cant think of any way without diodes is there a way im missing, or should i just by some SPDT relays?

Re: relays

Using SPST relays you will need 4 relays to be able to have 2 directions. Using SPDT you only need 2, like i use in Primogenito for the drive instead of ESC's.

Re: relays

I don't know how stores are there in the UK, but here, if you explain that you bought the wrong product the majority of the times they exchange for the right one (some stores act like a**holes and say it was your fault...).
