I acctualy got the relays wired right! By dumb luck, I am sure, the wireing on my speed control was done correctly. I had it looked at and approved by the rc gurus at the hobby shop..... .....but alas, no complete victory for me. Upon attempting the maiden drive of the Sherman, no bells rang and no flares flew, ..... nothing. My MRC (mini relay controler) from Anvilus was a dud. No current was abble to pass through it's proud curcitry as volt meters pried for signs of life from with in. Without this crutial component I am dead in the sand. A replacement must be sought forthwith that I may roll through the town streets in triumph with my armored steed.
