BB gun not firing .

[blimp]

Hello everybodies , much funnage was had this afternoon , despite working perfectly yesterday the BB was stone dead when i tried it out today (new 3800mh battery) first thoughts were , wonky wire or i'd fried something . So it was out with the multimeter , sure enough there was zilch on the yellow pin out of the RX18 , everything else was fine . Both spares had the same bug . too much coincidence . New recievers made no difference , new looms etc. same result . then the penny dropped and i dug out my spare tranny , problem solved ! re checking showed all was well with all of 'em . Just the 'up' stick on the old set . so if your pussy cannon dies it might not be the tank's fault at all . ho hum , more spaggheti juggling tomorrow then . Don'tcha just lurve electrickery .
