Tri-axle half pipe tipper trailer

[ricm]

since trailer will be wireless control, it needs its own power supply....so got the battery box mounted for the 7.2V pack. Decided to use this size to make sure the screw drive has plenty of punch....



Also making side cabinets to hide the battery pack and also house the batteries for the support legs and one side and on the other side the H-bridge relays for the screw drive with manual over-ride switch

finally got some meaningful progress, still won't be finished before Christmas though...

tipping mechanism finished and mechanically tested - over 50 degree dump angle. Haven't done a weight test yet but the mechanism worked fine using a battery that didn't even have enough juice left for a truck with MFU....
