Deloiter, I have since got my mill up. The first day I had it up we had stronger winds than predicted. I saw constant 10a swinging near 15 in 35mph winds. When my batts got up near 14v I wanted to divert the power. I have a manual switching box. I switched off the batt connection and switched on the dump-load which was a car headlight. It popped like a fire cracker. At about 6:00 that evening the hub failed and I found it and what was left of my blades in a tree.
I have ordered another set of the same type of blades and a beefy 1/4 inch billet aluminum hub/arbor rig. I have been researching dump loads and since I dont drain off of the battery as a dump I have had to makesome assumptions. I bought 4, 55watt automotive spotlight bulbs and found a large computer power supply. This power supply was out of a server so it was about 430watts meaning it has two large fans in it. I gutted it replacing one of the fans with an eaven larger fan and using the onboard switch to operate fans. They are connected to batt power so I alwayse have fan power because the batts are alwayse full when the dump is on.
What Im worried about is when Im creating heat in the dump load I am also creating heat in my rotor and brushes. Ya know, Ive got to shut it down though.
What kind of dump do you have since you have about the same power output. Well sounds like I have a little better. Those six blade rigs are CRAZY POWERFUL.
