Sorry to hear that a couple have had bad experiences with your esc's...
Just to clear up the differences between the Hobbywing and the Orion stuff... Hobbywing produces the esc for Orion to Orion's specs. The Orion esc has higher quality internal components than the Hobbywing and the biggest difference of all is the software. It was 100% developed by Orion.
So, you might not see a big difference visually but there is in fact a BIG difference between the two.
etothez, be patient and give the replacement Orion a chance, although this has been a total pain in the ... I think you'll be happy once you have a chance to give it a fair comparison to the rest.
I highly doubt you'll have any more problems as long as things are good on your end.
