I suppose he had also inadvertently won the right to sell his knockoff motors as Velocity-RC/Arc manufactured products complete with defective bearings. And Paypal need not protect the buyer from fraud. Where's the accountability?
Rather than dwell on the past... I found that there is no better cure for anger and frustration than some reckless spending on more parts. I decide to take another recommendation from RcGroups and get some new quality motors and esc's. I will order in a pair of Arc 28-58-1 motors with a pair of Hobbywing platinum 100A speed controllers. I will savage a pair of WeMo's from the edfhobbies junk pile and mount and balance them myself.
Hopefully by then I can finally be off to the races!
I agree that the ARC's are great quality motors - I have one in a Wemo and it pulls around 2KW on good packs, also using Hobbywing 100A ESC. My only concern in your case is that you will be adding a fair bit of weight to your model. The ARCs weigh around 60g more (each) than, say, a HET 2W-20. Then there is the Hobbywing 100A ESC's which are fairly heavy in themselves and you will require 10 or 12 AWG wire which will all add significant weight. I honestly don't have any twin 70mm experience, but those that do will tell you that a lighter setup for a model of your size will be more suitable. Twin configuration does bring about some interesting efficiencies over a single and you really don't require 3+KW in a model of this size. 2KW will be more than enough IMO and you could achieve that with a much lighter powerplant.
