I hope to return soon enough technical details. I've been fighting with a supplier. In essence I recommend against purchasing from Hobby King.
In my case they sent my orders to some address other than mine. Ultimately I had to have Paypal provide a refund, after Hobby King refused.
I hope that I can use Hobby King again in the future. I hope that their internal process become more reliable. And I hope that their support process improves to better handle (what I hope is) a goof.
(You can google for plenty of people who are much angrier with Hobby King, and will never use them again.)
