Folks,
I bought a Spektrum DX7 and it came with four DS821 servos that I do not need. They're up on eBay listed separately. Please have a look if you're interested. These are 88 oz-in at 4.8V servos.
BIN is $25.99 each. I offer shipping discounts for multiple purchases. Here is a link to one of the listings. Click "View seller's other items" to see the rest.

Thanks for looking.
