Hi:

Thanks for your reply, his retail price is very close to "helihobby"s price, but some are little high, but every thing are in the package plus those upgrades.

I've checked the price shuold be around $1200, and his selling for $630. I think that's pretty good. And it seems that all parts are very clean and new. And the seller only have one bad feedback when he first time bid other's stuff.
