KRs Hobbies just posted that they are taking pre orders for the upgrades mentioned. Just put in my pre-order for the grips, extended upper head, and blades. Also ordered some 850 15c batteries.

They will be in stock October 15th; ready to ship, according to Keith. Free shipping on orders over 100.00. Unfortunately, a hundred bucks is easy to rack up in any hobbystore shopping basket.

Will write a review; hope others do too.
