SATCH,
Before you spring for the high dollar name brand stuff check out Hobby King. www.hobbyking.com
You'll be able to equip your bird for about 1/3 the price of name brand or even less.

I have 60 to 120 and larger, VQ/Hangar9/NitroPlanes/etc. Even have one bird with a 9 1/2 Foot w/s. ALL ELECTRIC, and have had great luck with HK's stuff.

For example an AXI Gold 4120-18 from Hobby Lobby is on sale for $131.24
Motor from HK, Turnigy 50-55A, a 4120-18 clone is $29.99

Similar motor to the Hacker recommended previously anywhere from $60 to $120 from HK, I used the $60 versions on my VQ.

Packs, again the previous at $440.00, HK has em for $49.48 each or less then a C note for both.

I had roughly $1500.00 for motors/esc's/packs in my NitroPlanes 90" P-38, going name brand. AXI motors, Castle esc's, and Hyperon packs.
In my VQ 83" P-38 less then $500 going the Hobby King route, going Turnigy motors/esc's, and Zippy packs.

Thing too with the HK stuff, if something goes south, which call me lucky if you will but hasn't happened, you can buy 3 or 4 of an item for the price of a name brand.

Not to act like a HK sales person, I'm not, but hate to see someone spend big bucks when they don't have to.
