Depending on your Budget, here's the ideal set up:
Basic Kit-
-Hitec hs 81 servos, metal gear for cyclic, plastic gears for tail ok. (You'd have to modify the crutch to use your Pico servos, I would definitely not recommend using those)
www.servocity.com has free shipping
-Kyosho Atomic Force motor, Roffeetv should have in stock, if not towerhobbies has for $20
-35amp, esc, Castle Creations, Pegasus 35 is probably best for price, Roffetv may have these also.
-Futaba gy240 Gyro is a great entry level hh gyro
www.helihut.com has for $95+shipping.
You'll just need some thin and thick CA glue, maybe some spray can paint for the crutch, if you go with a brushed motor, paint it black otherwise you'll get stains from the brushes with a light color. Other than that, basic tools and a metric ruler. (Dremel, if you go with the gy240, you'll need to make a gyro bed, really easy. JR voyager e landing gear is really nice too.)
If your budget allows go straight to brushless
Most inexpensive will probably be a Mega 16/5/3 set up (about $160 or so) next, Astro Flight 020 (more power) set up, about $200.
Your radio will be just fine.
And you'll need 7 cell packs, connectors
