Here's an example for a gasser...My ship: Predator Carbon SE w/ Zenoah 231 and the "Agrav8" upgrades that come with the kit from Rick's...ie 720mm carbon mains, 115 carbon tail blades, metal A-arm
-Tx: Futaba 9CHPS
-Rx: Futaba 149DP
Futaba 9251...rudder...comes w/ the 601 gyro
-Gyro: Futaba 601 setup
-Governor: Futaba GV1 w/ Stator Gator
-Raja's gen kit w/ custom carbon bracket for the electrics
-O'Neill Bros Racing UFO air filter
-All push/pull rods (except the throttle and rudder)changed out to titanium turnbuckles...easier to tweak.
In the hangar waiting for the time/crash to upgrade:
-Toxic Racing modded 231 w/ 257 carb
-Century all metal head
-Century metal tail gear box and HD boom
My recommendations for a .90 3D machine...carbon frame kit, OS .91 SX-H-C Spec w/ pump (I have no experience w/ this motor but it seems to be bad A$$), servos as listed above, Futaba 611 or 601 gyro setup, GV1, PCM heli radio of your choice, metal A-arm, and (if you don't go with the carbon frames) the front rudder servo mount kit.
