I just bought a U-Can-Do 3D .46, but i havent finished purchasing the required hardware for it. I just wanted to get some feedback on the setup I plan on using to see if there may be better alternatives out there. So here it is:

Saito .82 w/ Perry VP20 Pump
6 x Futaba S9451 Digital Metal Gear Servos (97oz @ .13s @ 4.8V)
Futaba 1.5" Aluminum Servo arms for control surfaces
Futaba 1" Aluminum servo arm for throttle
Hydrimax 1650mah 4.8v RX Pack
Futaba 8UAF
Tru Turn 2.5" Wide Spinner
APC 15x4W 3D Prop


My only real question is whether or not the 1.5" Futaba servo arms are too much. They are 1.5" to the first hole, so about 2" to the outside hole ( http://www.futaba-rc.com/parts/futm1980.html ). The metal gear 9451's should have enough toque to work with them - I just dont know if i need arms that long, or if the 1" ers will get the job done. I dont want to have to crank my EPA's all the way down and lose all that resolution if i can get maximum throw out of the 1" arms.

I know the spinner is the wrong size, but there is no way im going to get a 15x4W to work with a 2" spinner, there just wouldnt be any spinner left. It actually doesnt look that bad up against the cowl. I am also aware that a 9451 is overkill for the throttle, im just tired of the slow response of the 3151 SX that i have on my Matt Chapman Cap 580 throttle, so i figure ill just get 6 of the same servos.
