Default Fancy foam Gernot milled yak 55

I bought it milled without a paint sceme to save as much weigh as possible, as you can see I did my own paint sceme with markers. I have a Cobra C-2202/70 brushless motor, a Hyperion 180 mah 25C 2 cell lipo, a 2.5 gram 72 MHz receiver, a castle creation 6 amp esc ( soldered directly to the motor, and I am going to use two 2.9 gram servos on the tail and a 4.4 gram servo on the wing. The weight with the motor, esc, completed airframe, lipo battery, and receiver is 3 ounces, I am hoping for the total weight with the servos to be below 4 ounces. The motor draw 3.01 amps at full throttle with a fresh battery and a 7x3.5 GWS prop, I am going to try to get a 120 mah 2 cell lipo to save another few grams. The plane has a wingspan of 32 inches and a wing area of 350 sq. inches. The motor produces 6.4 ounces of thrust at full throttle so I'll have at least a 1.5 to 1 thrust ratio.
