Alan,
I am glad to see that your E-Vector is moving forward. I agree with your thoughts on Mica film. It looks great and adds a tremendous amount of strength.
We are currently flying an ARF Brodak Vector using the same Brodak SC motor and battery that I use in the E-Oriental. It flies great with that power system using the 10 x 5 prop and 63' lines. I feel it would be better to go to a 4S 2500 and 1000-1100 Kv motor to lighten up the system and use an 11 x 5.5 prop. The Vector really likes to fly @ 5.0-5.2sec/lap on the 63' lines.
I look forward to hearing your results with the Scorpion motor & 3S battery. I was very impressed with the power and quality of Crist's Scorpion motor in his barnstormer. After seeing the motor in person, I understand why they are a great choice of quality ECL motor.
My Uncle Dennis' Swinger used a Rim-Fire 35-36-1200 and a 4S Flight Power 2500 pack on 61' lines @ a 5.1 lap time. His flight used only 1800 Mah for the pattern which includes 20 laps after the pattern (6:00 timer). The E-Oriental 3S for the entire pattern on 63' with the Hublin timer uses 2400 mah @ 5.3sec/lap. On 60' lines & the same 5.3 lap time on the Oriental only uses 1800 mah. My timer is set for 5:35 which gives me 4-6 laps after the clover.
