We all start out that way. Go back a few years in my threads and you'll find me cussin' and swearin' at (silver) soldering. I still hate it, but I've attained a certain skill and I'm no longer afraid.

Before when you were quoting 7-8 servos that just seemed wrong on a 1/5 scale WWI fighter. On a 1/6 scale model it's usually 5 servos (throttle, aileron, aileron, rudder, elevator). With your model you could add one more for two on the elevator. If you need more power, just use more powerful servos. And the Saito 125 also sounded like overkill for this model. And the Saito 91 will be cheaper and might even fit inside the cowl. And you shouldn't allow yourself to think along the lines of: "I'll build heavy then stick in a BIG engine."
