RE: what do i need to get my slow stick in the air?
I fly my Slow stick with a Himax 20254266 gear motor, 8x6 APC Slo-Flyer prop, Phoenix 25 ESC, Hitec 55, 4 Hitec HS-55 servos, and 900mAh 3S1P lithium polymer made from cell phone batteries. Modifications include wing brace holders with no dihedral, ailerons, and Depron ribs glued under the wings between the ailerons and tips. Vertical performance is unlimited, as it takes off from a 4x4 foot table and goes straight up. Take-off rolls on grass are about 4 feet. 6-foot loops are easy, as well as inverted with flight with 25% down elevator. Rolls at speed are a bit over one second. Knife-edge is not possible. Flight times run from 8-25 minutes depending on how I fly. It's a blast for a cheesy little cheap airplane.
The Slow Stick will carry the HS-81s and 555, but they are overkill. If you have them, use them.
Brushless motors make more power and use less electricity than can motors. At equal performance levels, brushless motors run longer because they are more efficient.
