I have an Eflite 110 on an old Modeltech Saphir II pattern plane (used to have a Bully 1.20 LS two-stroke / Bolly carbon muffler)). I have an 18x12 prop on it that has been sanded down to a 17x12. I have a cheap chinese high voltage speed control on it. I have used a variety of lipos (8 cell, 9 cell, and 10 cell). If I recall correctly, I am running around 55 amps. I have found that with Eflite motors (so have my friends), that you have to run the higher voltages to get them to produce. 8 cells don't cut it on my set up. 9 cells works fine for pattern but you won't be able to do much 3d. My plane weights 9.75 lbs with batteries. You will definitely want to use 10 cells. For 9 cells, I run three 3 cells in series, and for 8 and 10 cells, I run two batteries in series. Most standard speed controls are limited to 6 cell lipos. You will need a high voltage ("HV" version) to run 8 to 10 cells. I have 18C 4000 to 5000 mAh batteries which work fine for my set ups.
