Advice on converting an Alpha 40 to Electric

I have an Alpah 40 that I intend to convert to electric. Does anyone have any advice in this area? I have looked at some combos and it looks like it will run somewhere around $400.00 for the motor,esc, and lipo. I am not interested in extreme speed, just dependable and long flights. I know I could just call Tower Hobbies and ask them, but that's too easy. Does anyone have a good source for (cheap) less expensive lipos?

Ted shuffled out of his cave and grunted these great (and sometimes not so great) words of knowledge:

United Hobbies has some very good prices on lipos, ESC and motors.

I would suggest a 4s lipo of about 3500 - 5000 mah, a 60+ amp ESC and a

600 motor. Use a 12x10, 13x8, or 14x6 E-prop depending on ground clearance. This setup will handle a 5 1/2 lb - 6 lb (glow weight) plane and provide 15 minute+ flights (depending on throttle management) as well as plenty of power for sport flying type aerobatics (loops, rolls, hammerheads, spins ).

The TowerPro 3520 would make an excellent motor for this setup (I have this motor in 2 of my 40 size conversions). It is your call on whether to run a separate receiver battery of use a BEC (some ESC in this size range do have built in BEC )
