I am planning on changing my Wife's LT-40 to Electric for my Daughter to start on. My plan is to use my retired 10S pattern packs split into 2 5S 5000 Packs for power, These batteries are no longer suitable for high performance pattern flight but should be more than enough for training or sport flying. I have a Pheonix ICE 75 but nothing for a Motor. So, what would be a good motor for this setup that will give similar performance to the 46 glow engine that is currently in the airplane? What setup have others used in the past with this airframe?
For an inexpensive motor take a look at this one - $25 + shipping.

(More power than what you need [the motor is "rated" as .40 - .61], but will handle 3 - 6 lipo) Be advised that you will need to make accomedation for the shaft because the shaft comes out of the mounting plate end of the motor. You will either need to build a motor box or get one of the made up ones or make a protector on the inside of the fuselage so the battery does not accidently shift and hit the shaft. The prop adapter gets bolted on the end you see in the photo.
What you are actually looking for is a motor between 500 - 700 KV, between 500 - 700 watts of power (about 100 watts of power per pound of ready to fly weight)
AND WILL HANDLE A 5S LIPO. The difficulty is finding a motor meeting those specs is the 5S lipo - the
MAJORITY of motors that would meet your needs can only handle 3S or 4S lipo.
Hope this is of some help.
