A standard glow flight will be 10 minutes. Most electric flights only last 8 minutes. Then to go up again you will either need to recharge the pack (takes about an hour) or bring extra packs with you that have been charged before you bring them to the field. A standard training day consists of six 10 minute flights so for electric you will need 6 battery packs just for the plane! To go up again with a glow plane, just refuel and go. Also unless you upgrade your electric motor, esc, and battery your electric trainer won't have much reserve power if its windy and you need to fly against the wind to get it back to the runway. At the end of the day you will need to recharge your transmitter and all your plane battery packs. With a glow plane you recharge the transmitter pack and the reciever pack and your ready to go. Bottom line, if your really set on e power planes, it will work but glow powered planes provide superior performance for the price and are are less problems for starting out. [8D]
