RE: Glow-to-electric conversion guidance
Erik:
THEY (the experts) say it takes about 50 watts per pound to fly a airplane, that is just normal putt around. To do aerobatics THEY say around 75-80 watts per pound to do vertical stuff you need 100+ per pound. I have converted 1/2 A planes and used speed 400 motors and the planes weight is around 16 to 22 ounces. Watts(power)==volts X amps . Most 400 motors draw around 10-12 amps so if you use a pack that will put out 8-9v under load you have a pretty good flier. Most of todays motor manufacture will give you the watts that the motor is capable of so you can match them up that way. I personally like the outrunner type of motors of today (no gear boxes) and still pull pretty good size props. There are a lot of these 75 to 100 watt motors available today so the choice is wide open and they are getting really cheap and the ESC are coming down in price also. Thats the way I would go today...
Good Luck
Bob
