Around this size of motor works great in balsa tissue models. I like the rule of thumb of a 100 watts per lb. An average out runner can consume about 3 watts input power per gram of motor weight. A 10g motor is good for about 30watts, a 40g motor would be good for 120W in (constant not burst). Just good rules of thumb, your results may vary. So a 16g motor providing 48 Watts input power in a 1/2 pound (8oz) model works out well. Get the weight of the model and do the simple math to chose the right weight motor. Than you'll have to figure on a Kv. With this type of airplane I tend to go with the lower Kv motor so to be able to swing a larger diameter, lower pitch prop. Hope this helps[/QUOTE
Do I consider the total weight of the plane including Battery and motor? I don't think it will even be a pound, very light plane. The guy who built it really knew what he was doing.
