What will be the weight of the motor?My weighing scale has a minimum reading of 1 gram so the motor weighs something between 0.5 grams to 1.5 grams. The nylon motor holder with propeller shaft and larger gear weighs almost nothing. The 10cm propeller also weighs almost nothing.
The entire J-3 Cub RC airplane with battery weighs 29 grams (one ounce).
The 125mAh Li-Po battery weighs 3.4 grams. A 160mAh Li-Po battery weighs 4.1 grams.
The airplane has enough power to climb until it can barely be seen as a spec in the sky. When it catches rising hot air (a thermal) then it must dive to come down. It can do an inside loop. It can fly slow enough for me to run slowly beside it. It takes off from a picnic table or a parking lot.
The airplane is not made anymore but parts are still available for repairing it.
I think your thermocol is the same as the styrofoam used to make the J-3 Cub model airplane I showed.Did you remember that I am making it of my own with thermocol?
The battery on my small RC airplanes is held in the battery space with Velcro (hook and loop). The battery plugs into a jack on a cable of the airplane so it can be unpluged and plugged into the charger.Can you say where do I Put my battery?
