    small DC motor should do the trick. if you need more power (ie. doing acrobatics etc) you can look into brushless DC motors for helicopters. those things are beasts.

    A styrofoam wing that is only 18cm long is tiny.

    I have an RC Parkzone J3 Cub with a total wingspan of 45cm (22.5cm for each wing) and it uses a tiny brushed motor with gears to drive the 10cm long propeller. The brushed motor was also used to open and close a CD tray. The motor wears out its brushes in a few hours of running. I replaced the motor 6 times.
    The airplane with its 3.7V 120mAh Li-Po battery and radio control receiver and servos weighs less than 28 grams. It flys for about 10min or 15 min when there is NO WIND.

    I have two RC E-Flite model airplanes with wingspans of 44cm and 60cm that use very powerful brushless motors that last forever. They are powered from a 200mAh 7.4V Li-Po battery. Wind does not bother them. They weigh about 70 grams and 90 grams.
    I will fly them again now.

    To Panic mode and Adioguru,
    I asked in my first letter that That it will be of how price. Can you answer this??

    After all panic mode, I don't want to use acrobats in my plane.

    My first RC airplane is the Parkzone J-3 Cub. Its tiny replacement brushed motor measures 5mm diameter and is 15mm long. It comes with a brass gear and its wires have a plug.
    It costs $9.99US (535 Indian Rupees).

    The motor holder (with larger gear and propeller shaft) is also available for a low price.
    The tiny 2.4GHz receiver has the motor speed controller, elevator servo and rudder servo on it.

    What will be the weight of the motor?( I am asking this because I know that weight matters in all of it.)

    Can you say?

    Did you remember that I am making it of my own with thermocol?

    Any guidelines?

    I think your thermocol is the same as the styrofoam used to make the J-3 Cub model airplane I showed.
    My airplane is made in a factory. I cannot mold the styrofoam like that.

    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.
