The inside loop is the easiest of all stunts to pull off, and any rc airplane with elevators is capable of looping.

How to do it: Start by flying straight and level into wind.
Open the throttle to full power and, at point A in the picture above, pull back on the elevator stick to start a climb - not too suddenly, be gentle but definite. Keep the power on. The airplane will go into a vertical climb, let it keep going until it starts to roll over onto its back - point B in the picture. At this point, close the throttle and keep holding the elevator stick back, adjusting it as necessary to maintain a tidy path.
At point C in the picture, level out the airplane by returning elevator to neutral and increase power to exit the loop, flying straight and level again.
