Lets get back to basics part 1

The inside loop:
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.
Below is the inside loop on video (on the RealFlight G4 rc flight simulator), including close-ups of the tx stick inputs and the airplane's response...
