Beginners are advised to begin their flying with a docile rudder/elevator model - NOT an aerobatic model.

Did you read the bit above? I'm assuming you can fly a docile model - I'll now give you some brief hints to assist you flying an aerobatic model.

I am referring here to planes which have ailerons and are designed to be thrown into the sky into aerobatic manoeuvres and (in the case of powered models), generally flown whilst under power. But before I start - I want to differentiate these from large gliders with ailerons.

Before we start - gliders with ailerons are not necessarily "aerobatic", but do have the ability to do aerobatic manoeuvres if they have sufficient speed and height. In particular, they may be more easily flow upside down and can do rolls, albeit generally fairly slow rolls because of their long wings.

Basically, Gliders with ailerons are generally flown in a similar fashion to polyhedral gliders, in order to minimise height loss. This means big wide sweeping turns and actually minimising aerobatic manoeuvres.

You will notice that a polyhedral model is almost "self righting", but anything with ailerons will generally require the pilot's input to correct any misdemeanours.

Two particular advantages of aileron gliders, firstly that if it is windy they are generally more stable, because wind from the side does not put them into a bank, and, secondly, they are less prone to turbulence when landing, because it is possible to level the wings with the use of ailerons provided airspeed is maintained.

Okay - let's start. As I said, I am referring here to planes which have ailerons and are designed to be thrown into the sky into aerobatic manoeuvres and (in the case of powered models), generally flown whilst under power.

You can also use the "stick under the lower wing" trick to hold them flat when they are coming towards you.

Make your plane (a) easy to see in the sky and (b) have the bottom a colour which is very different to that on the top. (This could save your plane - see below.)

Generally these models have a heavier wing loading than trainers - ie they have more weight compared to their wing area. Consequently, their stall speed is higher - and if you fly them too slow then they will fall from the sky - very quickly. So both launching and landings need to be faster. 

Until now you've been flying planes which have allowed your eyes to see what is happening, you mind to assimilate all the data, and for you to figure it all out before making your corrective action.

Because aerobatic planes fly faster and change direction more quickly, it is important that you hold your plane steady - still making the big wide turns that you were used to in your trainer. 

Things happen fast and you need room to recover / plenty of margin for error. So play high. To give your brain one less thing to think about, having the top and bottom different colours will allow you to easily determine whether you are flying upright or inverted. 

Stick to basic flying for quite some time before doing manoeuvres, and, once you begin doing them, don't do too many in a row without a break as before you know it your brain will be in overload, you'll lose orientation and down you'll go. 

I'm not going to try to take you through all the manoeuvres, just to touch on some concepts so that you will learn quicker when you are under the instruction of your mentor.

Rolls require height (to give you a healthy margin for error), speed, (a) so that the plane will respond to your instructions and (b) so it won't fall below stalling speed during or just after the manoeuvre.

Turn the plane on its back and continue the roll until the plane is upright again. Simultaneously, as it rolls on its back, you may need some DOWN elevator to keep the nose from dropping.

You can get inverted in different ways. One way is to start with a half roll, then bring in the down elevator to keep the nose up. Get out of it by a half roll to right your plane, or up elevator to tuck downwards back into normal flying.

Another is to start level and upright and have plenty of speed and then up elevator until the plane is on its back, then hold in down elevator to keep it level.

If the plane slows whilst upside down, release some down and allow the plane to speed up.

By now you will have figured two things - firstly that there are a number of things to think about in a short space of time, and secondly that height is essential to give you a health margin for error.

There are others - but these are beyond the scope of this site.

(The purpose of this site is to get you to a stage where you can fly safe and to make your own contacts to move forward from there.)
