wings,
I forgot to answer the last part of your question--(All gas planes have ailerons? )

I belive your'e asking about glow trainner, also do you have a radio if so how many channesl?

No, Lot of the trainners usely have three channels or four channels-includes airerons.

For three channels- Sig Senior Kadet 78" wing span- a great plane very gentle flyer,
Carl Goldberg-Eagle 2- 63" wing span- three or four channels.
Great Planes PT-40-MKII- 60" wing span- three or four channels.

You can find these planes at a hobby shop in your area, or in Tower Hobbies Cat. or their web site towerhobbies.com.

It's better to learn with a four channel set-up with engine, elevator, rudder, and airerons.

Hope I answered all the questions you had.
