Can someone tell me what "IMAA legal" means when reffering to some planes? Also what does a 12A size plane mean?

Thanks,

Troy.

Troy,
Greetings and welcome to RC Universe and RC as well.

IMAA is an organization that promotes fun flying of giant scale model aircraft. The minimum size for a monoplane is 80" wingspan and 60" for a biplane. True 1/4 (quarter scale) is also allowed by the rules so an Extra will make it in at about 73" or so. Most flying is done with much larger aircraft however. See the website http://www.fly-imaa.org/index.html

You wrote 12A size in your question.
Do you mean 1/2A (normally referred to as "half A")? If so this means planes that are of a small size and use engines in the 0.049 ci range of engine displacement. In the airplanes discussion form see the following: http://www.rcuniverse.com/forumdispl...s=&forumid=161

Hi troyp,you may want to join the IMAA,the magazine alone is well worth the price and they have some great building articles.

Thanks Excap yes I did mean 1/2 A. But now since I have read your reply I have noticed a few other words in your signature file that I would like to know the meaning of. They are
IMAC and Pattern? What do these words mean?

Thanks,

Troy.

IMAC = International Miniature Aerobatics Club
Pattern = Precision Aerobatics

The first one involves scale aerobatic planes (Extras etc) and Pattern involves non-scale planes. The object in both is to fly perfect aerbatic figures.

Hi Troy, your a long way from civilisation, i take it by your Q's your a reasonably new flier? have a look at www.spadtothebone.com when you grow out of your trainer

Good information already given. Adding the following links:

IMAC is also referred to as "Scale Aerobatics" and we use models that represent full scale planes. http://www.mini-iac.com/main.asp

Pattern uses purpose built planes that fly very smooth manuvers. Also referred to as F3A for international competetion.

The forum these are listed in here also includes 3D which is know as Artistic Aerobatics. http://www.rcuniverse.com/forumdispl...?s=&forumid=31

For additional information see what we fly at the following club websites:

Woodsy,
I used to live over your side of the country in Noble Park near Dandenong before moving to Broome in 1990. I have already built myself a SPAD in case I ever crash my trainer.

Troy.
