Balsa sheeted foam wings vs regular type ?
 

Im looking at a trainer by kyosho-- it has Balsa sheeted foam wings. . .

I'm a beginner too. Are these better than the regular wings, like found on the avistar or alot of other trainers ?

Are these stronger or weaker in general-- Recomment for them or against etc ... ?

Well, opinions vary as to which is lighter, but foam wings have been in use many years and are very strong. Think Surf Board. :D

They are also fairly easy to repair. Bottom line is that the wing will be fine and you have nothing to worry about if that's the trainer you want.

I personally dislike foam wings. I do not want to go to the hassle of sheeting one or using a cutter to make a core. I like wooden standard construction. Having said that the foam wing is very strong if done right. It is also easy to fix. Easier than traditional wood. I read here that foam tends to be a little heavyer than traditional wood. Kyosho has a rep for building a decent plane. I personally would not be afraid to buy and use one. I say use the foam and you should have no problems.

The foam core wings are bit heavier... but they are stiffer, stronger and will have a more accurate airfoil over the entire span.

There are trade-offs and the main one here is weight for strength. The foam filled sheet structure is rock solid. It is fairly rare to see a foam core wing fold up in flight. (unless you are REALLY abusing the model...)
