encan, there are 1/2a (.049-.061) trainer planes, like the Ace series , whizard or grasshopper, you can see them at quantum models or the Herr kits (same place) , I have a Norvel .074 on my Ace whizard, it is a very popular kit,, go look at the 1/2a forum and do a search, some do fly at ball fields and parks, but I stick with the flying fields,, the whizard is only $35 from quantum and is pretty complete.....Rog
