ok so you hate trainers.... yes... they look ugly but that can be fixed.

take your standard pt-40.. and convert it to a tail dragger... this will make it a bit more difficult to take off but you will learn quick enough with practice.

now cover it white with a red nose and tail. throw some mil markings on it and abracadabra, a stand-off L-21

the ease of learning on a trainer without the "ugly trainer" syndrome.

note I picked something that would be bright and easy to see against the sky and the treeline... a camo job can make landing in front of trees a bit difficult for a new pilot.

you can go with the cub if you REALLY must have a scale plane. alot of people think cubs are hard to fly but thats not the case... they just have some quirks you need to figure out.

a: they like to groundloop.
b: you need to co-ordinate your turns
c: landing they are prone to noseing over if you are carrying too much speed...
d: they dont like to slow down.... its not that they fly bad when slow its just that they dont like to loose any speed... they just glide and glide and glide and glide....so slowing it down to land takes a bit of practice.
e: crosswinds can be FUN... and by fun I mean "how the @!#$ am I going to land a plane that is crabbing 45 degrees to the runway" fun

so if you MUST ABSOLUTLY NEED to go scale a cub is probably the way to go. and besides... I think everyone needs to fly a cub, its just something that RC pilots do....
