OK 60 size is the red-headed step-child in RC- (No offense to red headed step-kids and what not

)
There are fewer 60 sized airplanes than I would prefer- Since you are leaning towards the 61FX and OS-70 Surpass that means you do not have either yet, yes? If you are on a budget or expect that while learning Pattern/3D you may crash a couple airplanes I would ssstay in the 46 2cy. 72 4cy. class-
The U-Can-Do comes in 46 and 60 sizes, they both fly great and fit your specs to a "T", but I would go 46 if you are gonna run the 61FX or OS-70 4cy.
Profile planes are easy to build and you can fly the snot out of them--- an OS-70 4 cy. on any 46 sized OMP profile, Morris profile, etc. will teach you quickly what a great flying 3D plane is like- (I like the Saito-82 or YS-63S/FZ however-)
I think the key is really: What type of flying do you enjoy, or what type of flying really interests you?
If you like pattern flying with some precision a Javelin or Zen-50 would be great-
If you like to learn all the crazy 3D maneuvers everyone is always talking about a profile is the way to go-
If you like an airplane that flies everything pretty well but LOOKS like an airplane, the Funtana-40 or similar fits the bill-
This is a fun and popular topic, keep us posted!
