Can you do an 8 piont roll or multi roll..like 4 consecutive rolls without loosing altitude,
tail slide or a torque roll , hover, lumcuvac on a 4* yet ???
Or a nice humty dump or maybe a nice snap roll right at the top of the humty dump.
or a lumcuvac into an inverted flat spin
My 4* is capiable of all those manuvers...I bashed it thou

I only reason i don't like bi plane is storage space.
I had an ulitimate and a pitt.
Once you get all together..you won't really want to take it apart.

The Something Extra or any profile type models are nice to have. I extended the ruddesr...of course.
The profiles type will do better kinfe edge becuase of the body, but they're one piece.
The SE comes apart for better transport and storage.
These type of models still retains a straight wing chord .
The air foil are thick. You can toss it all over the place and they land like kittens.

A scale type model with tappered wings..you'll get a snap of sorts if you're not careful.
taking off and landing one these is totally different from your trainer.
