The Trojan is a great flying plane, but unless you have a lot of space ( e.g. ACRES of land ) in your back yard, it may be too big for many residences.
In our area flying a Trojan or almost any plane will cause the Park Police to permanently escort you out, never to return lest you face a big fine.
However our club members fly the Trojan's all the time at Fun-Fly's... they are a riot when grouped together....
I really don't see anything at HK that I would consider suitable for an area less than 1-2 acres.
For the latter you want a Slow Stik or Micro-Flyer.
