Ive been looking at Champs and Cubs. Seem perfect for the type of flying in my near term. Short local sight seeing flights with 1 child along, maybe grab some ice cream somewhere. I'd love to rent, but no LSA real close. In the Champs and Cubs, many seem to have an intercom temporarily installed. Is that battery powered? Do they have an external antenna for a handheld? Can the tower hear you/pick your transmission up? What about approach or center? Or is that rig mostly for nearby / in the traffic pattern. Last question - are planes Mfrd before 194x exempt from the Mode C requirement under the Bravo veil? If not, are you just banned? I'm trying to figure out if there is a way to make it work close to home. There's a Bushcat about 45 minutes from home. I'm hoping to get up in that in the next month or so, but 20 minutes each way beats 45 minutes.
