Yup, day VFR only due to single instrument power source (electric). Otherwise very similar to a C152: if you fill it up and put 2 real world blokes in you will be over the limit but it will fly just fine (so I'm told of course). The big difference is in fuel burn/endurance figures which compare very favourably (approx 3:2 with C152 if that makes sense). Don't think the Rotax likes working too hard though (i.e flying club environment), however visibility is peerless, it has a stick and it's more comfortable than a Cessna. Not aerobatic though, in this country anyway. Of the two I'd choose the Katana.
