I've been flying my Sun Fli IV for close to three years now. Mine was also from a Bluejay kit. This was just about the best kit I have ever built. I liked it so well, I have built 4 other Bluejay kits and fould that all were fantastic fliers. I covered mine with Solartex with a GMS up front. The GMS isn't the most powerful motor out there but I cruise at about 65% throttle with no problems. I use an Airtronics padkage for guidance. Aside from a Blujay Lodestar 40 I use for orientation flights and relaxation flying, the Sun FLi is the best landing plane in my small fleet.
I'm confident you'll be more then happy with your choice.
