Maudib ... only great candidate and affordable is the Lanier Laser 200, it should come in at 9.5 lbs with as 120 4C, hence with perhaps a MVVS160 gasser it will be about 10.5 max. Pretty good for a 72" plane! The EF Yak 68" with a YS110 is only 8.5-9 lbs. Again a 160 gasser there might be a slight overkill.

The MVVS 160 gasser with tuned pipe will haul a 15 lbs plane with no problems, not that it will do unlimited verticals.
