Werner, as your 'located' in south africa, i'd get a Shotgun 2. There absolutly great, weigh nothing and and you have to build em. There cheap to run as the only need a 36 size 2 stroke.

If you dont want to build but want the best ever performance ever buy a Weston UK Cougar 2000 with a west 36t1, throttle pipe and a 11x4 prop. This will give you instant throttling with 7.5lbs of thrust on a 3 and a bit lb plane.
