Prism Brasington 9' Taz Delta excludes LinesThe new Taz Delta is pretty big, with a wingspan of 270 cm, and it's quite stable in the air, thanks to its extra large keel. It's made from 70D polyester and has 6 mm fibreglass rods, so it's really strong and a lot cheaper than the nylon and carbon fibre version. It's a bit heavier, but it takes off pretty early. Its three tails follow the flight path and can be joined together at the end of the keel rod instead of being attached to the wing tips.
