Kaos Arf
If you do a search you will find some postings on the original ARF from tower. A lot of people had problems. I received one of the first ARF's from Tower and I did not have any problems at all. It went together perfectly straight and the covering was super. I flew it for two years almost every weekend in nice weather and sold it to a buddy who still flys it and loves it. I used a Saito 56 on it and he uses a TT 46 Pro. The best thing I can say about it is that it flys like a Kaos.
Set up the throws right and its very gentle but a little faster than a proper trainer.
