I'm with Kevin, they were a POS when ABC Hobby made them but used to be easy to get under other names on eBay, the Stingray or Dolphin. When at the time even RCBM had a problem trying to make the boat look good in a review they had too many problems to be worth the money. The plastic hulls were vibrating apart within a couple of runs. The bushings in the lower units wore out quickly which in turn tossed the drive belts. A top speed of a whoppin' 17 MPH and so top-heavy that you had to slow down to almost nothing to make a turn. Seriously, keep the TS 2.
