Here's a link to a retailer that has some of the best prices:
I personally have a Kyosho Fortune, which sails
decently and can be stowed in the car without de-rigging. The sail handling servo controls both the main and the jib
simultaneously, but is not powerful enough to pull in the sheets
when the sails
are filled. It does best in light air, gusts tend to really make it heel, at which point you lose all steering
authority and it rounds up sharply.
Prices start at around $160 for a boat with this kind of layout, including the radio
. I've always liked the Pro Boat Sanibel, which is well constructed and larger, for around $300.
