Just picked up my 312 Fastech two weeks ago and the boat
came with Bennet trim taps. For my winter project I want to
up grade to K-Planes. What model number should I go with?
280S or 380S? What model number K-Planes came with the 312 from Formula when it was offered as an option?

Thanks

Just sold my 312....it had the 280's. The 380's wouyld be overkill.
BTW: I might have a line on a used set of 280's. More to come if it works out.

280s....a good friend has one...Check with Fred at Trick for tabs. He has some very nice ones.
