Being new to the forum, I wasn't sure of the "vibe" around here. Not sure how my questions/comments would be received. I posted just because my own experience/memories were triggered and it was a great time for my RC boating journey. You're spot on with the history of the sport/hobby and the newer boaters. This is a great hobby, both for the journey and learning and probably most importantly the fellowship within.
The early Crapshooters were nuclear fast, I mean fast compared to Wing Ding's and other stuff. I saw an article or ad in an RC magazine about the Gen I Crapshooter and they guaranteed 70 MPH with a 40 engine - when I contacted Precision Boats, Tim Reis answered the phone. He said the boat could handle a 60 as well. So, I ordered one and put an early OPS 60 in it. Wild times with that combination. There were several consultation phone calls with Dennis and Tim. My buddy built one too. We couldn't get the boats to turn. After thinking about it, the early Gen I/II kits came with running hardware - strut tube and rudder assembly. A tapered aluminum wedge.
Seems like back then, the guys in Michigan were running straight pipes on the boats which would explain how the Gen I hulls could handle the 60 power. I didn't know enough yet to simply move the RH sponson out to compensate for the torque problem. Learned that later from Don Pinckert's wife (Talking to Don about it later, he said she really wasn't supposed to let that get out) when setting up a Tundergator twin.
On a call, Tim told me to pull throttle, set the boat with some rudder and throw the throttle wide open to "wheel it through the turn" on the prop. That worked well with 1 boat on the water, not so much in traffic.
Tinkering with the Gen 1 Crapshooter the best combination I came up with was an OPS 40 with a Super Tigre G-40 rod that was if I recall 0.150" shorter than the OPS 4 rod. Turned the case to drop the sleeve and retain stock timing. Opened the head up slightly from stock for 40% nitro. Trimmed the front sponsons down 1/4" overall and resheeted the bottom planks. Larger turn fin and larger Octura wedge rudder.
That boat would have done some damage in heat racing when I was in California at the time. Around 76/77 I went to a race in Monterrey and was doing some test laps in the morning pre-race time. Throttle servo hung open, (loose motor mount screw wedged in the gears) so when I got on the rudder, it took a nose dive and stuck in the bottom of the pond. Was 4-5' deep in that spot at the entry to turn 1. After about 1/2 hour, the guys running the retrieve boat were circling around the area it disappeared and saw oil spots on the water, probed around with a paddle and it popped up. Engine was totally destroyed, boat had stress fractures as well. That combination used to pull a full Octura 1465 prop without any bogging. Never rebuilt that boat and engine combination. Had moved on to the 60's class.
The mid 70's Crapshooters were boats that you had to "turn down" a little as they were very fast in the era. I would guess by the time this kit/boat were designed they had evolved the design past all that into something that was a better handling boat.
