AC Boats: R-42 T-Offshore
I didn't take photos during the build process so I can't really post this in the "build" forum. Here is my take on building a fast 8S/10S powered racing catamaran. I use it in T Open and T Offshore heats with both gas and other FE boats.
The hull is the AC Boats R-42 catamaran, which has proven very successful in gas racing over the past five years. This is my second R-42; I sold the first four years ago to another club member who then raced it as a gas boat. Last year AC came out with a full hatch for the R-42, so I ordered another one and built it. Much easier to seal than the original half-hatch, the "offshore" hatch looks a bit odd at first but I am fully used to it now.
Build goals were to make the cat lightweight, fast and crash proof. I concentrated on reducing the weight of this cat, my last Stryker F-41 cat weighed 21 pounds RTR. This R-42 weighs 17 pounds. Running with gas boats on our rough windy Texas water means flips and crashes, and I did not want the packs coming loose and smashing the hatch open. So, motor and packs went between the rails where they can be strapped down. This has proven successful in high speed blowovers - the boat comes in bone dry every time. Handling is superb, and the AC hull is very strong and lightweight. Speeds are well into the 60s, propped however I need it to be for the course and conditions. Speeds over 65 are seldom needed nor safe....see the video below.
Components:
Neu 2215/2Y
Schulze 40-160
10S1P Hyperion 35C/6500 mAh
HiTec HS-5765 servo
5-cell 1600 mAh NiNH receiver pack (to be replaced with 2S LiPo for more servo torque)
Octura x457/3 and x462 props (among others)
