There was some discussion of .45 twins going on in this thread starting at post #29 http://www.intlwaters.com/index.php?showtopic=53461&st=15&do=findComment&comment=501952
I've not seen one that was very impressive yet. But, I've thought about building a Multi-Engine, and I've got 2 Novarossi .46's that I've been tooling around the idea with for a while.
I have some questions about design that could make or break this project.
(1) How best to cope with the weight disparity 11 lb vs 16 lb? The race water will be choppy, will making the boat larger than needed be beneficial? Lets say I can get everything balanced out in a 40" boat, should I still go with a 45" boat? larger? Of course it will be a struggle to keep props hooked up, but other than that does size matter?
(2) Countering Prop torque. I'm going the traditional twin engine/ twin props/Normal rotation. What is the best way to keep torque steer down, or counter act it? Rudder size, COG bias, biased lift, and biased downforce considered. I've been following the SAW mono topic for a while, and have learned a lot from Andy Brown and John Finch's back and forth. Thanks Guys!!!
I'm going to try and start laying things out soon, so If any guru's would please comment here, it would be awesome!
