The TP is the best motor by far.,you can re angle the motor mount to keep the motor under the lid. The brass tube for the flex will just need a S shape. I’ve used those fins they are good. A straight fin is all you need to corner fairly good with not costing speed.
I've done what you plan to do with the flycolor 90esc and it works great, though I made my own cooling plate. However your weight measurement is slightly off, you will have to use zip ties or some other method to attach the cooling plate to the esc which is more weight. It's not much but since you are comparing you need the correct weight. Yeah I know it's being picky. But I've had no cooling problems.
Okay I'm trying to follow your lead and I need to know the amount for the term Finn I will assume that you hand me that yourself probably out of a piece of carbon fiber I'm going to go ahead and order the tournament out of China just like you did if you take a look at big beast boat didn't he take and run two turn fence one on each side now I realize that we're going to be going straight and to the right. So I don't know what two turn fans is going to end up gaining probably won't turn well to either direction. So what my funny story for you is I ordered my rigger with the full hardware package just so that I can get some linkages rubber boots a few other odds and ends that I didn't want to have to piss me off I just wanted them there. If you notice in the package I even got a water strainer but basically it's a fuel filter I don't know what the heck that's for but there's more funny equipment in here like the servo that they provided I don't know what they're expecting you to do with the like 2 oz and then their choice of OutRunner motor I swear the OutRunner motor is no bigger than my some or maybe it's as large as a thimble it's the cutest little thing I've ever seen and they provided a shark 40 amp with it. Needless to say so far I've only gotten half of the hull together. I keep putting RU-vid videos of folks that have made and or are running the shrimp outrigger and I keep losing time. I'd like to know what you ended up doing for the paint job I see that you painted the sponsors but I would like some more info on painting
I want one so badly!! I have always wanted to build one!! One day when I save up I will try my hand at building one! They look like so much fun!! #BGFL
