Video with newer paintjob

i like the theme These are older photos/paint job, will have to dig for some newer ones

How much kissin' up to our wives does it take to pile all this money into these things? Just the other day I was getting rolled eyes from the wife about the CMB I want to buy :lol:

just an offbeat thought- some airplane aerofoils have AOA stall points, I wonder if something similar could be designed into a tunnel?

aeromarine research says: LA = [½ ρAV2 SA CLA] where: LA = air lift ρA = density of air V = velocity SA = surface area CLA = lift coefficient man I havent seen equations like this since highschool! anyone got a slide rule? :lol: Did anyone see the National Geographic documentary on...

I've been starting a winter time boat project in cad, was curious if anyone ever tried a tunnel design with a further rearward aerodynamic center? By moving the lift back would it be less sensitive to blowovers? The AOA of the foil at approximate plane is just 3 to 4 degrees, as well as a...

I definitely like the idea of adding some form of aerodynamic control into the mix. Regarding r/c boat design and innovations has anyone noticed the rather small amount of plans available on the web? There are a few from rcboatmodeler, and a few here and there, however the number available is...
