ok so new updated canopy with more swoops and curves and whooshes and slants and a whole lot more of a pain in the a$$ to construct ha ha. Let me know what you think about set up number two.

Hi, MoToRNecK. You're making great progress on a solid path to a slipperier AND more cargocious truck. I look forward to v1 completion and test results. Rock on!

I wouldn't be surprised if it serves well enough that you never get around to building that second version up your sleeve.

Looks much better than V1 great job!

Daaaaaaaaaaaaaaaaaaaaaaaaaaaaaaayum DOG!!!! If you fiberglass that, you'll have an amazing aerocap.

The drop in lift coefficient was very noticeable when I had the aerocap on my full size 2000 GMC, the truck felt like it had tail feathers keeping it going straight down the road in winter driving. In slippery conditions at highway speeds, without the cap there were some white knuckle moments here and there, particularly when passing a truck. When I had the aerocap installed, the truck never stepped out even a tiny bit ever.

You NAILED the Template!!! This should minimize the CD achievable with an aerocap!!


Bigger Version of Pic Above

I analyzed the overall angle at about 8° with a final departure angle at 12° So your CL should be at a minimum, at highway speeds, your truck will feel much more planted, and be quieter too.

FANTASTIC WORK!!! Super proud of you!

yeah thanks for the help with the modifications for it Now i just need to glass it and get some plexi glass. I am looking to do some skid plates underneath i just have to figure out where to get some plastic sheeting to do so. but otherwise i am going to just reinforce the canopy structure with some flat bar in certain places and start wrapping it in the next couple days. i do appreciate the help tremendously I figure if im going to put all the work into making this thing might as well get it right the first time!

oh i did have a couple other questions now that you have seen it re shaped the rear end where the tail meets i have about an inch of wood still sticking up from where the curved edges are can i cut that down to bring it level? or should i leave it?

Just a suggestion, home depot sells a product called frp , fiber reinforced panel, same stuff they use to skin RV's nowadays - also used on car wash walls, its thin, its light, and if you use a polyurethane foam under (ie greatstuff) it makes for a near bulletproof composite panel...I've had some good results by tacking down the frp using greatstuff to fill with a 3mil poly backing to keep the inside neat...

With a little heat the frp bends relatively nice too (but watch out - too much heat melts it, and its a royal pain to fix the finish after melting)

I'd say anything to make it smoother and easier to work with at this point, cut it off. You can make a straight cut by screwing a board in place and using it as a straight edge guide so you don't even really have to remove it. I was wondering what that was about. If you leave it or cut it, the difference aero wise isn't significant I'd think.
