CRX HF reverse trike project

[groundflyer]

Well the back is now set Used a 8" c purlin fit perfect strong now can pick up back with the sheet metal.. with no twist. Also got the seats mounted and used the crx seat tracks I don't think they are made to come of the orignal seats but that did. Sorry the pics look bad but there ya go tight fit also

As for the Dome has a 8' riser wall in lower section that a 7' riser and in the back bed abd bath a 6' riser Has 28 windows all together

As for the Polymetal got a sample yesterday I like it..

Groundflyer, have you had a chance to testdrive your CRX-trike yet?
It looks like you will get a nice shape to that body!

[groundflyer]

Nope have not driven it yet.. Want to get welded and then get running in the field and stoping right. Found a nice low profile fiberglass front end I wanting.

But will see how that works

Reminds me of a project I built a few years ago :-)

That gas tank should take you about 1,000 miles or so

Well the time has come for the rear lower pan.So is this a big rear diffuser?

As for the wheel fair That will be part of it Hell it would look neat.
And the angle of the 3/D fair starts at the breaking point of the body?
or can it go straight .

Yes I still see a few treads out in web space on it did you erase the youtube short vid of pic cant find it Did you get much better power and fe with that mod. Or was that just for fun?

[todayican]

havent eve thought about the crx for a while if the vid is down, I diddnt do it :-(
I never measured the FE (it was before my hypermiling days) But it did seem faster :-)

Angle your "horizontal" flat piece up at the back, from bottom of car seats to about 2/3rds up the back of the tire. Approx 12*?

Then for the bike, 'channel' out about 1' wide, and build vertical walls down. The idea is to flow the air smoothly under the back end, while channeling air around the tire that sticks out.

Not quite sure on the exact angles and all that, perhaps a quick chat with Aerohead or someone along those lines will be able to fill in the details.

Basically, I was saying in that first pic, the floor should angle up towards the rear, like a big flat diffuser type. But as shown in the second pic, you'll have to 'notch' out a place for the rear wheel. The idea is to smooth all that out as aero as possible. Look at the Aptera and others, you'll see the direction I am talking about.

Great to see progress on this! Can't wait to see it finished, and some YouTube vids.

Here's the point in the design process where Elio Motors went from a semi-enclosed to enclosed rear wheel:


I'm not sure which I prefer. A convex bubble on the back might be necessary to fit across the back of the tire.

Are you going to go with Polymetal?
