Do you have to keep adding duct tape? How long have you been working on it? Do you live where it's dry (I think it would not last too long here in Puget Sound )?
And yes, it's fun!

More pics hey? I'll try to mix it up a little
This is the plug. Took 14 weeks to build. About $1000Aus of auto bog in this baby! Weighs about 200kg
This is 1 of 2 fairing moulds. The 2 go together obviously, with the frame bonded to the floor.
The frame/chassis is a carbon fibre space frame construction. Frame is built in a jig containing all steering geometry, wheelbase and track. All tubes are built in house on a mandrel. Front wheel hubs are drum brakes. Hubs are hand built, taking about 12 hours to manufacture 1 hub. Seat is a bucket, allowing some pretty insane cornering, due to being able to push body agaisn't side of seat to lean weight over inside wheel. Steering is "push-pull". Think of a bobcat steering setup and you're on the money. Chainring is 65 tooth. The complete package minus the fairing weighs in at under 10kgs- about as much as a mid range roadbike
The complete vehicle minus paint. Fairing is Kevlar skin, with carbon (and in later vehicles, fibreglass) "rollcage" monocoqued into fairing skin. Entire fairing is vacumn bagged. With paint and external rollbar, the entire complete vehicle weighs in at 19kg/40lbs
Our vehicle is very fast and our riders very fit, being able to average up to 46km/h over 24hrs of racing through up to 200 vehicles at a given track. On the open road we are even faster, being able to average 60km/h+ (see vid below)
Rollovers are common and quite dramatic in our HPV racing. Here is a pic of our vehicle being pushed over whilst going around a very hairy corner.
Some blood on our side windows. Being fully enclosed and strapped in with a 5-point safety harness doesn't guarantee you won't get injured in a rollover. There are gutters, barriers to smash into and occasionally, 50km/h impacts into bridges .
We are an independent, unsupervised team of 16-23yo males from Australia, who love building these things together. Its trhe most labour intensive and life consuming hobby I can think of, with a vehicle taking 10 months to build from scratch to use basically for one race campaign. We are the most successful HPV team in Australia. Website in sig VVVV

Myself and Rowan riding in a 64km time trial
Me riding my trainer back in the day. Demonstrates the cornering prowness of a tadpole recumbent trike
Footage of our vehicle at the last race we competed in, back in April/May (can't remember)
Hope that's adequate!

that thing is just plain fantastic. I love the idea of the push pull stearing, as other HPV's I have seen have always had the most awkward steering arangement.

Wheelchairman,
Honestly, no BS, THAT is the cooles thing I've ever seen with pedals and wheels. Seriously, I love it! What's the top speed? How well does it do in competition? How hard was the frame construction? Total weight with rider? Drag coefficient? Total cost?
Edit: In my ecitement, I ovelooked the link in your sig

In competition we go pretty well. We have been beaten only twice since debut in 2003, and one of them was in very dodgy circumstances. Our run of results goes something like; 1st, 1st, 1st, 2nd, 1st, 1st, 2nd. We hold lap records at every track we race at and a couple of distance records at times (it's very competitive racing). Here's a race report I wrote on our last 24hr campaign we did, back in March. It's a good read! https://www.bikeforums.net/showthread.php?t=281703
Building a carbon frame is easy, yet extremely time consuming. Some of us have been doing carbon since our mid teens, and actually find it easier then welding, if you'll believe that!
Total weight with rider depends on the rider, but with me in it the entire thing weighs 220lbs/ 100kg (80kg weight plus vehicle)
Drag co. is unknown, yet we had an older vehicle wind tunnel tested for half a day and that is how we developed this shape. Wool tuft tests are also common.
Cost is quite high. $10KAus per vehicle constructed, which includes traveling to the race. We put in 40% of total cost, and sponsers and fundraising efforts pay the rest. We have some very good sponsers, willing to give a unknown sport such as ours a chance.

One thing I have wondered about is that it seems a major problem would be the rider getting overheated without the airflow as on a standard bicycle. Do you still have to work a good draft up through there? Or race on cold days?

AU$10k is not so bad. When you factor in the much lower cost in the US, (for everything) it could probably be almost affordably over 10 months. Where can I get plans? After all, this thing starts at US$10k.

It's the best system I've ever experienced, and I've raced in 6 different vehicles since I was 16. We concerntrate on the upper body only. The legs are fine mostly because they're disturbing air as they rotate.
Hot days are pretty common, with half our races being late spring- mid summer. Hot days are unavoidable, and cold days are much appreaciated . Some races have seen 38*c/100*F days, so our fairing heats up to close to 60*C/140*F. All you can do is rotate riders quickly, or race with a head out design, like this vehicle;
This is "Tru-Blu" which came 3rd in this years Australian International Pedal Prix

Here's a good example.
THis is "Blueshift". They're a fellow competitor and our biggest rival. Sure, their vehicle looks advanced, but it certainly isn't. The fairing is made from coroplast sheeting and their windows from polycarbonate. Their chassis is a cro-mo spaceframe. Total weight is 50lbs. I estimate that this vehicle cost, at the most, $4000Aus to construct. It's simple yet effective. Blueshift just prove you don't need to spend big money to go fast.
Plans? We don't have any on offer I'm afraid. Plans from greenspeed trikes are easy to get though. IMO though, if you want something fast, you have to build it yourself from nothing. Most recumbent trikes manus' design things with the "recumbent rider stereotype" in mind. That is, a big fat old guy with a santa claus beard who rides at walking pace speed with a talking parrot on his shoulder . They can't be pushed to the limits of adheasion that one of ours can. Its a weird issue, and I certainly can't help from over here
As for that link to the velomobile........ no wonder popularity is lacking in this area. That thing is ugly and agricultural. Plus the aero is all wrong and it's typically heavy. If you want a real velomobile then people gotta stop looking at Europe and at Australia instead.
Take Trisled for example. This velomobile came 4th at AIPP. And it's a production trike racing custom rides. Having HPV races over here allows local manufactures to test their designs and ideas to their limits, and this only benifits the customer. You can pick the above machine up for $7000ish Aus. It's aero, its sub 44lbs and it's practical to work on etc.
