Body work patterns done, ready for composite molding. The TUB is contemplated to be mostly monocoque construction with steel hard points.


...

My 2 cents is that if you cant install a known formula race engine the next best fit would be a hi performance bike engine conversion. Hi revving, sound and perform, great, come with a six speed...

G'day Guys, I suspect, due to me tidying up my Apex Speed profile, I may have caused some of the earlier images in this thread to vanish!

So for anyone who is interested in those pics here is a...

Hi All,
Is there a reason why earlier pics uploaded to this thread are no longer visible?

I thought It may be my browser but seems not.

G'day guys, pattern work on the body continues. Ive just completed the basic shape of the RHS side pod. LHS next.
I'm still yet to add all the corner radii. I'll do this last.
The side pods are...

We had a local air show here on the weekend so as a part of my display I put the car project out for viewing. I managed to get the center section of the body work pattern looking half decent in...

Hey guys, bit of an update on my FB/F1 project. I've decided to shift focus from the rear of the car and now to the front, which will entail the body work this will help determine the boundaries...

Hey Russ,
The plan is to make a composite molded plenum chamber perhaps in carbon or not but composite just the same. This will have 4 ports for the Busa throttle bodies to attach. This plenum...

Gday guys, Well after doing a little of research I decided to bite the bullet on a cheap Ebay turbo. $185 !
All reports are they work suprisingly well. Surprisingly :) We'll see.

I've made the...

Yes BOTH, clear the lower wishbone and tension the chain.

I agree, double shear would be optimal, but in this case that’s not so convenient. The cantilever set up here is pretty stout and the...

Gday guys made the chain tensioner today, has a jack screw arrangement, still have to add a cross member with some bracing for stiffening.

will it work? Comments...

I used bike shocks and fabricated the rockers from plate steel. The bearings are 1" bore and two are inserted one each end against a bored shoulder. They were not difficult to make. Now whether...

Oh I made a silly update video, this was just prior to the making of the damper bridge cradles.

G'day Guys,
Been chipping away at this project, some progress has been made. Rear of car being the main focus, most parts are designed in CAD then over to the machines to profile or turn the...

Yes thats right, here at my work, Rotec, we fabricate lots of engine mounts so as our engines may adapt to any appropriate aircraft in the HP range.

We have a welding jig that we can adjust for...

Yes I'm hearing you about the head mount!
Ok Ive got just the ticket, we use large rubber Lord mounts on our radial engine mount corners. One each side will addapt nicely. I recently changed the...

Nice work my man! You raise a high bar.

In my case the frame looks a little sparse right now but as I said all the bracing, diagonals and cross members will go in once the main stuff in set in...

Hi All,
Ive been making some progress. This build is 1980's inspired F1 look alike. A bit of fun.

Hayabusa power. Bike shocks and bike brakes.

Ive drawn the basic thing in CAD. I have a...

Hey John,
Yes I watched your work, I could see the diff issues. I think Ive solved some of them with my diff design. I'll post shortly.

Ive build a few home built aircraft. Yes it seems like...

I have a Hayabusa Gen2 1340cc. That should do it :)

Yes I get you John, But I like things be just so. I managed to find some decent center lock rims. Ive made my own centers which look spot on period 80's Fondmetal (ish). Im happy now.

I agree...

Hey Guys,
Im still at it, Recently finished machining what I think is a nice LSD set up. This set up sees the sprocket outside of the rear chassis structure and inline with the engines sprocket...

Yeah I agree there must be some form of spacer the slides over the drive dowels and is just thick enough to imbed the hex sextion
of the drive dowels the wheel rim face would then be able to make...

Well for sure the wheel where it mates would have a flat face. Thats fairly typical.

But as its pictured the wheels that I have would slide onto the 4 drive lugs no problem but when the center...

Gday guys, as I research my upright, and brake / spindle design I came across this photo of the Ludemann build. As I look at his assembly I have to assume that the wheels inner boss face seats on...

Thanks for sharing, great pics! If you had an upload link I'd love to down load higher res versions of all the pics you just posted.

As Im in a structural design phase ATM.

Im curious as to...

I find with most endeavors one can dream and plan for ever. Some times all you need to get rolling is to just take a the first step. So with that, yesterday I hit the junk yard and raided some...

It may be just me, but once I learned how to make decent FRP molds I never looked back, started with large RC models then morphed into kit airplane building. And now, with some luck, building a race...

Also being a pilot and having built several home built aircraft myself and sold countless aircraft engines to those attempting to do the same, I can say with certainty that around 90% or more...

Thanks Glen I'll send you a PM about the engine, my research also uncovered the best Hayabusa units are indeed post 2007.

G'day Steve,
Bearhawk are the booth right across the road from me at EAA Oshkosh. Nice guys, we often talk about fitting the larger R3600 radial to their smaller machine. Our geared radials punch...

We have done the Wittman Tailwand before, we have the engine mount and oil tanks, goes great. Hahaha Jesus you'd think I was here to sell stuff which I can assure you im certainly not.

Very...

Hi Steve,

Airplanes First: Very good to hear you're building your own plane, such a great endeavor and to then test fly your creation is something very few can say they have done. To me it was...

Hi All,
First off, I'm very impressed with this forum!

A quick intro,
My name is Paul Chernikeeff. I'm the founder and owner of Rotec Aerosport Australia. 20 years manufacturing small...
