OK, two possible solutions - after some feedback from you guys...

I'd vote for the second option. Looks less fussy to my eye, and can't obscure vision to the mirror (might just be the angle it's
rendered) or the front wheel (nice to see exactly where you are putting it.

Second option me definately. I laid out the basics of a midi design in CAD and came up against all the same problems as you. I had to get rid of the
files as it was driving me mad. I really admire the work you have done so far.
I can't photoshop it but I quite like removing the top rail as your second picture, replacing it with the bracing as you have from the scuttle
back down to the mid (or new top rail) AND similar bracing from the rear down to the mid (or new top rail) at around a 45deg angle. To me it looks
better with the extra triangle.
I quit the idea of making my own middy because it took me a year to decide between a +4 and a +442 Locost and I realised I would never build a thing
at my rate of descision making.
I am following your progress (and JC's) with immense interest, I wish I had the bottle to go for it as you have. I think your car is fantastic.

thanks both of you
I prefer different soluctions depending on the angle viewed, I'll play around with a few more ideas.
Mansfied, i'll give your idea a spin later, just have to avoid introducing the problem again, as anything there is instantly close to the
head

James,
I haven't kept up with your thread in a while but did my usual backwards reading of it today. It is great to see the progress and the
suggestions at each stage in your design process. Brings the best out in everyone! The result so far is a great looking and a promising solution to
an original build... keep it goin'!
I wish you had picked up the moon rover just once so we could see its' camparable size. Pushing the barrel up the hill was the only time that a
perspective of size could be judged.
I'm sending the clip to my son in California who is an active DP (Director od Photography), thought perhaps he would be interested in its use in
filming from angles and environments not suitable for current rails, slides or other contraptions.
Now if you can only make the little monster clean up the junk in your yard.... you'd really have something! ![](/images//smilies/bigsmile.gif)
Kidding, of course!

I'ms sorry James that was a bit of a curve ball but wasn't meant to be.
I was refering to the link you posted on page 5 of this thread and the video of the RC car. That's what i get for reading things backwords.
The first intallments are thought of as the most recent and sometimes I forget that what is news to me is old news to those who do things more
conventionally.

I hope this makes sense to you now.

ah right with you now. It was way too big and heavy for the usages I require - so it's currently being scaled down. Going back to tracked drive
to allow it to use stairs...

Put the tank behind the seats, there's plenty of space (so it could be bigger), it's safer, AND it improves weight distribution.

as regards the tank, it fits well where it is, and would be great for a logo, (see latest renders) - any comments on whether this is safe
'enough'

Designwise I prefer the first option, although as other have pointed out, the second option is much more practical.

Love it!
Really fresh concept, that front end looks spot on IMO and I think using panels here and there as needed rather than hiding everything in a jelly
mould is a very good idea.
I'm a beliver in form follows function so I tried extending the tubes in the second render so they run right back to the roll hoop, which should
make the chassis stiffer and probably a bit stronger.
Also added another diagonal bracing the roll hoop. Is it a bit too functional??
Fuel tank in the space behind the seats seems logical to me too - keeps it low and central, and in the part of the car which is best protected in a
crash - at lleast you'd hope so if you're going to be strapped in there!
Someone mentioned fitting exhausts in. If space is a problem, they could be run forwards between the seats in a very narrow 'tunnel', which
needn't be structural - just folded ali sheet for example. Then exit at the front somewhere, may help with fitting in silencers as well. Its
worked pretty well that way on my middy project - see pics.
Not sure how that would work if you had tank behind the seats as well though.
Anyway, just some ideas to add to the pot, keep up the good work!

I quite like the straight tubes actually, they echo the tube below nicely, I also like the extra bracing on the roll hoop.
have actually welded the roll hoop to the chassis at the weekend, but found despite many measurements sitting in the car - I just dont feel it's
high enough to be safe without having a very laid back driving position. Trouble is as soon as I put even just the 8cm rise I calculate will make it
safe, it destroys the proportions entirely
I will produce some more updated renders with the revised roll hoop tonight, you guys are always great for fresh idea's

OK easier to just photoshop the change on, here's it with the revised height. Those rear braces certainly help to avoid it looking like an after
thought towering above the chassis.
But it still look a lot less sleek than I'd hoped for. Obviously this is a fixed measurement - any ideas where i might be able to rescale to
reduce the apparent height?

Hmmm, the high-hoop is definitely less sexy looking, but safety is more important than looks, I guess.
I still like this look best though, it gives a really nice look to the car:
Perhaps you cold try something like that again? With the higher rollbar you just might have enough headroom..
I guess that would make it more similar to this:
Idunno... it may make things easier if you'd ever decide to fit weather gear ![](/images//smilies/tongue.gif)

truth is none of these designs appeal to me like the original one with the complete curves did - it's just starting to look boxy like the first
one did again. Might revert to this design and try and again find a solution to the head + visibility problem...

You're right. Visibility in many directions is a huuge issue with your best looking design, even if you can solve the head against the steel
tube problem the visibility problem will not go away...

I feel your pain.
Go back to the beginning keep what you liked ditch the rest and keep going until you get something that works.
And remember whatever you make will be better looking than the thing below

I went through the same thing on the GTT and ended up raising it around 80mm higher than I planned as safety overuled looks.

Cool Design
James,
your original design is cool but the progressive edits are moving further from what you wanted and closer to many designs that have already been used
- Atom etc. etc.
Keeping the reclined seating, are you able to scale up the design slightly and raise the offending top rail and incorporate it as a roof line? Maybe
use gullwing doors or Nova styled front hinged roof. You could then keep the original proportions.
regards
Steve

Working long hours at the moment, so not much progress - but I finally got the correct fuel parts, so I gave the engine a good thrashing. Gives me
some inspiration to keep going!

With some inspiration I saw on MK engineerings site for a roll bar, I think i've cracked the issue with making a roll bar that's tall
enough for safety that also doesn't make it look overly tall
I see you've been working your magic again in the MEV thread Fuoriserie - feel free to experiment on mine too!
Thoughts?
Oh and also - I know you all like videos here's that engine run up from last weekend. Don't worry the engine was up to temp and I was just
checking the rev limiter...
