BECs and full bodies
Mulling the idea of a BEC, given that locosts in general are pretty rough and rugged for frequent use, so the thing would likely mainly be seen at the
track.
My question is, how does the BEC concept stack up relative to the extra weight of a full body? Given that I can't afford carbonfiber, I'd
expect the glass bits for a body like a Fury to weigh a couple hundred pounds. Throw in some decent rollover and impact protection and perhaps a more
torquey CEC would be a better bet. What do you folks think?

I don't think it weight ~200lbs as thats nigh on 100Kg.
My R1 Fury is in the region of 430 to 450Kg which is not a great deal more than the Striker its based on.
Also what you loose in a bit of extra bodywork weight I think you gain over say 80 or 100mph in terms of aerodynamics.
There are several different thicknesses of bodywork you can get though and I think mine is only one up from the thinnest which is only recommended for
race cars (you can see light through it almost!).
Rollover gear is going to weigh pretty much the same irrespective of sevenesque body or a full body.

Actually I stand to be corrected on the total weight of all the glass as:
a) I didn't build it
and
b) I seem to recall the weight saving on going for lightweight bodywork to be like 20Kg or something!!!
I could well be talking out of my backside therefore.
But in general terms I wouldn't rule out a BEC Fury because you think its performance will be stifled by the weight of the extra fibreglass.
Mine still shifts plenty good

My BEC track day toy...
Without the engine I can lift the front of the car off the ground with one hand...and im built like a stick insect!
Will have a ZX9R engine in it in a couple of months...

Aren't a large number of the RGB racers bodied?
i.e. There aren't many 7-a-likes on the grid.
The aero benefits must outweigh the downside of carrying the extra fibreglass.
Remember you add weight with the full body, but you can take off the weight of the bodywork (not much, but some) of the 7-a-like.
Go for it!

IMHO - that;s the attraction and the reason I drive them and cars like them (Elise). You get 100% feedback from the car.
I do find it strange that I dont care about rattles, bangs etc in the kitcar/Elise, but the slightest rattle in the BMW drives me mad!!! It's
insane! 
You'll be surprised at just how little difference there is in weight between the 7 bodywork and the full bodywork. If you get 'dry
laid' fibreglass (like Lotus do) the bodywork is unbelievably light - a whole front clamshell on an elise weighs the same as my 7 bonnet...
Plus, as hobbsy said - the aerodynamic gains are massive - a 7 is about as aerodynamic as a shopping trolley

If you believe you're not crazy, whilst everybody is telling you, you are - then they are definitely wrong!

If you look at the RGB (road going bike-engineed) race series many more people use the Fury shape cars than the Locost type cars.....

I need some of that bodywork! That would take me to 200 - 220mph top end!!

Wow, many and bang-on responses
In the colonies we hardly ever see full-boddied BECs except for in a spec series or two. It also occurs to me that although I do pretty fiberglass in
the boats that I've built, nobody's ever accused me of building particularly lightly Do any of the UK builders use vaccum bagging in
their construction?

Most bodywork is wet laid CSM.

the fury bodywork weighs 40kg plus 7kg for the windscreen for the standard weight. the race weight with aeroscreen is nearer 30-35kg

I'll have you know that only 4,276 people have ever accused me of being pedantic!
On a more serious note - I far prefer the appearance of full body work over the 7 types and was looking at something like the Spire GT-R (development
of the MK GT1). Having also been involved with motorsport of various types over the years, the only thing that put me off was that there are fewer and
bigger pieces of fibreglass for me to replace if I have a run-in with the armco or tyre wall! If I had more faith I would have gone for a full body
option.
