I'm about to start working on the figures; I'll not be over populating the track, just a few spectators, officials and mechanics all suitably clothed in period 'weathered' garments and overalls (this is Britain after all). I'm also making a small number of public address system loudspeakers to be positioned around the track perimeter (unfortunately they'll not be fully functional, but will hopefully look the part).
I'll continue posting a few photos as the circuit busily prepares itself for the big event.
I suppose that the answer to the following might be... "Just build it and you'll find out this fall".
However...I was wondering now that I'm to the stage where I've put a motor and gears in my car but don't have the ability or facility to test it on anything near the size of the Southend track (I only have a 27' Ninco track-- my 65' painted Ninco set has been in the boxes as I have no place to put the larger track)
My car has a relatively low revving FF050 motor - about 15.5K at 12V. I could put in a higher revving motor as I have other FF050 motors at 18.5K, 22K and even that frightening black cased 30K motor. But I am a bit leery of that much powerin a light car especially as most of these motors have mediocre brakes and my car won't weigh more than 60 grams. At least that's the way it is built right now.
The gearing is currently at 9:23 which is okay for smaller twisty tracks. I'm wondering if it would be wise (or foolish as the case may be) to up the horsepower and/or change the gearing given the length of the Southend track?.

Teams and drivers can rest assured the proprietors of Forest Hall Circuit have ensured the very latest state of the art safety technology has been installed to protect the safety of everyone competing in the forthcoming Grand Prix.
St Johns Ambulance staff and the local fire brigade have recently been taking part in a number of training exercises to ensure drivers will be taken care of in every eventuality.
Further updates on the circuits preparation will be posted as and when confirmed.
If ambulance only is required we are all in good shape thanks to Dave's careful planning.
If a fire breaks out I suspect there will be bigger problems than saving our cars...
Note: It's Ten weeks and a day till the due date in England, and for those of you from far away, please allow adequate time for mailing--one week from US, two weeks from Canada.. four weeks from Australia. Actually I think mail service is bit faster from down under but I know poor Nigel has experienced some delays that were ungodly. So plan accordingly.
Last year my Eagle entry achieved some notoriety by exhibiting significant top end and no brakes whatsoever. Since it will almost certainly be a repeat entry, I thought some investigation was in order.
When I tried the usual test - hold the back end up and apply and then release the throttle, it responded in an exemplary fashion, with the rear wheels stopping instantly. A brief track test, however, bore ample witness to last year's issue - brake application was followed by a gradual coasting to an eventual stop. Obviously what little brake force is available is sufficient to stop the rotation of the light wheel/tire combination but is overwhelmed by the moving mass of the running car
A smaller pinion is clearly in order - I think its running an 11:32 now and, on the off chance that the magnets have gone south, a new "Taiwan Mystery Motor" (ex All Electronics) will be fitted.
I'll also try to patch up some of the battle scars - time permitting.
Good day All !!,..........I am hoping to make the deadline for this years event, but, I find building time hard to come by in the summer, so it will be nip and tuck......Mark, ....this is why I have not reserved a number......I will happily take what is available at the time.
Anyway, I thought I would post progress to date......
I have managed to cobble together a chassis, and build up a wheel/tire package.
I was initially going to use a modified Mashima train motor, as it appears to have plenty of grunt, and is very tiny, but not having a ton of experience with them, I am not sure of its longevity, especially with rewound arms. I will continue to test a few various arm winds , and if in doubt I will install a stock Scaley FF050, which, I believe will be more than enough.
The upper front control arms will be attached to the body (see body pic.), and I have yet to figure out what the hell to do for a rear end suspension. (Mr. Sheldon sent me some lovely machined rear shocks which I am dying to use)
I will be using a MRRC Matra shell, and while the body looks quite good, although a little wide, the stock motor/transmission is HUGE . Time will dictate whether I will be able to graft on something a little better looking.
I will manage to remove the existing driver/head, and add a few detail touches.
In this pic. you can see the upper susp. arms wiil be attached to the shell.
With any luck, Mr. Beltoise (number TBA) will see you on the track this fall.
Cheers Chris Walker
PS Please forgive me if these pics. are too big...having an issue with Photobucket.........please feel free to resize.

I agree Mark, the M7A in its slim form without the extra fuel tanks is a beautifully clean, simple and functional design although I have built the Spanish Grand Prix version with the pair of separate pannier fuel tanks in the past for another event.
The Charlie Fitzpatrick "Classic"shell is excellent but I will have to add the engine cover that Bruce and Denny used at Spa.
