Looks like a lot more time and effort has gone into your build Terry. Bet it's a smooth runner.

Also, I've been trolling 'the bay' for a Ligier and other early Scaley F1's that have a chassis.
This has been a good resource for me to see what F1's they came up with in that era. http://www.scalextri...Ligier_JS11.htm

I love the independent fronts Terry. Very clever. I'd be keen to see more detail of how you cut the pod into the chassis too.

I have had a crack at most (all?) of the available options from this era and have worked up the Ligiers. They run well but don't seem to as nimble as the Renaults, 312Ts or the Brabhams or Williams.

The Williams (front and centre in this pic) often come up cheaply on the Bay because most have a broken front wing. Scratching up a replacement is easy but if you score one complete I would epoxy a support layer under the original to be safe.

The Renaults' pod came from a older Ninco car which I had here in bits, mounting the motor in a secure position is one of the more critical parts of the build and one which can cause the most head scratching.

This is my 2nd renault, the 1st one was traded to a fellow club member who didn't have a lot of experience in building, that car now often knocks me off on race nights!

most of my F1 builds incorporates independent fronts, I think it contributes to a smoother car,

Testing so far shows the Ligier to be as quick as the Renault, but the work to get the Ligier has been more extensive than the Renault, I just love the mean arsed look of the car!

My Lotus has a different body/chassis, the motor and axles are attached to the upper body and it has a lower pan screwed to it, any tips on improving this set up? I'll tube the front axle and probably replace the guide.

I've a few of those Lotus bodies( is it Lotii?) and for now I've put them into the too hard box,

The Ligier is just about done but I'm still not happy on the motor mount, been trying to avoid gluing the motor in but it may be the only solution.

The motor has 2 motor screws holding it in place but I'm still getting a bit of movement, maybe I should do a pic to better explain, the hot wax gun awaits!

That's interesting, seems like a step backwards on that one. An earlier Brabham I've got has the same layout minus the underpan.
They weren't thinking anyone would be wanting to add float into it.

Its weird that scale went down that path of putting the motor and rear axle set up into the upper section, I know Oldslot has done 1 and its quite quick, but his chassis is a more conventional adaptation.

still, with a set of Ultragrips and some lead on the pan it might go as well if not better than the modern Scaley F1's.
They pretty much have to run tight and there isn't much room to add ballast.

I've been thinking about getting a Scaley Ferrari 643 for ages now so I'll have to have a closer look to see if they have the same mounting system

I've tubed the front axle, put smaller diameter tyres on, Ultra grips on the rear ???? on the front, lowered it and fitted a better guide and its a lot quicker, oh and some lead up front.

The 643 chassis is the traditional chassis style - easy to work on. I've never had real success with that F1 style though. The Brabhams / Renaults are a half a second faster on my track.

Have you tried Pauls XPG F1 tyres?

All my F1 cars have them, they last, stay well gripped throughout and are easy to true.

I have a 4 of these Indycars I am working into a house class for a 2 or 3 hour race on a club night later this year. They're often cheap as chips on the auction sites.

Posted Image

I've kept the stock guide. The body pivots off a screw forward of the guide and a male / female slot at the rear of the chassis. The male part has been filed down to get some body rock.

Posted Image

Interestingly, i tested the car this morning before I braced the rear end with piano wire. The bracing not only smoothed the car considerably it dropped the lap times by 0.4s.

You can even shoehorn a Mabuchi into the Tyrrell Elf with some dremel action and JB Weld. It's chassis is like Aquakiwi's Lotus above where the running gear is fixed to the body not the chassis so there is a bit more work to do.

Posted Image

Space is limited but bracing the rear is a must.

Posted Image

This car was released with the Johnson motor but a Mabuchi fits if you widen the motor cavity and get the Mabuchi as low as possible. You'll need to dremel out some material from inside body above the motor as well.

Posted Image

This car laps my 95' track under 7s when pushed and is another stable, predictable car.
