So you all saw the spectactular failure of my "tuned" (
) Mustang and Camaro.

What went wrong?

Adrian Norman of Scalextric knows, but do you?

I will know better next time but given that I did what I did why did it all end in tears when in theory it should have been glory?

Can any of you "out Adrian" Adrian?

Just to give folk more info I had one standard Trans Am bar magnet in each car, Slot.It wheels, gears and axles (one car having a Scalextric pinion but that did not fail), Slot.It 25k and 29k motors, pro-Slot rear tyres glued on, Ninco guides and braides, and the front tyres had been sanded down using an electric drill to the extent that the cars effectively were running as tri-pods.

They worked fine on my SPORT track where the tuning took place.

Why did they come last or fail to finish at Phoenix?

The cars are running OK at home. I was thinking that a 50% power increase to 21 volts would give them more grunt at Phoenix and they seemed to lack grunt or anything in fact! The answer is not poor running gear or gear meshing. Why don't I bring the pair of cars up to Wrexham where you can look at them more closely?

So you pair haven't "out Adrian" yet with your answers. It is a factor I failed to take into account but Adrian spotted it straight away!

You can have pictures of the chassis on the 2 cars tonight to give this thread some clarity. Jon said that Phoenix would be running 21 volts on the day in the senior magnet event so I anticipated that sort of power boost. What I should have done is popped over on the Saturday to practice and set the cars up for the circuit conditions but notwithstanding that there are 2 things that Adrian spotted during that day and pointed out that I simply did not anticipate.

There is one significant difference between the chassis of the Trans Am cars and the chassis of the MG Lola and the efforts and adjustments that Scaley make in pre-production to get cars running as they want them to run straight out of the box astounds me. The significant difference refered to above combined with the other issue that Adrian spotted doomed my 2 cars basically!

I have taken a few chassis pictures to post but I have put some Phoenix pictures on tonight instead. There is probably enough photographic material to entertain us for the next week or two.

Adrian did not actually suggest to strip out the Slot.It gear and put back the Scaley gear so anybody who has that idea would not be right!

What he did say though was that there is a genious at his Viking Club who can make any Scaley car perform as well as a Slot.It car with standard Scaley bits.

There was a reference to the track. It can be difficult to set up a magnet car on SPORT track and then blindly go racing on a Ninco circuit. Adrian with his experiance hinted at why.

There was another reference to the magnet position in the Trans Am relative to that in the MG Lola. That is inevitably going to make the MG Lola the better performer on Ninco track if you tune your cars for optimum performance on SPORT track. Scaley apparently do some pretty amazing things to their cars to get the magnet positions just right for optimum performance on all track types. Adrian implied that one of my big mistakes was to lower the chassis on the Trans Am if I was running the car on Ninco track.

Hornby spend lots of dosh to get it perfect and then folk start messing it all up. Like me!

It must make the boys and girls at Scalextric weep!

Anyway, I have not been too specific with my clues but there are two very clear factors that I did not consider that no one has touched apon yet.

I will spill the beans eventually.

The advice was not a case of what to do. Adrian will never tell you what you should do (unlike me!
). He simply advised on what I should be looking out for and taking those factors into account, which I didn't/hadn't. That is down to my inexperience with tuning cars for Ninco track. But I have learnt a lesson so thank you Adrian for your words of wisdom (which maybe I should keep to myself to give me a head start next time!
)

The basic ideas that I had were sound so it would not be accurate to suggest that my tuning set up was flawed. It was more a case of the set up not being suitable for the environment. Next time it will be!


Now bearing in mind that the cars are good on SPORT track it will be interesting to test them at Wrexham if you have "the power" Inte!
