NSR GT40 Mk 2

Recommended Posts

Hi folk,

wow, have I hit the deck running - seven cars lined up on my workbench all demanding they get closer to completion.. and another three to come - what have I done?

Whilst we were up north, I ordered an NSR GT40 mk 2... I am very impressed with NSR models, and I expect there will be more to come... 

I had a good look at how it was set up ex factory, and something just wasn't right - I could not get module/chassis float when the chassis was fitted to the body, but it was fine on the bench minus body.

I took a very close look for anything which may have been fouling - and sadly, NSR have made the exact same mistake that I suffered with all my Slot-It GT40's... that blasted plastic engine and intake manifold - it fouls the motor pod..

As you can see in the pic above, the tab melt method of fitting components did not allow much room to decrease the depth of the plastic engine/intake... 

There certainly wasn't enough clearance to be gained by simply chomping into the body of it... so, my plan was to remove it and do some trimming - then fit it further up into the body...

 

Another area which needed attention was the power leads to the motor - they were first point of contact between the pod and the body.... I de-soldered and re-fitted them so that the leads and terminal were not proud of the motor body...

We can see in the pic below, that the factory placement sits very low in the body - and this fouls the chassis motor and pod...

In the pic below, we can see that I have attacked the plastic severely, just barely avoiding breaking through to what will be visible through the rear window of the model.

I have also cut away the front mount and opted to fit it flush with the body cowl, rather than have it mounted underneath - this combination gave me sufficient clearance for the motor and pod to float within the adjustment I have set this model up with...

So, here we have the side-one pic with motor fitted... and if you compare the first pic to this one - you'll note that a considerable amount of adding clearance needed to be emplaced...

So, with a bit of work adjusting float and truing in the tyres... this model is pretty much good to go - it did need a bit of work but I believe it will be one of the best performing GT-40's that I have... the bottom dwellers are the two Scalextric ones I purchased when I re-entered the hobby seven or eight years back... what was I thinking - a second hand "mint" GT-40 I "won" at auction... and paid $85 delivered from W.A....... Scalextric - it has never run correctly, nor did the one I bought direct from a retailer shortly after... then - I found Slot-It, and so commenced a long affair with collecting SI GT40's... eventually building a white kit one that I call "Godzilla" - almost impossible to drive - huge motor, very low gearing... I've learned a bit since way back then.... 

 

Ok... one down - 9 to go.

 

Currently on the bench are three NSR 86/89 F1's, two NSR Moslers, a Mr Slotcar McLaren M6A, two T/slot McLaren Elva's, a T/Slot Lola T70, a Revo-Slot Porsche 911 GT-2 white kit, two Revo Porsche 911 GT2's, a Revo Dodge viper and of course - work continues on the LJ XU-1 build.. it has to be completed before Bathurst next year - the 50th anniversary of when PB took it over the finish line to claim his first Bathurst in 1972..

Ok, guess I'm back....

frats,

Rosco

Hi Ross, although I don't recall having any problems with the interior of mine it had quite a weak motor instead. Needless to say I replaced it but I used a Piranha 21.5 instead, and it must be a strong one as it really flies now and it doesn't need any added ballast as my Slot.it versions required.

Thanks Bram,

I haven't run any of my new cars yet.... no track.

Normally, I spend a couple of hours setting up an 12.5 metre layout on the Bathurst weekend - looking forward to that so I can finally get to play with some new toys....

I have a fairly good understanding on how all the Slot-It GT-40's go.. it will be good to compare how this NSR one does, and yes - it has a slightly smaller motor than the other NSR's... only 165g/cm torque, but still up at 21.5 k... 

 

I'm starting to take a bit of notice of torque specs lately.... gives me something to work on with regards final weight of a model... rpms, I relate to gearing.

I'm guessing this is what others do...?

 

frats,

Rosco
