HI Bob, you and the lads will be very welcome.
In both magnet classes only one mag is allowed. The reason for stating it should be fitted inside is because one local club to us fit their mags on the underside of the chassis and we reckon that`s nuts,
Of the cars you mentioned, the Scalex GT 40 is by far the better choice, Get your rear tyres down a third and you have a great chance.
There is no upper limit for motors in the non mag class. BUT be warned,our circuit does not favour high power. You need good grip and good braking ability, too high powered a motor and you will struggle. I`ve posted that the leading Phoenix club racers use box standard Pro Sliot toyota GT 1 and Slot It audi. These are run loose with soft tyres at the rear and skinies at the front,
Hope this helps and we look forward to seeing you guys
