More testing on the BullRing. Here's some results listed worst to best:
1/32 Carrera Roadrunner stock car. Stock wheels and tires front & rear. Body has been lowered on the chassis. Full interior replaced with cardstock & cut down driver figure. Magnets removed. A little lead in the front & rear, low in the chassis. Difficult to control in corners. Slides just a little then wham, on it's roof! Better, but still mostly sucks!
1/32 Carrera Aston Martin (007 car). Stock wheels & tires. Body slightly lowered on chassis. Full interior removed and replaced with flat card stock. Chassis is stock, no weight added. Works suprisingly well. Bettre than the Carrera Roadrunner, but still challenging in the corners.
1/32 Scalextric Taurus NASCAR. Sidewinder chassis. Golf club lead applied to underside of chassis. Rubber tires from a Scalextric Camaro. Works pretty well but needs a better guide flag - too shallow for 1/24 routed track.
1/32 Slot.It Lancia. Offset anglewinder pod. Independant rotating front wheels. Just a little lead up ahead of pod. Stock rubber tires. Not too bad - needs more traction.
1/32 Slot.It Nissan R390. This one has a bunch of lead added. That's about it. Works pretty well.
1/32 Slot.It HRS chassis based stock car. This is the Monte spec TCONY car (see details of mine in the gallery). Inline motor pod. Urethane rear tires. No weight or lead added to the chassis. This thing works great! Very fast & handles extremely well, much better than I thought it would!
1/32 NSR Mosler. STOCK. Anglewinder motor pod. NSR rubber rear tires. Unbelievable! Fast! Handles GREAT!
More to come...... -------------------Bill
