RE: Tamiya TG-R
Here are some pics of the TGRs and TGXs. The back row is just some spare and basher bodies.
The red car is a Tamiya TS 020 GT One body. It will only fit a TGR. It has the flat head Tamiya FS15RS. The RS has the same piston/sleeve design as the FS18RS in the LT case.
The Silver car is the Mercedes CLK GTR. It has the silent OS LDX flat motor. You can see the exhaust tube that diverts all of the mess out back. The tube does not quiet it much.
The Porsche GT1 is one of my favorite setups. Alot of rear camber with foam tires allows this car to slide controllably through corners. It steps out until the suspension squats enough to put the tire flat on the pavement. Then it grips. It is really impressive to watch, and it makes you look like a great driver! When the tires cone down, it is no fun.
The Acura NSX was confiscated by my wife. She loved the decals and design, so I gave it to her. I have never run it, even though it is RTR.
