RC73. My Memory Having RC Car. My no 48 RC. Tamiya TGX MK1 Pennzoil Nismo GTR #44011 1/8 Nitro 1998.

My next no 48 units RC. Buy for Rm200, saler from Klang Selangor 7/2/2023. Tamiya TGX MK I 1/8 Year 1998 original with Pennzoil Nismo GTR body. Come without body and Transmitter. Using FS15LT engine. Look like some problem in this rc, put a side for long time never repair. Will postmortem when i get it. Assembly manual download.
On 9/2/23 i got the car, after checking and remove parts, from my point of view this rc buy new just play few time in a carefully manner because no scratch on bottom chassis only miner scratch on front bumper. Another thing when dismental, parts screw dam tight and most screw with shining tread. Few thing found didn't propper assembly, there no greese on front and rear axle gear like new. No parts damage, engine compression still good no much slush. I thing, i got a jack port rc again, in good condition but dirty.
