Got another big Buggy 1/8, buy for Rm150 on 15/10/2025, saller from Kajang, meet up Bangi Kip Mall cod. A 2017 Tekno NB48.4 1/8 Buggy made in USA. I think this the new first batch after 2016 NB48.3. Because using Reds R5R 21 engine. Diffrent in C hub with ballbearing, front suspention using long hinge pin, absober top cover have refill hole, C hub using kingpin screw.
This rc have a big accident broken the rear axle mounting for damper. Then put a side until parts rusty and center gear full of mud. Spare parts a big problem in Malaysia. Very famoust on that few years in europe, aliment can be adjust according the driver handling. Good handling in track. More improve next new batch Tekno NB48.2..
Update blog = 28/10/2025.
2017 - 2025 = 8 years (USA 🇺🇲)
