TKR5507 – SCT410.3 1/10th 4WD Competition Short Course Truck
This is the Tekno RC SCT410.3 Competition 1/10 Scale Electric 4WD Short Course Truck Kit. The SCT410.3 is an updated version of the original SCT410 with a slew of updated parts and improvements. The SCT410.3 leapfrogs over the 4×4 SC competition in terms of performance, durability, and value. Tekno RC has their customers’ best interests at heart so there is a clear path to simply upgrade your original SCT410 if you already have one. But there’s also nothing like a fresh new kit that goes together like butter!
With the SCT410.3, Tekno wanted to improve performance and increase value to the customer without increasing the price or compromising on the great qualities of the original. To do this, they went through the entire platform and made changes accordingly.
