Building this for a coworker. There's now three TA06s at my work :-) Two of them with Tekin Redline RS 13.5 and one 17.5. Let's see how they hold up with all that speed.
The TA06 is gear driven rear and belt driven front. The diffs are oil filled gears. Will be a complete pain to tweak. Also the battery door takes 4 screws and tiny rubber O-rings which is cool if you want to run one battery and not swap. But most people tend to swap. I ordered a 6000mah battery for this reason, but it is too tall. Tried to swap it out for one that fit at ultimatehobbies but they were incredibly unhelpful. Now on my shitlist :@
