I purchased a 6s for my first car at the same time I purchased 3 mega500 starter models for my kids. The 6 s is amazing, everything Jondilly said above. It’s fast, it’s strong and yes expensive. Like all typhoon models there is a throttle limiter on the controller so you can run it at 50 or 75% of full power. However 3s is plenty fast, has more plastic than metal, won’t stand up to hitting a curb the way 6s will but the parts are less expensive and fixing the car is fun! Either one will be lots of fun. I’m upgrading controller receiver and ESC in my 6s so I’m well on my way to 2k. I don’t need it, I just like it .Yes you can run the 6S on 2S, 3S, 4S, or 6S. I would actually say run it on 4S to start.
I would say they are both worth owning but choosing one is going to come down to how much space you have to run. The 3S would be great for a small yard or track. It will be easier and cheaper in the long run.
The 6S our of the box will be faster and will need more space to stretch its legs. However, maintenance and parts will cost more. There are tons of upgrades available. You can easily spend $2000 on this buggy if you want. Don’t ask me how I know. ?
Which electric driver to you like?6S no question. If u can study engineering and pass, u got skills to repair any damage to the rig that may occur. This is a great hobby, hope u join sooner than later. Electric screwdriver with quality bits will save time and pain. Trust
