In his later vids you can see in Japan they have successfully progressed onto RWD drifting. They seem to run on that roll out carpet type surface. I've had some success in my garage with a big rear weight bias, but nothing like the speed and counter angles these guys are getting.
yeah dude they have got rwd on lockdown, especially that dude with the orange car with yellow wing. iv tried out both front bias and rear bias lately in the shed. so far i found the easiest but really slow and hard to switch was front bias. but so far the best iv found is like you with a rear bias, a little harder to catch but switches when you tell it to and also alot faster that a front bias. im going to start playing around with battery placement, i saw one of his other cars he has a mid rear motor but batteries mid front, so would probly end up almost a 50/50 weight split. still trying to get more consistant in the shed tho b4 i start trying that stuff. haha.
Edited. got the type of car wrong, i have possibly corrected but probly still wrong hahahah.
