Online social commentary (media commentary):

How to get Inside the RIPSAW drift tank gearbox, how it works, possible motor upgrade is what I was thinking but I could not find a faster 390 motor and from the look of the motors com and brushes it looked like it handled the 3S lipo battery fine so I just decided to leave the stock motor in it.

Really interesting! It looks like a well engineered and built tank, it's always nice to take things apart and see how they work.
Nice video. Really liked your explanation of how the gearbox works. It's great in the way the steering and drive functions are separated yet together. This means the tank tracks dead straight so the fact that the stock Tx has no trim function really doesn't matter. Of course with your modified set up you can use a better transmitter anyway. I can relate to the grease getting all over your fingers - I had the same experience when I pulled mine apart :).
Hey Shen, great teardown, havent truly pushed this baby yet, but so far im noticing that it turns on a dime much faster clockwise then anti clockwise. almost like something is binding or slowing it down when turning, also when crawling in tight or rough terrain situations the turning motor doesnt seem to have enough torque. Any thoughts on an upgraded steering motor?
"Great Video , Diff System is very advanced, saw a similar System on a R/C Truck from Radio Shack back in the mid '90s... only it was a 6 wheeled Dump Truck with conventional steering on the front axle. Believe it or not, they used the Diff System to Control the Steering instead of a Servo, Diff allowed steering motor to turn after drag link reached it's limit and prevented steering motor from burning out.

I admit, your Ripsaw has a more advanced system than Kyosho Blizzards... But the Motors are actually the least Expensive part of both Ripsaw and Blizzard Drive Lines... Kyosho Blizzard Line is designed to be abused and easily modified, Ripsaw isn't... unless (of course) someone has Your Skills!
" Great video! And I want to ask -what type of grease did you put into gearbox? My other RCs have metal parts in gearbox, so I used to put some unversal grease-motor oil mix with good anti-wear results.
Excellent disassembly and great explanations, good info.
That¡¯s very interesting to see how it works inside nice share bud! Love that rpm checker too how much does one of those cost?
Awesome video dude! I was super curious how the transmission worked with the second motor on top
Nice, in-depth look Steve! Pretty impressive!
For toy grade RC that is one helluva clever, complex gearbox. I have no interest in owning one, more interested in scale speed 1/16 tank stuff but thought about buying one just so that I can marvel at that gearbox!
Very interesting design looks like you can change the steering motor for a servo, good video
"Thank You Sir!

To be honest, your video gave me reassurance in regards to buying this for my son!!

10 Star Video Sir :)
" I¡¯m really surprised they went with a double differential transmission instead of just using one motor per track
Cool test with the RPM meter woud have been nice to know the steering motor RPM. I put a brushless 5000KV 2845 motor in mine and run it on 2S lipo so about 37000 RPM. I wonder what woud happen if i put in 3S with 55500 RPM :D
yup 24k+ is a fast 390. really clever how they made the little 130 motor control speed of both tracks so nicely and proportional like it does!
Cool info,pretty cool the way it operates
Great video, maybe too advanced for me. I've heard a few people have steering but no drive so it's most likely the 390 motor is kaput? I fancy one of these just to run with a friends 1/16 Tamiya tank!
Cool, thanks for looking in there for us, I'm not smart enough to make sense of the gearbox on these but now at least I have a reference for someone who is
