Snow White is a beauty!
It is a race car built by Jaeho Jung (sunsky or sunmint1, depends wherever you find him) [1, 2, 3] for the "1st BrickInside Power Function Racing Contest" (The LEGO racing contest from one South Korean LUG).
This Drift Parking video, should give you an idea how this machine is something special and much care was put on its construction (also those skills to park the car might be of use... ). An outdoor video from Jaeho Jung playing with his racer can be also seen below.
Gear Ratio for drive is 1:3.75 overdrive, and so the car is quite fast (about 2 m/sec on smooth surface). The car was intended fast for the contest but turned to be a bit difficult to maneuver sometimes into an obstacle course, because of its high-speed according to the author.
The car itself seems very well built in its modularity and having a good bunch of details for its size.
Smooth curves, the Racing look and its All White color, are also quite distinctive in this model.
Jaeho Jung made an extensive and comprehensive review his car, at BrickInside Forum, which he had the courtesy to translate into English for all us being able to read (it's worth reading).
Along with his review, he also added lots of photos that would allow you to understand all the details as well to build a copy if you like, or to get some ideas for your own.
Following some Snow White technical data,
- One XL-motor for the drive train and M-motor for steering.
- Versatile and easy custom driving module.
Overall 1:3.75 gear ratio, resulting into overdrive and a too fast car, but different gear combinations (16t > 16t or 12t > 20t, instead of 20t > 12t in the right photo) can be easily applied to slow down the car and fit some different purposes.
- Return to center steering mechanism, inspired on Ian Power's idea.
- Working headlights, when battery switch is on.
- Scissor doors.
- Ground clearance, about two studs (2L).
- Strong roof, to protect passenger against overturn...
- I loved the chassis construction, but also specially enjoyed the solution applied on the PF remote handle. An unexpected use for part 41667.
Also the the white liftarm position can be adjusted to the driver's age or hand size.
Definitely must give it a try!
In order to enter the "1st BrickInside Power Function Racing Contest" held last 15th of August, the Snow White (aka BaekSeolKi, 'Snow-White Machine' in Korean) had to be compliant with a few contest rules, like:
- Must fit in a 32x32 studs area.
- May use up to 2 motors and only one PF receiver.
- One PF battery box is allowed.
The contest included 3 categories: Racing, Design and Popularity and Snow White got 2nd on the Racing category.
You may find a lot of photos from the contest at BrickInside forum [4, 5].
