Some build notes:
- Tracking down the special front belt for the YR-4 2 Special, which is shorter than that of the standard YR-4 2, was a pain in the ass. What is more annoying is that once installed I discovered the (NIP) belt slacks and skips even with the chassis adjusted for maximum belt tension

- Another problem was the choice of layshaft: The original standard layshaft from the YR-4 2 standard with locked spur size was discarded due to a chewed up spur. Both of the alloy Yokomo versions with center oneway I had were made out of supersoft aluminium

- Motor mount: one of the wreckers included the very nice alloy Yokomo hop-up.
- Hinge pins: Blackened steel ones were included with the YR-4 2 standard, while the Special junkers had regular steel ones - which had rusted (another WTF choice by Yokomo

- Stainless steel hard universals on all four corners.
- Ball diffs are not super-smooth, but good enough. That little spring washer makes setting the diffs very hard. Not my favorite diff design.
- Battery hold-down and gearbox tops are wrong for the YR-4 2 Special: FRP instead of graphite.
- The bumper is an optional part that was included with the YR-4 2 standard.
- Tech Racing front camber link set. Other turnbuckles pulled off donor cars.
- Those little red shocks...I wonder if they actually do much absorbing?
- Avid bearings all round.
- Alloy steering shafts + ball bearings
- I have the correct wheels for the car, but not the correct tires. I would like to find street tires.
- And I've got the so-often-lost battery foam

Electronics have been sourced and will be simple: Sanwa 27MHz AM RX, Sanwa BL-Fighter ESC, Sanwa standard servo, 15 turns machine-wound modified motor
