Cartrix Acura NSX - hybrid re-chassis

[vtecfour]

Got a pile of the Cartrix Acura NSXs after seeing a review on HRW many years ago.

Curious to see how one runs with a hybrid chassis so the build begins.



Cut metal for the chassis including,

.055" piano wire - main rails and front axle supports
.062" x 3/4" brass strip - guide tongue/front axle support
.062" x 1/2" brass strip - guide tongue
.062" x 1/4" brass strip - motor pod support cross members
5/32" brass tube - guide tube to be bored out to 9/64" for Sloting Plus Universal Guide, 7mm deep
1/8" brass tube - front axle tube

Motor pod's a 3DRon sidewinder S can resin printed one with Parma 3/32" x 3/16" axle oilites.

Soldering begins.

Chassis's running with these assembled parts.

front wheels/tires - stock Cartrix plastic/Slot It low profile low friction
rear wheels/tires - Mitoos 19mm/home made urethane
motor - Piranha 25K S can
pinion/crown gears - Slot It 10t/Slot It 36t
guide - Sloting Plus Universal, 7mm deep







Tri-post mounted the body as usual.









Cut and filed the original rear plastic rims into wheel inserts.



Has good stick in the corners and plenty of speed. A bit noisy with the mounting screws all tight but some loosening cut that down noticeably.

Onto the next build.
