Portal axles on the FCX24 lift the diff, multiply wheel torque, and cut torque twist. How micro crawler hub gearing works and what a kit changes.
RC Cars
Radio control crawlers, bashers, and buggies, tested on price, drivetrain, and how they actually drive.
A carbon chassis stiffens the FCX24 and drops it lower
FCX24 chassis flex drops away when a Furitek Grasshopper carbon frame replaces the plastic tub, and 39g of brass links lower the center of gravity.
Fit dual-stage foam and 1.0 inch SCX24 tires stop folding
SCX24 1.0 tire inserts decide grip: dual-stage foam props the sidewall, soft single foam folds off-camber, and silicone keeps the tire round.
A 3200KV outrunner drives the FCX18 LC80 from the box
FCX18 LC80 brushless power ships factory-fitted, pairing a 3200KV outrunner with a separate ESC, a two-speed gearbox and metal-gear portal axles.
Overdrive gears let the SCX24 climb without flipping back
SCX24 overdrive gears speed the front axle by 33, 23 or 14 percent, and pairing a front overdrive with a rear underdrive steadies a steep climb.
