Why the Tekno ET48 2.2 Changed the 4S Conversation
Tekno positioned the ET48 2.2 as a true fourth-generation update—three years of development and testing across US and European tracks, with the goal of improving handling predictability and durability without losing the “race kit” feel. The redesigned chassis supports 4S shorty packs, and the platform shares broad compatibility with the EB48 2.2 and NB48 2.2 family, which is a big deal if you like parts commonality and easy spares planning.
What ET48 2.2 Drivers Typically Want from a 4S Pack
- Stable punch under load — clean acceleration without the “soft” feel when the truck is heavy, geared up, or the track is high-grip.
- Predictable voltage behavior — the truck stays consistent from minute 1 to the final laps of a run.
- Hard case protection — especially useful for truggies that see more cartwheels and strap pressure than buggies.
- Fit flexibility — the ET48 2.2 chassis layout makes shorty packs more practical, so you can tune weight distribution without fighting the tray.
Picking Capacity by How You Actually Drive
- Race feel & balance first — many drivers prefer a lighter 4S setup (often a shorty-style pack) to keep direction changes sharp and reduce “push” in tight infield corners.
- Club practice & mixed sessions — a mid-to-high capacity hard case pack can give you longer stints while keeping the truck planted and predictable.
- Backyard bashing — prioritize capacity and case durability, then manage heat with smart gearing and airflow (fan/ducting).
