Written by: Derek Buono

Tekno started out making wing mounts for a REVO and has taken that love of aftermarket perfection more than just 1 step farther, but more like however steps it takes to run a marathon! The new EB48 (boo on the name) is the result of lots of testing and late nights. We had a long conversations, and a few adult beverages with Daniel from Tekno and we’re excited to see how this ground up design will stack up against the legends of 1/8-scale. For now here are the specs and when we get some more pictures or details we will consider sharing them.

00% Tekno RC Designed and Tested in Southern California.

Chassis:

Designed to be electric from the ground up – no nitro conversions here!
4mm CNC 7075 aluminum hard anodized lightened chassis.
Super narrow chassis – widest point is only 125mm (less than 5”) mudguard-to-mudguard.
Class leading front and rear clearance (short chassis overhang) provides better bump handling and jump landing.
Integrated battery tray/mud guard, battery is sunken into chassis for a super low COG.
Integrated electronics tray/mud guard for easy removal of electronics.
Spacious, enclosed, easy access radio box with integrated transponder mount.
Single pack configuration is better balanced, lighter weight, and makes battery changes easier. Battery tray accommodate 2x2s packs.
Adjustable chassis brace system for fine tuning flex with front, center, and rear braces.

Differentials and Drivetrain:

3 fluid filled adjustable super lightweight diffs.
Less rotating mass = better acceleration.
Straight center driveline for maximum efficiency and minimal wear.
CV driveshafts with captured pins on all 4 wheels.

Shocks:

Super smooth 16mm big bore shocks.
5mm CNC 7075 aluminum shock towers are standard.
Innovative cone piston design (not just tapered) provides varied compression and rebound rates.
Fully adjustable long travel suspension geometry maximizes stability and traction while providing superior cornering and on-power steering.
CNC threaded shock bodies, caps, cartridge caps, and adjustment nuts.
4mm hardened steel polished shafts.
Triple guide design for true consistent shaft action.
Options for vented cap, emulsion, or standard shock configurations.
Optional spring rates and spring kits are available.

Suspension and Steering:

Adjustable length rear arms to suit any track condition.
Adjustable front arm sweep and angle to make the car more aggressive (swept forward), or easier to drive (swept back).
Front and rear arms can be used on either side, rear hubs can be used on either side – less parts in your toolbox.
‘Narrow pivot’ steering posts provide ‘0 bump’ geometry with almost ‘0 steering slop’.
Adjustable CNC 7075 hinge pin braces are standard.
4mm inner, 3.5mm outer hinge pins, polished for smooth action.
Adjustable Ackerman and bump-steer (bump in, 0 bump, bump out).
CNC aluminum Ackerman plate rides on 4 precision bearings.
LCG rod ends and lightweight turnbuckles are lowered by 5mm.
Front/rear sway bars are the same length = less parts in your toolbox.
Adjustable steering stops for precise steering travel settings.

Motor Mount:

2-piece CNC aluminum motor mount with precise dual clamping gear mesh adjustment.
Lightweight direct-to-diff mount design.
Use standard MOD 1 pinion, Tekno RC Traktion Drive or Elektri-Clutch.
Use motor brakes or mechanical brakes, the choice is yours.
Easily accommodates ‘Truggy’ or ‘Long’ can motors up to 78mm long.

Other Features:

Lightweight easily adjustable wing mount system.
High downforce wing included.
