Tekno RC EB48.4 4WD Competition 1/8 Electric Buggy Kit
The Tekno EB48.4 4WD Competition 1/8 Electric Buggy Kit once again raises the bar in the 1/8 e-buggy class. Tekno has improved on nearly every aspect of the buggy with a variety of fine adjustments, and a leap in overall performance. These changes feed into Tekno's desire to manufacture the best handling, most consistent, most durable, and highest value kit on the market. Tekno is confident that you will agree that they have delivered on these goals.

Easy instructions and great setup sheets. Tip for all: download instructions for simple guide to setting up emulsion shocks...
Big smooth shocks with innovative mounting and springs with plenty of adjustability.
Big heavy duty bearings throughout
Plastic in some areas are soft and require delicate, almost baby hands, when tightening despite the 2.5mm hexes. The centre diff mount and chassis braces in particular are soft in comparison to my Losi. The Losi uses a lot of plastic with metal nut inserts where structural strength is required, the Tekno doesn't. Tekno admits to removing an additive they claim makes the plastic hard and brittle, the compromise however is the softer/flexible plastic can be easily stripped or under tightened for fear of stripping. I gave up trying and optioned the aluminium centre diff mount which really should be standard. The plastic pieces are rubbish - too much flex and a pain to tighten. This is 1/8 off-road racer not 1/10 crawler.
Centre chassis brace restricts smaller pinion selections and/or larger diameter motors ie Team Orion. With a standard motor I can only just fit a 14T pinion but it doesn't mesh all too well. Removing the brace introduces too much chassis flex. Big jump or hard crash, without the brace the only structural piece stopping the buggy from folding in half is the beautiful long lightweight driveshaft. And no, as good as it looks, it isn't good at taking a hit. After two race weekends I bent one and therefore have since made changes to pinion and motor to get the centre chassis brace back in. In a bid to reduce drive ratio from the .3 to .4 model, Tekno has produced an issue that will be difficult to remove without a complete re-engineer of the layout. The new hot bodies buggy uses a centre rod which is clever.
At full steering lock, standard wheels will rub against the springs if mounted on the outermost hole. Reducing servo travel helped remove this issue.
Very tight ESC location. It's clear this buggy is designed for a tekin setup. You can get a Team Orion Vortex pro X in there but the wires will get very close to the driveshaft. A few more fractions of an inch in girth couldn't have hurt, particularly when the shaft takes a knock, bends and then wants to burn its way through your expensive ESC / Lipos... (Note: stop when knocking is heard...). EDIT... I've since cut into the ESC tray and reduced its height. That has given me a marginally better clearance between driveshaft and wires.
Very tight motor mount, I was using a screw driver to lever the motor back and forth but found adding an old diff gasket onto the face of the motor fixed a problem that should not be there in the first place. The tight angle of the mount also makes it trickier to set backlash than the losi.
Overall, I do like the buggy for its innovation but it's certainly not without its flaws. Would I recommend it? If you have team Orion gear, no. Beginner, no. The rest, perhaps see it in the flesh first or do your research.)
