I used both. they both have pros and cons.

Tekno has much lower CG, its battery tray lays tightly on the chassis while the Losi tray is about 10mm higher above the upper surface of the chassis, making the battery look like living on the 2nd floor.

Tekno's motor mount secure the motor very firmly, totally worry free, while the same thing makes gear mesh adjustment a painful experience.

But this chassis mounted motor have issues of varying gear mesh during chassis flexes

Tekno use none standard long shank pinion that cannot be found anywhere else.

Losi kit saves you some bucks by not wasting a cent in clutch.

Pinion change and mesh adjust is much easier in Losi kit.

With Losi kit you can run plastic spur for a quite ride.

With Tekno you must use 13T+ pinion to have secure pinion-spur contact. Actually I bought myself a 49T(1 tooth larger than stock) robinson spur to use 12T pinion for a proper gear ration when run 6S on 2200KV MMM combo.

You can't use Hacker or Feigao motors + pinion gear with Tekno for their shaft lengths.

Your motor bearings will take more stress and wear quicker with Tekno long shank pinions.

Tekno kits' CG shifts about 10~20mm to the rear end away from center.

Tekno kit takes packs no longer than 145mm, Losi runs 168mm pack with no issues.

Tekno has beautiful colored chassis compared to Losi 2.0's deadly dark metal sheet.
