A few months ago a Losi 5ive-T clone and clone parts have hit the market. Since there is evidence of a number of problems regarding reliability and tolerances of these parts, we acquired some parts and tried to portray some distinguishing features for you.

The genuine Losi 5ive-T plastic parts are sometimes less shiny than the copy, as can be seen clearly in the picture of the rear a-arms.
The hinge pin holes in the a-arms are noticeably larger than those in the genuine part. Therefore the suspension using these a-arms inevitably has more play.

One particular mistake happened when copying the rear a-arms. Here, the labels "R" and "L" have been mixed! Since we had no front a-arms for comparison, we don’t know whether this does also apply to the front version.

However, the property of the plastic material of the clone parts is different. For example, the surface of the clone transmission case is slightly "marbled". And when you put the two parts of the transmission case together it has gaps way beyond good and evil.

However, if you pay attention to details one can recognize quite a few differences already at first glance, which will clearly tell you what a clone is. Differences are considerably easier to see with the magnifying glass function of our shop system.

Of course, particularly problematic are dimensional differences that require reworking for the installation of the clone part in a genuine Losi 5ive-T and are likely to have a significant impact on wear resistance.

We have compared only five parts. And even this comparison tells a lot about the nature of the parts! These are the discernible differences are shown:

The distinguishing features of the steel parts are even more visible by just looking at the finish.
The clone parts look dull and the surface looks kind of "raw or rough" showing a lot more and bigger tool marks than the genuine Losi parts.

Of course, dimensional accuracy of the steel parts is far more important! And here quite critical differences can be seen:

The shaft diameter of the clone differential drive cups is two hundredths of a millimeter smaller, and that is significant in terms of fit and wear for this application! The driving pins wiggle a lot in the holes! The bore is not made at a precise 90° angle to the shaft; the pin can only align square to the shaft because of the (too) large bore.

In condition of delivery the slot in the drive cup for the dog bone pin shows already about 0.1 mm more play than the genuine part on one side, on the opposite side, however, slot width is the same as the Losi part.
0.1 mm does not sound that much; 5.3 instead of 5.2 mm does not appear to be essential. However, it is 0.3 instead of 0.2 mm, a hefty 50% more play and will inevitably become a problem.

We had no problem to scratch the clone part using the genuine part, but no scratches vice versus!
That tells a lot about wear resistance!

The CVD shafts seem to be made of cast steel, looking at the surface finish, even a blind man could tell the difference compared to the genuine parts at once. Remachining of mating surfaces is unclean, without prior deburring the CV couplers have to be forced into the CVD side of the cardan shafts.

We've also had the first 5ive-T clone, together with frustrated buyer standing in front of our counter.

What we noticed at first glance:

The wheel hexes had enormous play on the axles, they are drilled too large. The gap is visible with the naked eye, the mounted wheels wiggle accordingly significantly.
The installation of genuine Losi wheel hexes eliminated the play.

Otherwise, the buyer had to grapple with several shortcomings just during the first tank of gas.

In summary: At first glance the clone looks like what you would expect from a copy! Just like a "real" Losi 5ive-T.
Certainly one can but assume that the owner will not have as much fun with the clone as the real thing!

If you, reading this, recognize that you have been taken in by such a clone, we will also help you as far as we can, of course. We are sure that with time a lot of genuine Losi parts will find their way into your car, if it is supposed to last in the long run. If you have any questions, we are glad to help.
