Darren is correct: the X - 5 Squared (All X - 5s, really.) uses the inserts found in the donor car.
When we build these Kits we use as many parts as possible from the donor car. No sense to not use them. as you'd otherwise throw them away, and it helps keep the Kit price as low as possible.
In the case of the motor screw inserts, the length of the inset is critical, and the chassis is built so they just snuggle up against the top of their holes. This prevents wobble which leads to cracked chassies. We didn't have this exactly correct in the original chassis, and it's one of the improvements in the Squared.
The X Factory inserts made for The New Math (Which are better, we think, because of the knurling.) are a bit shorter than Losi's motor inserts, and so do not work as well. The X - 5 chassis is made for the Losi insert.
In a pinch I think you can use an X - 6 insert in an X - 5 but we have never tried it and I think the knurling may screw up the chassis so that the Losi insert no longer fits properly. Therefore, I suggest you search for the correct Losi part #4224, which any well-stocked model shop should carry.
