RE: Genesis NX76 engine. Bearing problem
I am not using the Collari 32 in a Genesis, i had the NX76 engines in my Savage. (Conversion set from New Era Models)
The Savage is almost 2kg. lighter than the Genesis so the NX 76 engine really is powerful in a Savage.
It was fun until the bearing broke.
The Collari engine is also very powerful, it has a lot more top speed and pulls wheelies very easy. With the 3 speed and dirt bonz tires (220gr. tire+wheel) it sometimes flips the car around when it shifts from 1 to 2 gear.
