[Instructions] Motorize LEGO Technic 42232 Koenigsegg Sadair's Spear with BuWizz 3.0 and BuWizz motor

***Important Notice***
Due to the serious issue of unauthorized selling of my instructions, I have to increase the watermark coverage area. In order to protect my work, I hope everyone can understand and support this decision. The watermark has a very high transparency and will not affect the building. 

This RC modification transforms your LEGO Technic 42232 Koenigsegg Sadair's Spear into a fully remote-controlled machine — requiring only 9 extra parts, 7 motors, and 2 batteries. With minimal additional pieces, it’s an ideal entry-level project for builders new to full RC conversions.

A 5:1 reduction gear ratio prevents the BuWizz motor from failing to operate effectively due to excessive vehicle weight.

Since two 8-tooth gears are driving 24-tooth gears in this gear reduction setup, please avoid aggressive driving to prevent damage to the 8-tooth gears.

Less extra parts. More savings. Maximum RC fun.
