The Porsche and Bugatti had a hollow space in the middle for the instructions but the Lamborghini need an "hole" under the box which was made using cardboard in order to make an empty space for them.
Seeing the new electronics lineup posted in the 42113 forum makes me wonder if there's a possibility lego is going to give us the Simple Hub with the set to power the gearbox functions but not drive.
Maybe the new CV joints introduced in 42099 can withstand that amount of stress
I just saw your thread about the damaged joints, guess they won't work.
Just did some research and found that the Lamborghini Sian has a motor integrated into the gearbox which adds 34 horsepowers to the output and the Sian does feature a rear locking differential. I wonder what's Lego going to do with this.
I also have 2 buggy motors which can go forward but it wouldn't go in reverse. I've tried controlling it with Sbricks, Ir remote controls and even with direct power from the battery pack but it doesn't seems to work out. Anyone can help? I don't think i'll be able to replace the motors since they are so valuable
