This MOD upgrades your CAT D11 as below:
- increase the blade lifting speed by 67% (the Control+ app needs to be calibrated after this MOD)
- close the gaps near the front panels
- make the front linear actuators look stronger
- replace the rear fake linear actuators with a real one; they can be controlled manually to tilt the ripper
- add 2 fire extinguishers near the cabin
115 extra parts are needed. The most expensive parts are the 2 black linear actuators (43097). Replace them with the LBG one (61927b) is fine. Or just like me, sprayed the LBG one with semi-gloss black.
