LEGO Technic 42075 First Responder RC mod

This is the remote control modification of the LEGO® Technic 42075 First Responder. This time instead of more powerful and expensive components this mod uses only the Power Functions elements of the set 42075 RC Tracked Racer with a few other extra pieces and it is still very fun to play with 🙂

Features are:

– M motor to drive the rear wheels
– M motor for steering (return to center with rubber bands)
– IR receiver and IR remote for control
– AA Battery Box
– Fake engine driven by M motor
– Raisable light tower and some accessories are still available

Part list can be found on rebrickable and at the end of the pdf instructions.
