4 Epoch 4: Rescue Rig Day
Epoch 4 Total: ~$44-50
Adding the tow crane/winch and lights. The winch actually works—you can set up rescue scenarios, pull stuck toys, create obstacle courses where the kids have to winch up hills. Lights make evening drives possible.
After this epoch: Functional winch, working lights, way more play scenarios.
The kids’ job: Operating the winch, rescue missions, night drives.

4.2 Q&A
Which channel does the winch use?
Channel 3. This is why we upgraded to the 6-channel T6 radio in Epoch 2.
What lights work with the BUG18 body?
The 4M-16 headlight/taillight kit works with any body. For more options, check Injora’s LED lights for rock lights, whip lights, and LED strips.
Does the winch actually pull?
Yes! The 7kg servo has real torque. It can pull the truck up slopes or drag other toys. Great for rescue play scenarios.
