WIP_firetruck (3)
One more change that needs to be made is to the ladder's attachment. I can prop up the ladder and extend it, but the construction is just a bit too flimsy. I'll need to play around with some technic elements to make it stronger.
It is getting quite heavy and the top speed isn't too impressive, but the large Power Functions motor has few problems giving it a fairly spritely acceleration. I initially used six- long axles for the drive wheels that didn't meet in the middle. However, the motor produces enough power to pull the gears out of the differential between them. Using 7-long axles that do meet in the middle prevent this from happening. I suspect that the motor does drain the batteries quite quickly, but have built the truck such that I can pull out the battery box without too much trouble. I am pleasantly surprised by how sensitive the IR receiver/how powerful the transmitter is. The receiver is not in a very prominent place on the truck and yet it seems to pick up the remote's signal even if the direct line of sight is blocked. Reflections apparently are enough.
