From my experience the flex track is louder and slides more on smooth surfaces.
Sorry for the fire hose lesson, I got on a roll.
- The basic configuration of PF is a battery and something you're powering (like a motor)
- The next level is adding remote speed control via the IR transmitter (the remote control handheld) and receivers (installed in the trains)
- The battery won't power "light bricks," but instead the power function LED lighting lead pairs (two lights on each connection)
- Be aware, stringing bulky PF wires/blocks throughout a chassis can get difficult and ugly quick, as they are not very versatile. It's doubly so if you're jumping wires across train cars
- It's not "8 other devices," but 8 total devices maximum
- It's not necessarily "devices" in this instance either, but rather power flows (stick with me)
- The 8-way control comes from using the IR transmitter & receivers, allowing for control of up to 8 individual power flows, with each one requiring an IR receiver (you only need one transmitter)
- To clarify above, IR receivers allow you to control up to 2 power flows each. Usually this is configured to control 1) the motor and 2) the engine lights. Such a configuration would take up 2 of your 8 available slots, leaving you with only 6 left to play with
- A power flow usually powers only 1 device, but you can piggyback multiple ones on a power flow. For example, you can have two motors on the same power flow, or 2 lights, etc.
- Piggybacking lights and motors on the same power flow is not ideal in most situations, because the light brightness will vary as the motor speeds varies, which would look weird on say, a train
- Be careful piggybacking multiple motors on one battery. 2 is fine, but more than that might put too much drain on the battery and could damage it
- You can theoretically piggyback as many lights as you need, as LEDs are dirt cheap when it comes to power consumption
- As you can imagine, any and all things piggybacked to a single power source will respond at the same time when that power source is controlled, i.e. all motors will rev up at the same time, all lights will turn on, etc.
- Invest in the rechargeable battery, seriously
The winter village sets are going to join the scene and Minas Tirith has lost the black outer wall and become a big mountain. The grandsons should be amazed for Christmas eve - the trains can go FAST.
Most PF trains support dropping one of these in the engine. Creator trains include instructions for fitting them (except Maersk), its usually fairly obvious how to fit them in the city passenger trains (although i've not figured out how best to run wires from the front engine to the rear engine and its lights). The 2010 cargo train (7939) can fit 2 sets of these lights nicely for front and rear lights. The red cargo train (3677), 2014 cargo train (60052), and maersk cargo train (10219) have decorative transparent studs mounted on various angular bricks and solid engine fronts theres no way to add LEDs without totally redesigning the front of the engines to add LED holes.
The older RC trains come with older light bricks fitted as part of the build.
