Picked up a lionchief BNSF RS3 from a starter set breakup. Brand new for twenty bucks. Figured why not. Only paying 20 bucks I figured I'd modify it. I added a second motor to it in series. Two odd things I noticed. Both may or may not have been present before I added the second motor.
The first was if I push the engine down a length of track that is non-powered, the lights will flicker and even come on steadily for a few seconds. I even unplugged the transformer to make sure there was no voltage getting through. Almost like some type of alternator effect.
Second, never using Bluetooth to any extent, I figured I'd give it a try. Seems to work okay, but when you throttle down the engine starts to slow down then speeds up with a burst of speed for a few seconds and then continues to slow down. Is this a common trait of low end lionchief w/ Bluetooth? The engine seems to basically run fine other than the speed issue with Bluetooth. And with the remote it's perfect. Just thought these two situations were odd.
