I recently purchased 2 XL motors from Lego direct. I noticed one of the motors has a higher pitched sound, almost a slight grind. It spins up faster and slows down slower than the other XL motor which sounds smooth and stops quicker. Has anyone noticed differences between one motor to the next? When direct coupling motors without a differential one motor will be straining more than the other which can't be good. I am curious if I should contact Lego about this noise and speed variance between the two. -
I wanted to know if anyone has tested the difference between the following setups with V2 IR: Two XL motors with a (3:1) 36 driver to 12 follower or (5:1) 40 Driver to 8 Follower VS. two L-Motors with the same Setup. The reason I ask is because right now I put together a setup of Two L motors running (3:1) 24 to 8 direct output to an axle without a differential. It hauls pretty well. After researching more about coupling motors on Philo's website I am surprised to find out his reasearch shows minor advantages to coupling. When running a single L motor with the same 24 to 8 gearing I had less torque and top speed took longer to achieve. I am waiting for a couple of orders to arrive to test the various gear ratios and motor couplings, I didn't want to rip apart my sets at this time.
