Hi everyone,
I've finished trying to RC my 42043 and it seems that the PF L motor has issues providing sufficient power to drive the set? I obtained instructions from the creator of this video (https://www.youtube.com/watch?v=BpP_05uxKqs&t=22s&ab_channel=PawełWojnarowski) and also checked PPUNG DADDY's 42043 RC video (https://www.youtube.com/watch?v=O8easq7ueIo&ab_channel=PPUNGDADDY(뿡대디)-LEGOTECHNICRC), both used an L motor with no problems.
Here's a video of the issue: https://youtu.be/J8P13WLPzN8.
As you can see in the video, the motor loses power after driving for some time, eventually being unable to drive at all. The problem is worsened when I try to drive and steer at the same time, it's almost impossible to drive and turn.
I have tried swapping the tyres around, changing batteries, trying a V1 and V2 IR receiver, switching positions of the motor and servo cables, and using a new L motor. But the problem still persists.
Here's a photo of the L motor:
Could it be because of excess friction introduced in the rear axles during construction? Because I noticed when I lifted up the rear axles, the motor spins the wheels at its standard rpm, BUT only 1 wheel on each axle spins, the other is stationary. Then when the wheels contact the floor, the motor suddenly seems to struggle with driving the thing. Hence I was thinking could it be that I built the differential too "tightly"?
Appreciate any help from the technic experts in this forum, thanks in advance!
