Thanks - my problem turned out to be using pins with friction ridges by mistake. Once I replaced these, it works exactly as expected - thank you!

@ozacek From where did you get that manual? I have that exact battery box and remote from Mould King, but I got no manual. Has anyone been able to download and install the android app? I have the same results as @fosamax - I either cannot find the app, or it is not compatible with any of my android devices. Finally, I have opened up the battery box. The main controller chip is unmarked, but it does have 4 of these chips on it (https://www.yoycart.com/Product/590623288557/), which implies that the motors should be able to be driven at variable speeds.

Can anyone comment on the effectiveness of linking the steering to the rear spoiler. I don't see much motion on the spoiler when turning the axle which would connect through to the steering motor (RC version end of step 45, page 153), and the motion is definitely not symmetrical when turning left and right.
