Early Huina 1551 vs new 1551 

My early release Huina 1551, it has a few mods but still has stock boom gearbox and electrics, just added some cheap actuators to get more movement on the arms.
Next to and compare the newer boom gearbox of the newer 1551. The new one seems have better boom gearbox as the early one has a small delay from press remote to it move.
Think I prefer the livery of older model though.
