<span style="color: #0000ff"> Yben how you like your hk450 the tail is a real pain in the rear end from what i heard plastic pulley slipping</span>
I encounter that before, I replace the shaft with the original trex shaft with metal pulley, the original trex tail shaft, main shaft, spindle are much stronger than the clone one. I also replace the tail gear to original trex tail gear blue.
