My current Traxxis 45 has no problems with the tiller.
The first one that Amazon sent me 1) didn't work in reverse; probably a bad solder on the circuit board and 2) the tiller was near impossible to put in a raised or lowered position; it extended and retracted fine, and rotated fine, but to move it up or down I thought I was going to break it. I returned it to Amazon and they sent me a new one FedEx next day delivery. The replacement motor has been fine on all counts.
