RE: Hobbistar 60mkIII
Hi there! You knew you couldn't stay away forever!
I just sold my MKIII but I had the stock OS 65 LA on there and it had great power and great vertical, even pretty quick grass field take offs. I was using a 12x6 Master Airscrew prop and it was a blast to fly. I personally love the sound of an engine connected to the front so I would go with the Saito, but that is just me. The MKIII was a tank, I'd opt for the torque of the Saito.
Either way, have fun!
