Rereading your original post: you mention sluggish performance when loaded, and being unable to get more than 3500 RPM. You also mention a maximum speed of 29 MPH when running light. What RPM are you reaching when you hit that 29 MPH? You may be able to improve things significantly by simply changing the prop.
Also, at what height is your motor mounted? That is, what set of holes on the motor are the bolts in? Many motors are mounted too low, which also affects performance.
