Britbrat:
The Tower Hobbies 75 certainly doesn't sound silly to me. I run one with an MAS 12x8 at 8600 feet above sea level, zero nitro, and let me tell you, that bad boy boy really hauls *****. Love it !! Have a 2nd one NIB waiting for a plane. Totally realiable ... and comparatively inexpensive. I'd like to see it perform at or near sea level !!!
