The Webr speed 40 with the tuned pipe turning 18500 with 9-7.5. Covered tank,and servo bay shouldn't have much drag except the side exhaust.
Tell us about the first flight, those are really good colors for the plane, as it can be very hard to tell up from down with the Dust at a distance.
Are you really turning those RPMs with a Weber?? My West 50 turns a 9x7 17400 RPMs
