  When I first start an engine I run it just long enough to set the timing and then I point it down the runway, throttle it up to 6500 rpm and takeoff, the second takeoff is usually off water at 7000 rpm and with nitrous.

I have a friend who bought a new engine form "Hayes Rotary" up here in Redmond, WA.  These guys are very knowledgeable guys.  They told him to keep the RPM's under 4000 for the first 1,000 - 1,500 miles to allow the engine to "break in". 
 
I've never heard of this for rotaries. That represents about 20 hrs of running before first take-off in an airplane (assuming more than idle RPM). 
 
Is this needed?
