REFLECTOR: CLEAN SPEED OR JUST SPEED?

[Tom Martino]

Yes, GPS groundspeed point to point, then back again averages out to a little over 230 MPH.

Tom;

 

Only reason to have them is to reduce drag - more speed.  I have heard before that they make little difference.  Now what we'd really like you to do is get good cruise speed data w/o them, and then put them on and see what difference it makes. (Always looking for data:-)).

 

Have you verified the IAS with another on-board source, like a GPS?  Sounds like it is flying real well.  Marrion would be pleased.

Help me out here guys ... I am test flying ... getting more than 200 knots (indicated) at 75% power (and yes, my airspeed indicator, pitot and static system has been calibrated by Denver Avionics).  

 

This speed is without main gear doors and inspection plates on the underside of the wings.

 

Naturally, I want to cover up the wing bolt holes ... but what about gear doors?

 

This may sound silly ... but if I'm getting this much speed now, do I need them?

 

Is there a reason (other than speed) to have them?

 

Any feedback willl be most appreciative.
