Larry,

  

 That is interesting that you lost airspeed  by completely enclosing the fuselage?  Did I read that right??   

  

 You'd think that the enclosure would clean up the  aerodynamics and increase your top speed.  Does anyone else have any  experience or data with this?   I am currently building a rear  enclosure for my Firestar to help gain a faster airspeed, or will I lose  airspeed from it?

  ..... . I did find after I got home and  went flying with John H and W that after taking off the rear wrap around part of  the enclosure that I lost about 8 MPH by having it on. I couldn't have done  without it on the trip though, I needed something to hold my stuff in the  plane.

Hi,

     After flying better than 2000 miles  with the enclosure on the rear on the trip, I am positive it  wasn't a fluke. You see when John H and W as well as Roger got here, we put in  better than 6 hours flying all over the area here. Head and tail winds of course  mixed. My ground speeds were 6 to 8 mph faster, and the temps were still  reasonable inside with the heater on, since the air seems to be pulled back into  the cone of the enclosure. I know that I can smell gas when I refuel while I  fly. If it were me and I decided that I wanted a rear enclosure, I would make a  serious effort to keep it as clean and aerodynamic as possible, every thing  tapered to the rear, including the area at the rear of the cage. I  would still do a before and after test to see if it was worth it. The picture  shows how the front enclosure looks.

Hi Tim,

 Sorry but the answer is yes, I fly slower with the full enclosure then when  I fly with the half windscreen. I can't figure it out but it's  true.  One of my flying buddies has a Challenger with a  582.  When I fly with the full enclosure I have a hard  time keeping up with him but when I have the half windscreen I have no  problem staying with him. He even commented he had a hard time catching up to me  one time when I only had the half windscreen.

  

 Regards,

 Will Uribe
