Greetings,

 

I had a very optimistic day for my rev-2 upgrade.  First, I weighed most of the large items, and got an estimate of the difference in weight between the turbo version, and the new NA arrangement.  It should be about 54 lbs lighter!  All this weight off the nose is also great, since I was way nose heavy before.  Calculations show that the CG will move aft 2", which is just perfect!  I really couldn't have hoped for any better results. 

 

I also managed to get the initial fitting of the new cowl done, so I can concentrate on fitting evap cores, intakes, and exhaust.  This is actually the fun part, especially when folks drive up to the hanger and rave about the looks of the new cowl.  It's amazing how good a stock cowl can look :-)

 

Cheers,

Rusty (Motivated, but still a ways from the second first flight)

 

 One thing that I've learned is that an ounce here and an ounce there and My bird's initial weight in was about 120lbs heavier than the average.  I didn't really think about it until someone suggested that would be like building one to the average weight and then adding two sixty pound bags of cement under each wing.  Brought it into perspective quickly.  Weight kills performance, it mostly affects take off and climb performance.  Many folks believe it doesn't have that much effect on top speed,naturally any addtional weight of course requires a higher angle of attack to create the additional lift.  But, with the RV's barn door wing, even a little increased incident from the optimum (design weight) adds quite a bit of drag, and so will (at least in the case of the RV) cut down on your top speed.

 

   So, you're doing good Rusty.
