Kelly,
  There has already been "air" between the nose wheel and the runway.
  There may even have been some slight amount of air under the mains at some point.
  The airplane gets very light at 80 and felt like it was about to go airborne if I let it.
  But as soon as I pulled the power and the stick back it settles back down on the mains with the nose held off until the speed drops back to about 60.
  Just a matter of time now.

  Jim,
    Hope to hear you have some air between wheels and runway soon!!

  Ernest,
  It looks like you put a lot of effort into this ducting design.
  I really hope that it works as intended.
  Did you check the heat distortion temp of the resin that you used?
  Generally they are around 200F+-25F.
  This would be a concern as the temps could get that high in that area and you would not want the ducts melting.
  The fabric is not a concern as it only gets tighter with temp and the final shrink should be at 350F so 200F will not be an issue.
   
  Last weekend I performed high speed taxi tests for over an hour at speeds up to 80MPH. (0-80MPH in 10 seconds)
  The engine temps stablized right at their ideal temps with OAT at 60-65F.
  My Delta is finally ready for first flight.

fuselage ducting for my oil cooler and one of the two radiators 
completed. The top fabric of the center section looks loose. There is 
no solid structure on the top ribs to keep them spaced properly till I 
rivet the top skin on. It will be pulled tight then. The big opening 
will also be closed up with a section of fabric after the top skin is in 
place.
