Hi,

     

       My new Lightning, kit no. 162, performed flawlessly on Saturday       afternoon when we loaded both of her wings with 40  concrete bags,     30kgs each which       equals 2643lbs. Thus we simulated a load of 3.8g(at)720kg or 1586lbs       GW

       The designed max GW of D-EGFL (which will be her registration) is        700kg (1542lbs).

       If need be I can increase the MGW without  a new test.

       

       The pic shows the golden moment when the forklifts were lowered       and the whole weight sat on the unsupported wings. You can see the       wing bending! We made the test  in a construction materials warehouse,     the same place where I tested  D-ELIY`s wings, so we had  bags to     spare !

     

     At some  in the future the then completely assembled D-EGFL ( read :     Gerd`s Flash!) will have to undergo further load tests of elevator,     engine mount , landing gear and fuselage ( we do this in one go!)     and vertical stab. A static thrust measurement  is also mandatory. I     look forward to this one: I think the ULPower 390iS and the GT     constant speed prop will give me some realy good pull!

     

     Gerd

Hi Gerd...very cool and very scary!

  

 I am building kit #158  (taking my time) and am putting in an UL 350is.  Nick said he was going to send me, or ask you, for some pics of your last bird with the UL and how you modified the cowl.  Never got anything... not sure he ever asked you.  Could you please send me a few pics of your cowl mod and any other tips you  may have for installing a UL on a Lightning.  I know I need to plunb a return line to the wing tanks..have a plan for that.

  

 My build log is here:

 My Lancair ES builder's log is there too.  Have a peek!

  

 Thanks!

  

 Gordon

Gerd,

  Thanks for sharing your wing load demonstration.  Very impressive.  I hope all continues to go well.
