Hello Jean !

	Glad N140JP is back in the air where it belongs. I have a few
questions:

1) How much top-end speed did you lose with the vortec generators ?

2) What kind of computer program did you use to create the sketch named
"rudder horn ass,y.001" that you attached to your note?  This will help
us read it: I've tried it as a "bitmap" (.bmp), a jpeg (.jpg), a winfax
document (.fxd) and have not been able to read it.  

3) On the additional spring: do you mean you added a spring in the
WINGLET to counteract the higher resistance of the 3/32 cable in the
nylaflow (as Alan Shaw had predicted) ?

4) Are you going to replace the left gear leg with one that matches the
right?


	Be careful with those Vortex generators on your canard: you know what
happens if you stall your main wing before your canard !
