Hi Al, 
 
        I'd be interested in learning your MPGs if you could rig a weight shift fore/aft like the deep stall recovery device.

regards, Jeff

trying to keep us in the dark Al? :-)
 
No; I just didn’t want everyone to know about my bounced, crooked takeoff.  But, darn; now I’m going to have to explainJ.
 
The runway at my airport was lengthened on the south end by 1000 ft or so at some point; and there is a ‘bump’ and the junction.  If 36 is the active runway, that’s about the point where the plane is getting ready to lift – so the bump puts me off the runway – but it settles back down; and with just a bit of cross wind – well you get the picture.  So that’s what happened Sunday when Chuck and friend came to have ride with me.  No big deal really.
 
Now, on subject - I can generally get 21 mpg at about 160 – 165 KTAS at say 8500’.  Now I’m motivated to see how much more than that I can get.  (I have a mpg readout on the engine monitor, so it’s easy.)
