What would it take to get to 1320 gross? There must be folks that tip the scale over 225 and might want to carry a bag too.

How is the corvair engine in comparison? Performance, endurance, approx burn rates etc.

The big issue with using the 0-320 is the useful load.
The weight of Panther LS (long wing) in its lightest form (small tail wheel, light wheels and brakes ,no elevator balance ,no lights, auto pilots ,interior etc), using the lightest version 0-320 with light wood prop etc will weigh at least 825 lbs painted.
for comparison ,currently unpainted 0-320 powered Panther LS empty weights range from 821-851 empty.
Assuming you build super light and have a 825 lbs airplane ,at 1115 gross weight you will have 290 lbs for pilot fuel etc.
SO a 170 lbs pilot would be able to carry 20 gal off fuel.The big thing is that at 138 MPH "lsa max speed"
the 0320 will have a very low fuel burn ,likely under 5 gal per hr so you would have a decent endurance.
This was a very optimistic example. If you end up with a 865 lbs Panther, And weight 220 lbs...... you can carry 5 gal of gas.....
I should also note that SPA does not officially "recommend" or support the 0-320 (or any of the heavy engines) as power plants for the Panther LS.

Apparently Buddy and Will are still looking for scales. If you intend to paint, add about 25 lbs.

Is there an issue with staying within the LSA criteria given the extra weight of the 0320?
