Or if I opt for a Zodiac XL, would it be better to use a Conti O-200?


I think it pushes it above the weight for LSA designation. Check on that.

I'm not sure if your talking about the 'built' version or E/AB version.
If it's the experimental version you can set the gross weight where you
like. Just limit it to the LSA requirement and your good to go. You will
lose some useful load which you can trade off with smaller tanks and less
range if you need the weight.

Could you ex"pound" on this - set the gross weight where you like?

Thanks

As the builder/manufacturer of an ambuilt-experimental you can
absolutely set the max gross weight anywhere you like... Who is to tell
you that a kit that others have built and set at, say 1450lbs is
mandatory for you to do the same.... Of course, a ramp check when you
and your 200lb friend climb out and pull out pull out 200Lbs of camping
gear that's 150lbs over your gross weight will be a problem....

S-LSA and kit E-LSA are regulated as to the min usefull load to combat
just this issue... but ambuilt expermimental is not.

Can a SP built, then fly an ambuilt experimental? I declare it to be

I declare it to fly ...138 mph continuous max power, etc. I declare it to
have a stall speed of...

Simple answer, yes....

You don't "declare" it, per-se, but durring your phase one testing you
establish these numbers and enter them in your POH for phase II flying.

If your off a little... probably no problem.. if your "off" alot..
probably no good will come of it.....

Yes Montred (hey if you can do it I can) ;-)

You can set the gross weight for E/AB where you like. You might/should have
some documentation as to what the pane can actually maxout but you
certainly can set it lower for safety sake.
The speeds are another story. You can't easily 'set' the max continous etc
etc but you could put an electronic (or otherwise) limiter on the engine to
keep the speed within limits and/or adjust the prop pitch/diameter to limit
airplane (or prop/engine) speed. Now if you have a 250 kt plane it might be
difficult to limit it! My plane which I'm slowly (very slowly) working on
original specs are 180 mph cruise (yeah right) realistic most cruise at
140-150 so proping it down with a climb prop takes care of it easily the
problem is stall speed mines about 3 mph high so I need mods to lower the
stall down.
The whole point is E/AB has a lot of leeway!

Also the AMD CH601XL is SLSA (the one Jim Pellien is selling is ELSA)and it
has a Cont O-200 they lost 70lb useful load because of the engine weight
but it still has the 1320lb gross.

Sorry for the rambling post!

What is the useful load expected to finish out at?
