You will not get it approved as an "e-LSA"

an e-LSA will either be a kit built by a manufacturer who has built at
least one sLSA... or a "grandfathered" "ultralight-like" aircraft...

the RV-3 is niether.

you could very likely build an am-built experimental RV-3 with a 100 HP
engine and the proper pitch prop that you test fly and enter in your POH
the proper documentation that says it does not fly more than 138mph at
sea level on a standard day at your chosen "maximum continuous power"
setting and you may fly it as a sport pilot.

You are the builder, you test fly the aircraft, YOU put those little
color bar on the RPM indicator, yes you could do it, and do it legally.

OR just build a Sonex or Zodiac 601 that's sport pilot legal to begin
with, or wait a bit for the RV-12.

The other is the high end speed limit (138 mph). It would have been
nice if that could have been waived for single place planes

Well, if you really wanted to fly an RV-3, you could probably hang a
100 hp engine and a less than optimal prop and stay under the speed
limit...


Would they let [me] build an RV-3(B) and register/fly it as an LSA or
E-LSA? Or would they be wise to my attempts? Ok, ok ...smaller engine
it is.

If it must be toned down, the assumption is that "Total Performance"
of the RV-3(B) will get (at least)138 mph ... so, instead, let's aim
for super-low fuel burn. Any small diesels out there? :-)

Wonder how Van's feels about this option - hanging a 100 hp engine on
an RV-3? How would they feel about an 85 hp engine + an optimal prop?

Wonder if the FAA has come up against this yet?

What I'd want is 138 mph (145 ...Oops.wink) at the very best gph
possible AND be FAA approved as an E-LSA. (Single seat preferable)
