Ah too bad.

Thanks for updating us courierguy.

What made you think it was going to be heavy?

A lot of "stuff", not just my opinion either. Cost to manufacture all those parts may have been an issue also, just a guess on my part. Probably mostly because they are staying pretty busy with their full sized Cubs also, maybe it was just more trouble then it'd be worth to the company.

Take a look at all the "cub clone" LSA type airplanes. They're all heavy, and what was described for this airplane would make it even heavier. As I noted earlier, using the Rotax engine saves a good bit of weight vs a Lycoming, but you also give up HP as well, compared to the Carbon Cub, etc.

Consider the LS version of the Bearhawk. The prototype was built without an electrical system, to help achieve a reasonable empty weight. And, it's a bare bones plane as well.

This is kind right. From FAA FAR 1.1:

(2) A maximum airspeed in level flight with maximum continuous power (VH) of not more than 120 knots CAS under standard atmospheric conditions at sea level.

The question then is what is maximum continuous power and who defines it.

"Rated maximum continuous power, with respect to reciprocating, turbopropeller, and turboshaft engines, means the approved brake horsepower that is developed statically or in flight, in standard atmosphere at a specified altitude, within the engine operating limitations established under part 33, and approved for unrestricted periods of use."

Who defines Vh?

I don't have the citation at hand, but my recollection is the manufacturer defines that. In my Cessna T210, the take off power was somewhere around 300 hp but the maximum continuous power was 285. Carbon Cub uses this in their LSA so they hang a big engine on it and then say you can't operate at more than a certain percentage of power after a certain time.

As an upshot, yes we care limited to 120 kts Vh but we can do 140 kts indicated at altitude and we can hang a 200 hp engine on the plane as long as we (the manufacturer) establish Vh which meets 1.1.

At least, that's how I think it is.

The guys with the hot rod E bikes (as in 110 mph and 11 sec. in the 1/4 mile) use similar tricks, interpretation s let's call it, of the fed. rules regarding their bike rides, that cracks me up, where there's a will there is a way!

Anything happening with this project???
