RV-3 registered as LSA

[Keith Rush]

No. Not trying to push any LSA limits at all. I'm just starting on my sport's license and full scale experience. There is so much to read and learn, which makes it very exciting. I was looking at the weight of the RV3 as compared to the 12, but forgot about the speed restrictions for LSA and that it needs to be designed as LSA. Just trying to learn from everyone here so I appreciate the responses. Probably shouldn't be looking at planes at 2 am.lol..

I will ask about the engine choice. Would a Rotax 912 or the new 914 turbo be an optional choice instead of the O-200?

Like I said, I'm just information hunting. I have no one close by that Flys an RV to talk planes with.

Thanks,


Keith

Honestly I think the Rotax would present a weight & balance problem. It's really light for an aircraft designed for a Lycoming.

Mel,

Would you be available to chat a few minutes about your 6? My number is 757-362-7120. Look forward to talking with you.

Thank you,

Keith Rush

Not only that, even for Lycomings, the RV-3 plans are nearly nonexistent. You'd be surprised at the primitive level of the kit compared to some of the other RVs. There's no FWF kit for example, regardless of engine.

You'd be entirely on your own.

Dave,

Thanks. I have been following your build.

The RV-12 was designed around the 912ULS. Other engines have been made to fit, but the modifications required are not trivial and at the end of the day, you still have to meet the LSA performance parameters to be legal. If you put 125hp or 140hp in an airplane that has the structural strength to take only 100hp, you become both aircraft designer and builder, and very few kit-builders are qualified to be both. While it's always fun to play around with ideas, a stock RV-12 is as good a performing LSA as you'll find anywhere.

I have a weak motor and my 3 is very fast.... Way past the LSA rules..

Robin,

I know I'm beating a dead horse, but there's not a good football game on right now.

The speed limit on any aircraft, LSA compliant or otherwise, is the Vne.

The speed under a specified set of conditions isn't a speed limit.

What's the maximum continuous power on your Corvair?

If you were the builder, you could put a restriction that says,

"Full power to only be used on take off and landing, else RPMs limited to 1800".

There. LSA rules complied with. My -4 stalls at about 45. Couldn't be that hard to get a -3 to comply.

Carbon Cub:

"180 Horsepower for takeoff and climb up to 5 minutes - 80 Horsepower for continuous operation. It is the pilots responsibility to operate the aircraft in accordance with the pilot operating handbook and aircraft placarding. There is NO governor or limiting system that controls the engines power settings."
