Anyone read that little tidbit about some manufacturers giving the wrong name to their Extra models in the latest Model Aviation?

There is no such thing as an "Extra300XS."

Two thoughts:

First, what should the name be for the Sig model? I assume Extra300SX? The control surfaces on the tail sure don't look oversized to me, though. But it's not like I got a ruler out and did a scale examination.

Second, and please bear in mind that I don't know IMAC rules, but since the airplane is improperly named, and if you have the 300XS graphic on the fuselage, would that somehow make it illegal at an IMAC contest?

It is indeed misnamed, dont know about the other.

Or how about the AeroWorks (& others) who name a plane a "330".

I thought the Extra 300S originally had a 300HP engine, hence the "300" in the name. The 330 was modified with a 330HP engine, but 330 was never a factory moniker, it was added by the owners to designate the upgraded engine. If that is the case, according to P. W.'s website then hers would actually be an "Extra 350" (350HP)... hehehe.

The "X" suffix denotes eXperimental, since the upgraded engine was non-FAA-stock-certified. So the correct designation, as far as the manufacturer is concerned, would be Extra 300SX, not XS.

If I am incorrect here please let me know so that I do not pass out bad info.

If it's XS then that means Experimental and SX means the final version.... And chances are, you won't find anything on the experimental planes.

I also heard that the 330 was a 330 because some guy put it on his plane..
