I think you guys are exactly right; someone did 750 * 2.2 * 2.2 = 3630. Whoopsie! But with a two-seat maximum nobody will make an aircraft that heavy anyway.
Of course gyroplanes don't need to be LSA; it just so happens that all are well below the 120 knot max speed, all are well below the max weight, and nearly all have only two seats. Actually I would be very interested in a four-seat gyro if one were developed.
It won't be a straight 3600 lbs. weight limit, but it will be a formula of some kind that takes other factors into consideration. It also may allow an inflight adjustable prop, but not with a prop lever, but more like a follower plate such as the Cirrus uses.
Some think that the weight limit increase will be damaging to existing LSA manufactures, but I don't think it will. One of the main advantages to the lower weight aircraft is the Rotax engine, which is most beneficial at these lower weights.
Dan johnson who has been working with the FAA for the past 4 years called his contact when the EAA published the good news.
It will most likely include gyroplanes.
The bad news is Dan published his FAA contact statement to him and it may be a 3 or 4 year process so not as opmistic as the EAA report lead us to belive.
There is no news; you're mistaken. A four-seater certificated Cessna 172's MTOW is less than 2500 lbs. The six-seater 180-knot Bonanza's MTOW is about 3600 lbs. There is literally no possibility whatsoever that the max weight of LSAs, which are two seats and whose key word is *light*, would be as much as a Bonanza. If you want a 3600-lb aircraft you just have to fly something that isn't an LSA.
