I imagine they are all for sale at the right price.

Fellow Couper's
I probably should not have brought this subject into the forum. To anyone who may have been offended by
the ethics of my query, I appologize.
The post regarding engine conversions/upgrades and a potential disquaification from LSA, piqued my curiousity.
I have inquired on a few aircraft that even though they were the correct model for LSA, through an engine upgrade,
might disqualify them from LSA status.
I have been looking for a swell C or a CD - if anyone has one that is in great shape or knows of one, please contact me.
Thanks
Scott

Hartmut, I've been told by Joe Norris of EAA, one of the writers of the Sport Pilot rules, that the gross weight limit is in the rules to limit the "penetration" of the airplane into a building or other object in a crash. More mass equals more penetration or, in other words, impact. The stall speed is already set in the Sport rules, so gross weight is a whole other factor.

Scott.
As always the main problem is the insurance company for the case something goes wrong.
Other than that , I can only agree. Not many will be able to tell between all the ercoupe models.
As for Stall speed and weight. These are in a direct relation.
The higher the gross weight of a certain airframe, the higher the stall speed. It does not matter if it is a 415 C, D or E. They all stall pretty much at the same speeds when having the same gross weight.
That's why a 415-E would "stall" at 48MPH when loaded to 1260lbs and a 415-C would "stall" at 56 MPH when loaded to 1400lbs. Or vice versa.
I think the ruling of the FAA should have been that all Ercoupes/Forneys/Aircoupes are eligible for the Sport Pilot class when loaded up to 1320 lbs. My guess is that the stall speed is then at around 51 MPH.
I did some calculations - based on the Stall speed for a 415-C, the stall speed of a Coupe loaded to 1320 lbs should be 50.2 MPH. (Unfortunately, this does not work when I base my calculations on the published data for later Ercoupes).
In my few years of flying , I have been never asked for my license by anyone or the type Ercoupe I fly except by my insurance agent.

Hello -
- What are the consequences of flying a plane that doesn't fit into the sport category by a few pounds using a sport pilot license?
- What are the odds of anyone being aware of the difference between a C, CD, D, E etc.?
I am not in favor of breaking the law, but quite frankly, in my opinion, the other criteria of being a sport plane, stall speed,
etc., seems more relevant than weight.
Scott
