As I understand it, a 415C with a C85 that has been converted to a 415 D (I
guess it would be called a C/D at 1260 lb and 9 degrees of elevator) can
be further converted to a 415E by changing the elevator to the split
elevator and resetting elevator travel to 20 degrees up. This I believe
gives you 1400 lbs., etc,etc,

I hope I don't add to the confusion. I don't know a whole lot about Ercoupes yet but I have a few books that do.

I believe the only 415-C/D models were made in the Erco Factory, they sold 368 415 CD's which had C-75-12 engines.

Mod 415-C models with up rated C-85-12 engines can be modified to 415-D by: (Aircraft Spec A-718). However, this does not make them model 415-C/D
The 415-D modification consists of:
1. McCauley 1A90CF7148 propeller
2. Limit elevator travel to 9 deg. up
3. Verify elevator trim tab per Erco drawing 415-31245
4. Mark all flight instrument limitations per 415-D manual
5. Placard per NOTE 2 of aircraft spec 787
6. Modify main and nose gear piston orifices
7. New mod 415-D flight manual installed in aircraft
8. Install "NO SMOKING" placard in cabin
9. Install new model 415-D s/n plate, date of conversion and type No.
10. Install S.S. upper skin aft of firewall (Erco dr. no. 415-31245)
This is the modification that increases the Max Gross weight from 1260 lbs to 1400 lbs.

The split elevator is a separate modification and increases the elevator up limit to 20 degrees which apparently can make the 415-D land a little softer.
