=================================================
Ive been interested in this subject since the early eighties, and would
offer a few additions and thoughts to this posting:
1. The first production ship as the Model 415 with the Erco inverted
in-line engine actually weighed 625 lbs. and was CAA-approved with a gross
weight of 1125 lbs.
2. According to a photocopy of a brochure (of which 4-5,000 were printed
in June of 1942) for the 65hp prewar C-model, empty weight of a
"standard-equipped" ship was 715 lbs with a gross weight of 1175 lbs.
Information available to date indicates ships without "electrics" were
delivered weighing about 724 lbs (about 733 with such options).
3. Both of the above had 14 gallons fuel capacity (one wing tank)
4. The first eight postwar ships left the factory at between 821 and 828
lbs. These ships were now standard with 75 hp, two wing tanks, lights,
starter, generator, battery and associated wiring, and they had the
"steel" main gear replacing the earlier double-fork aluminum units.
5. Original weights available indicate (so far) that between serials 1224
and 3542 actual original weight was down to between 797-800 lbs. These
all had the later forged aluminum main gear, although previous comparisons
have generally dismissed any weight difference of significance.
6. I have actual data on one factory NX "D", serial no. 3700, which test
data lists 815 lbs. as the empty weight. The "D" had the stainless-steel
skin over the nose tank, "airliner-style" throttle and mixture controls
and instrument panel overlay.
7. Since the only difference between the "D" model and the subsequent
"CD" model was the elevator adjustment, empty weights should be identical.
8. My "E" model brochure claims empty weight of "approximately 820 lbs.",
with 85 hp (and added baffling), the "split elevator" and the "low speed
warning cushion" spring installations.
If you enjoy reading "tidbits" like this, all Ercoupe "scholars" need help
to collect such available Ercoupe information as they eventually share
(like this).
Can anyone send me evidence (beyond Sanders' "specs.") that either the
415-F ("E" with fuel-injected C-85) or 415-H (stripped-down G with 75 hp)
was actually manufactured or sold?
For those of you who have the original "as-delivered" sheet for your coupe
in your paperwork, I'd appreciate a direct email to <[EMAIL PROTECTED]>
with your coupe's serial number, date of production (or acceptance flight)
and original factory weight for my airframe database.
