Hi Ed,

I understand you have a 415-G manufactured by Sanders (all E and G models were Sanders).

The Ercoupe Parts Catalog presently sold by Univair and Skyport applies to the Sanders E & G models. I own a photocopy of a Sanders Parts Price List dated January 15, 1954. The trim part numbers it contains correspond exactly with those in the Ercoupe Parts Catalog.

The trim you describe may be the one described in the Forney F1-A Flight and Operations Manual
on page 19:

"The control is located between the contour [bucket-WRB] seats, and an aluminum drive screw actuating a plastic block to which the trim wire is attached compose its basic parts. To the control is attached a one-piece nylon conduit through which the 0.062" diameter
        stainless steel wire to the trim tab is run."

On the other hand, it is certainly possible that a prior owner simply revised the trim system in your bird to mount a Vernier trim knob in the later trim location. In any case, I do not believe any 415-G had the space between bottom seat cushions (or bucket seats) necessary to the installation you describe. Your logs or the FAA CD for your plane should list when the original trim system was
modified to the one now installed.

I apologize for my poor choice of words when I said "...your bird should have the panel-mounted quadrant shown in the Ercoupe Parts Catalog on p. 36, Fig. 23, Item 39." It would have been more correct to have said "...your bird was originally manufactured with the panel-mounted quadrant...".

More than a few owners have replaced their instrument panels, and if I owned an Ercoupe with the "Airliner quadrant" Trim/Throttle arrangement I would likely revert to a Throttle knob like the 415-C or a Vernier one) and might well install a panel-mounted Vernier trim control (via field approval).

If your instrument panel is original, there should be a rectangular hole centered at the bottom (or a patch there) where the original quadrant mounted. I also have original sales brochures for both E and G models which give some detail as to the original panel and trim control arrangement.

If your center-mounted trim was installed with proper paperwork, your mechanic is wrong in saying it's "not supposed to be there". This could be similarly said about a 5" nose wheel and support on a 415-C, but such incorporation of later model items listed in the type certificate are common.

I can't say if a log book entry or 337 would be the appropriate "approval" necessary, but if you like what you have your mechanic (or the one that did your pre-buy ;<) should be willing to tie up any
loose ends as to the paperwork to make it "legal".

Best regards,

WRB

 My coupe is a G model by Sanders With Sanders Data Plate.
 My trim is located between the seats.(Vernier knob)
 I  beleive you may be incorrect (MAYBE)
But obviously the reason I'm asking is because my mechanic says, It's not supposed to be there.
 I am also looking for a Sanders Ercoupe Parts & Nomenclature Manual.
