I did many hundreds of landings in a D without any problems. I didn't have to use full nose up trim (even a little old lady can pull the yoke full back in a Coupe - I just used two fingers to overcome the trim for the flare). I did in fact bleed off forward speed by gradually pulling back on the yoke during the flare (6" above the runway) to reach the limiting stop just as I touched. If you lose power late in the approach in a D model, you just keep your airspeed pegged where you wanted it and do your flare a bit closer to the end of the runway than you had planned. Since a D should no more be flown down the final approach at full up elevator than a C should be, it just doesn't make a darn bit of difference which model you have for this purpose. The only time I was threatened by the fence at the far end of the runway was when the [EMAIL PROTECTED] Goodyear brakes popped a clip as I tried to stop at midfield for the turnoff. Even then, I did a U turn at the end of the runway and stopped in the weeds without damage. I would assert that ANYONE can learn to fly a D model with full safety. At the same time, I think the FAA should grant a blanket STC for installing the split elevator on any Coupe that doesn't already have one.

Ahh, the clarity that sleep brings...I said (last night): "...with trim in "cruise" position (that's right), a good stabilized is gliding 70 mph over the fence with the throttle set for 300 fpm sink. SLOWLY closing the throttle to idle while SMOOTHLY bleeding off airspeed by pulling the yoke back increases the angle of attack to arrest the decent slightly nose high with the mains about 6" off the runway and the yoke all the way back. From there the bird smoothly settles as it slows; first on the mains, as it should." I should have mentioned that this works for 415-C and CD spec. coupes. The "D" Model does not have the up-elevator authority to bleed off forward speed this way...it doesn't land well without full "noew-up" trim...which means if you lose power late in your usual approach you land short with forward progress possibly arrested by the wrong side of the airport fence! The 9º up elevator limit on the "D" is a safety hazard created and perpetuated unnecesssarily without meaningful purpose by CAA/FAA bureaucrats! The only time I tried to demonstrate this technique to a Forney owner (equally applicable to any "E" Model or later with the "split elevator" and "Low-speed warning cushion" (spring) in the system, including Alons, we "arrived" still in my 300 fpm decent! This "first encounter" with the additioal force required to overcome that spring delayed my necessary application of same just long enough for firm ground contact, so I don't know if this works on these coupes with practice.
