I have used the CMR-type pop-off launch lugs for egglofters and scale models. My experience is that you should be able to give the model a gentle shake and not have the pop lug come off. I usually would tap the top of the lug firmly to ensure that it does release. Not hit it hard, but more than a touch.

One technique I used for certain egglofters and a BT-50 Sandhawk is to make the bottom attachment a centering ring that the motor fits into instead of using hooks. You may have to use more of a standoff from the launch lug to get the ring in the proper position. For the Sandhawk I used a long spruce strip as the backbone of the pop lug. Launch lugs at top and bottom. Wires at top engaged the Sandhawk's scale forward lug and a centering ring at the bottom engaged the motor.
