I just now noticed that apparently both the Super Cub DSM and LP use a 9x6 prop with mounting hole accessible from both sides (see HZ link and pic below) ...

Therefore, you could use a pusher prop on the LP if it is comparable in specs to the stock 9x6 by BOTH flipping the prop and reversing the motor's rotation. It may be worth a try for your own learning experience to note the difference in traction.
When converting a pusher prop to puller prop any lettering on the prop or the molded stamped diameter x pitch will now be facing outward indicating that you have flipped the prop on the shaft besides reversing the motor's rotation.
