Dear Sir. I have been running a DLA 112 sense early spring. I just had a prop explode on the ground, and need a new prop driver. The part that has the magnet in it. Can you supply the needed part? To see the DLA 112 fly a scratch built AirTractor 401B, click on the link. The plane weighs 55 LBS. and has a wing span of 132 inches.http://www.youtube.com/watch?v=O_xJKmfRDZk
