Are Dynathrust props still made? Who distributes them if they are? I know that a lot of people don't like them (judging from all the negative comments I've heard over time), but I have had no bad experiences with the three I have (20-6, 22-6, and 14-8). I like the "scale" appearance for certain planes and am looking for a couple of 18-6 to use on a 1/4 scale Decathlon.
