I'll get to 'em soon... Actually I have 1 of 3 repaired then forgot about the other 2 comletely. After lookingat them on Sun. I see that I have to get a replacement impeller for one and 2 new props. The repair is making plastic blocks, glueing them to the body and cowl and attaching the 2 with a zip tie. Silicon won't hold... been there, seen it fail....
