I've always used APC props, mostly the 4W series on my planes. This Pro Zinger sounds interesting. Where do you buy them? Are they wood? Wood props can be very fragile and sometimes, and I'm sure I'm the only person in the world, I have a little "squish" on the landing gear when I land and OPPS there goes another prop. But I would like to try a Pro Zinger. If seanychen says they're good. They're good. He really makes those planes sing. I've seen his video of a UCD60. Very impressive.
Thanks,
Barry
