That's interesting news. When did they decide to get back in the big prop business? They exited that business a few years ago because of unexplained blade tossing on some of their larger sized props. At that time they said that 18" diameter was as big as they would make.

This is still on their website:

Due to popular demand they will continue to make the 18-21" props. They discontinued the 22" and large props


Two reasons compel this decision:

Manufacturing resources need to be refocused on the emerging electric motor market.
Some large diameter single piece propeller failures have been reported in the hub area where predicted factors of safety are believed to be rather high, based on both structural analysis and dynamic impact tests. The reasons for the failures are not adequately understood. We speculate that the failures are probably caused by fatigue induced by unusual resonance responses. The latter is, of course, completely beyond Landing Products control, given the large array of fuselage and engine mount characteristics in use. We do not believe that there is an inherent problem with the large propellers, based on wide spread use over a long time. However, the occasional failure creates a risk to the APC reputation that we are not willing to accept.

We regret the removal of this well accepted product line from our inventory.
