Just now I called APC and spoke with the engineer at Landing Products (APC) and was informed that the 21x14E indeed has been discontinued.
The reason is that the 21x14E was incorrectly labled as 14 pitch.
It is actually a 13 pitch.
The same
prop has been re-labled correctly as 21x13E and is in production.
So......order the 21x13E and you will get the identical prop as the 21x14E that has been used all along.
Ihncheol....I'm still trimming the Nuance so I'll probably miss those contests.
strange..... it has been on the marked for years..and they had problems whit vibrations and what I heard from a friend this is not an issue with the 21x13..... but I think I most probably will go for a high rpm motor and smaller prop..but still thinking
