Default Found some Graupner 12x6 finally!!

Electricwingman in Europe has them. ( http://www.electricwingman.com )

I've been craving to test these on the Avroto 2814-11S with 4S.

They have them for 12 pounds sterling, which is about 18$ a PAIR!

I've ordered 9 sets to test on both my Avrotos and on the MK3836 on the Quad X4.

I'll keep you posted when I get them to see how they fare.

Anyone knows if there's anyone in Canada or in the US that can get them or ideally, stocks them?

I might have a set for sale actually as I've ordered some 15" props to go with my H6 950mm.. (oops, did I let the cat out of the bag?)

Since Graupner went bankrupt and got themself bought back by another company, they discontinued all props.......

By the way, these props give me 1 more minute of flight time, and make the motor run slower, which makes the craft run muuuuuch quieter.

I love them so far!

Keep in mind that you need powerful motors to run these... (more than 300W capacity)

same Avroto motors as you...should work fine - yes? I'm using Plush 30A ESC's but will be buying some flashed 30A blue series HK ESC's this week. Any problems with the motors or ESC's overheating with the bigger pitch?

Not at all. They work like a charm. Although i'm not in hot weather, so unsure if they would warm up in hot temperatures..

Also, check these out:

I like them a lot because they are 6S capable..

Well, I got a full set (3 pairs) of unsealed, and a set that is installed at the moment so 6 pairs total.

I'll see, as I want to compare them to the 15x5.5 CF that I ordered. You're first in line to get them!
