Hi folks,

 

I was ordering a new load of gemfan props from flyduino and I noticed there was a new type of prop available. It's the 10' graupner clone as it's the same shape and pitch, but much much cheaper :D.

I ordered two sets and am going to try those on my Iconic-X when the weather clears up.

Anybody else tried those props? Just want to share my experience with it to you guys in this topic. I put them on balancer yesterday and 3 of them were totally in balance. I had to balance the 4rth one, which was just a little bit out of balance.

Interesting stuff, I also use Gemfan props.

I must give these new ones a try sometime.

I like graupner props, but I hate breaking those as the costs are pretty high :D. This would be a great alternative if these turn out to be good.

Graupner's aren't always perfect...   I had to balance 2 out of 4 of the 9" blades I tried a little while back.  I've had $1 GemFans give me that, sometimes.  They just aren't as stiff.

yes these are less stiff than graupners, but the thing I like about the graupners is the very nice cutting through the air. A little bit less thrust than other same size props, but much easier to iron out the vibrations when well balanced. I hope these new gemfan e-prop will do the same as the shape is identical.

 

I did have to balance graupners in the past, but those are not that much out of balance like the other props I've had.

Thanks for sharing, Boris. You can buy a grip full of these props for the price of of 4 Graupners!

I managed to find some carbon props on Goodluckbuy which are the exact same profile as the Graupner props. 

 

You can find them here

 

And they sell them in 2 pairs!! they are dead cheap!!! Buying a set of 2 pairs is still cheaper than the Graupner genuine props and they are carbon fiber!

Yup had a gentle flight with those today and ot felt just like graupners....i swear. The props felt really smooth. Will see if I can post a vid tomorrow. I was also testing my new 4s setup and it was cold, but will push it a little bit more tomorrow and post a quick vid.

Nice find garbungel.  Video looks pretty smooth, I just ordered 4 sets.  At the very least I will use these when flying without the GoPro.  Last crash I had took out 4 Graupners, Needless to say I was not happy.

I searched around and wasnt able to find any other place.  The Gemfan website doesnt list them either.  Shipping wasnt that bad to the US, $13 and change for tracking.  4 sets and shipping was still way cheaper than 4 Graupners.

I don't know. It seems not, but there is not much to understand I guess. You get full set of props for the prize of one graupner. Everything else is like any other webshop :D.

 

Flyduino is one of the most respected multicopter webshops in Europe, cause they sell warthox frames :D. I think they sell the most gemfans on the world and always have the newest models.

 

EDIT:

That's great....I always used the german version :D.

Click the German flag at the top, Johnny. Open a drop down where you can choose English.
