Yes, what makes you think otherwise? I'm using it on my scratchbuild foamie with a 1400kv motor.

o que você* tem que se adaptar?

Yes, I used 8x4x3 / 9x5x3 and I must say... it depends. The 8x4x3 I used in motor 2210 and the other in 2215 cause 2215 is stronger than 2210 and my xcopter is heavier than other. I think the 8x4x3 could be ok for your xcopter. * Always balance the props!

I'm running four FC 28-22 at 1200kv now with the 8x4x3 props and Wow! It seems the thrust has doubles but the stability has remained the same! I've not tried the 9x5x3s on it yet. But, with the 8x4x3s the static thrust and the prop stall thrust are almost equal at 41.37oz. and 41oz. respectively with this set up! Video to come!

A killer for both motors if you don't manage the throttle very well. Furthermore, those props wobble a lot at high KV. So the 2308N1100 should be fine. It should produce ~250 gr of thrust so on a tri you will get a total of 750 gr max. Your tri should not exceed the 400 gr all in all...

I'm using this prop with a turnigy 2204-14T here is a you tube video link of it www.link

Foster, click on the YouTube icon below these text windows and past your link there. I would like to see you multirotor.

spinner? you mean motor? I use dt750 hextronik in my quadcopter. Very stable flighy. and there should be 4mm adapter step which is good for that motor.

yes I have this but it's not besser than normal propeller

Hard to find spinners for counter rotating 3-blade. I would use a GWS rubber spinner and cut out three slots* make sure the three slots lay out with 120 degrees angle, or using the propellor as template. Make sure the cut-out pieces have as identical shape to ensure minimal balancing. It is doable but takes a lot of trimming, trial-and-error. For scale-looking's sake, however, this work might worth it.

just use a prop adapter, they fit nicely..

Yes, it will work but is not optimal. I get much better lift with 9" 2-blade GWS props. Hard to find pusher models though..

Thanks for your reply, Hubben. How can I calculate the right propeller for octo? How can I select lenght and picth, is there any guide? Thanks for your valuables comments.

 hubben 300 points

Hi, there are some tools to calculate the right size props. If you search for "propeller calculator" on google you might get lucky. *-) Personally I've found it best to experiment. Depending on the weight of your octo you'll need different props. You want to balance the lift capacity to the weight for best stability and performance. Larger props with more lifting capacity is not always better for your setup!

They work for Quads/Octos, but some report that two-blades will work better for more dynamic flight. At the price of the GWS, I have bought some too. No problems so far.

I Did try these on my quad, but too hard to get balanced. Get better results using some 2-blade GWS props.

Hi, yes it will perfectly fit because it has the same shaft diameter. Here the shaft diameter is 3mm. But in fact neither of the shaf is really 3mm because it is 3.17mm for all the 3mm shafts. Hope it helps.

I have used this 4 set counter and anti counter for my quodcopter with Towerpro motors. It gives total more than 3kg thrust by combining all 4 props thrust. Robust and good quality at cheap price.

How to get the item fast

 rohitdesa 7 points

*akshat: no way to get them fast...you'll have to wait :-( I made a separate order of stuff that I didn't need urgently and asked Customer Care to shift these props to the second order.
