These are the props you need for a 750kv size motor for quad-copters. All needed a slight balance with a bit of rub down with fine sand paper. Dont forget the right hand rotation ones aswell. But I see what you mean everything was in one box lucky no breakables

I love it how when you give a bad review on something, for some strange reason, IT DOESN'T SHOW UP!!!!! I've been dealing with HK a long time. But never has a packing job been so terrible as the one I just got. Everything was just thrown into one bag. No separation or bubble wrap at all. If this is the way it's going to be, I will just paying a little extra and get it from somewhere where the customers mean more than this!!!!

That's not good. I wonder how will my last be when it comes.

Has anyone tested these on a d4023-850kv? What output on 3s?

The 4mm rings are more like 3.5mm. I had to drill mine to fit my NTM 2830S 800Kv shafts.

Would these be better than suggested 1045 used with HAL Hexcopter?

Depends on your motor if it has room for additional load. What motors you plan to use it with?

I'll be using "NTM Prop Drive Series 2826 1000kv"

It depends on if you're planning on using 3S or 4S pack. On 3S you could run the 11x4.7 but on 4S you are going to draw more amps than the motor can draw safely. On 1000kv I would stick with the 10x4.5. If you drop to 750kv on 3S, then the 11x4.7 is good.

I'll be using a 3S 4000 20c battery in the start.
 Jarrah 30 points
In that case your multi will come out weighing about 1.5kg once you add 4 NTMs, 4 ESCs, battery, props, rx, flight controller and associated wiring. So with 10x4.5 props on 3S you will draw roughly 140w to hover, roughly 14 amps, realistic flight time of 9-15 minutes depending on what you do with the throttle! Rough estimates only. It's a good setup, go for it :) I run the 4000mah 3S with 700kv and 11x4.7 on the X666 (bigger than HAL)frame and I get similar efficiency/flight time.

Jarrah, It will be 6 NTMs, ESCs & Props *)

Aah, yes, forgot to look at OP. Oddly enough, even adding 100-150g for each additional arm/motor/esc taking your weight up to about 1700g, because each prop then has less to lift and can operate at a more efficient rpm, it actually doesn't take hardly any more power then the 4 motor setup. Probaby only another 3 or 4 amps. Be wary of the max draw though. If you give it a lot of throttle or a heavy payload the potential draw on the battery is pretty big. I use a 20c 3S 4000mah on my quad weighing about 1200-1600 depending on what I'm doing and if I fang it around that battery gets warm. Perhaps go a higher C rating for the hex 25C or 30C. It will have crazy power, you'll love it. My quad with DT750, 11x4.7 on 3S is already ridiculous, your hex will be mental.

Bought them for my naza kit. This are actually Gemfan coposites... good finish, and pretty well balanced out of the box.

довольно гибкие и бесшумные пропеллеры, почти всегда остаются целыми при крушениях. Из-за светлого цвета видно в каком месте произошел излом. Клеятся дихлорэтаном.
