Is this what you call a counter rotating propeller?

And will this fit the DT750?

This will fit the dt750 but you need 4mm drill bit

what is the hole size and how many standart/counter rotating

The hole is 2mm, there are 5 counter-rotating props in a bag. No standard rotating props, that's a different product.

I can't recommend these though, they are a nightmare to balance. Way off straight from the pack. Stick with the GWS ones, much less work!

They're really cheap, but also a lot of work to balance. Out of 10 props, just one was close with the hub, the other 9 were massively unbalanced. Blades all needed some work.

They're also very brittle, and break very easily.

I use these in my quadrocopter - 4 * DT750 and 2*1147 2*R1147. Thrust is pretty enough to carry about 1.6 kg. Quality isn't perfect, not well balanced, but seem to be usable. Sharp edges, I accidentally cut myself while motor was not running:(
