no, you need to change the spin of the motor to change the direction of the flow (change the position of motor plugs AND put the prop upside down) *)

I am using it for a quad in X configuration so the motor will be spinning in the opposite direction. So what you are saying is that I can put the prop upside down? I have this prop here and by the design of it it looks like it should spin CCW when right side up and upside down :( Am I getting this wrong?

You need a counter rotating prop I didnt understand that it was for a quad sorry. Anyway I m not into quads but I think you need two regular rotating props and two counter rotating ones than you put the two regular ones opposite eachother and the same with the counter ones in order to fix the torque of the motors (sorry if it is a bit confusing I m a student from switzerland and maybe my english is a bit tricky to understand) Hope this helps *)

Your English is perfect - don't fret about it :) Thanks for your help - I guess this one won't do for a quad..

What prop size do you need?

 gilcd85 8 points

2-3''.. I ended up using the 3x2 Propellers (Standard and Counter Rotating) (6pc) from HK. They are made for smaller shaft size and aren't too well balanced but at least they come CW and CCW :)

Good question, I am also wanting to know what shaft size this will fit on.

The hole is around 1.3
mm so it will press fit a 1.5
mm shaft

Someone in reviews section said it's 1mm. So ?

A drill bit measuring 1.295 mm slides through the hole with no slop and also no friction. Another drill bit measuring 1.38 mm needs to be pressed in with enough force so that it will stay on no problem.

Its just over 1mm and i managed to enlarge it to almost 3 mm without an issue.

It's about 1.3 mm so don't expect using it press fit with the 2 gr brushless motor... LOL

Hello people .why give a guess answer, after john just gave exact factual measurement of the hole, using drillbits clearly marked. Its a 1.3 mm size hole..... too many people hoping to get credits .... all you do is confuse all others. Please stop it. If you dont know let the next person who does , answer the question. Thank you
