I have two, unrelated questions about the propellers on the Tinyhawk.  First, the Tinyhawk II seeems to throw off propellers with some regularity.  Is this the experience of others?  I have dealt with it pretty well since the motors are not drilled with screw holes, but, If I could avoid it I would.  Any suggestons?
Also, I have some three blade Avan propellers from the original Tinyhawk.  How would it affct the Tinkyhawk II if I replaced the four blade propellers with the three blade props?  Would it change the flying characteristics?

you an try this;

sure it would change the flightcharaczeristics; probably the tune of the quad wont work, generaly 4blade to 3blade should give a better topspeed but less torq... efficiency should be better... but it depends on your motors and settup. just give them a try ;-)

I have the Eachine Trashcan and the stock props were always coming off. It seemed the slightest crash I was looking for them. Totally annoying.

Get these. They do not come off.

I’ve found that I have to check the props and camera on the TH2 after every single flight. If you press the props back in after landing (or for me - crashing) the props stay on.
