If you want to get rid of the whistle round of the tips and add one more blade.Just have 2 blades causes a vortex at the end of the blade.So 3 works great.If you are have a over voltage problem i beleive i have solved that problem.I will post it on my channel when i complete it.

@maguyver1969, ok, what you suggest make sense, however the prop is one peace of wood, so i need to make a 4 bladed insted and insert them together at the mid point.

looking forward for you update

Scary it was, i think the tips sound is a normal result.

Looks like a sweet prop. Blocky section on blade tips probably making the whistling noise. Curious why you left the tip trailing edge blocked, for strength?

[emagnets]

@thrundar, for no reason i left the tips on. or maybe i figured that most aircraft have winglet to help improve wing performance, so why not leave them there!. i am not sure if they are helping, i do not have the eqiupments to test that theory.

Funny, the wood blade I cut made that exact whoosing noise. Scary!
