I did a dumb thing (not the first time)
I hurriedly ordered some spare props and obviously didn't look at the size too well when ordering.
Instead of 10" I must have ordered 12" because I now have 2 sets of them.
What would be the down side of trying the 12" on a standard quad frame with standard motors?
Has anyone got a feel for what is about to happen?
Yes, I have the 28cm arms
Has anyone else tried flying the standard arducopter with 12" props?
@John, I'm running a standard quad, 28cm arms and small motors with 12" props. The reason being I broke
a few of my 10" props. and so to keep my quad in the air a friend gave me some 12" ones to try out. It flys
ok although I find decending from a height has to be done carefully since it does oscillate a lot more than
with the 10" blades. I guess a bit of twiddling of the PID settings might help which I hav'nt tried yet. Also
the motors run a comfortable "warm" certainly not hot. Pirates code..
I am using the Hitec Tx with full telemetry, temperature of all ESCs, height and speed via gps and also RPM for one of the props.
I notice that with 10" props on my home build hexa, the props run at about 5400rpm and with 11" props they run at 4500rmp.
I did try 13" but I got terrible wobble when descending (enough to flip it a couple of times).
I think the lower the prop speed, the less inertial energy is available in the props and this has issues when decending - this might not be tune-outable on the pids.
I find that I get good lift and battery performance when using the 11" blades and my 2814/22 - 760 kv motors or speed 40 amp speed controllers never even get warm.
I would recommend trial and error.
Hope this helps.
Thankyou to all who responded to my propeller question.
What a great forum and an incredibly absorbing project.
There are so many variables, you can never get bored.
