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?
Thanks
John

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.
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.

not sure if you can damage the motors on these... but I would guess that it will be fine.
