Need help deciding what prop to put on 750kv

Posted by CyberCrash on February 1, 2013 at 5:34am

Hello guys,

I am using 6x Roxxy 2827-34 750kv on my hexa.

Right now I am flying with 10x4.7 APC props.

I also have bought some EPP 11x4.5 but haven't tested them, because they bend quite a bit and aren't as sturdy as the APC.

I now found out there are 11x4.7 APC available, also.

What would you use?

    Where is your throttle when you hover? If it's above 50%, use the bigger props, if below, stick with the 10's.  If it's far below, then step down to 9's.

    My quad hovers at about 41-42% throttle (you can check the value in the logs) at the beginning of a battery pack, that rises to about 47% or so at the end of a flight.  I like the extra punch I get with having the bigger props I selected.  It flies just fine with the next size down too.  I noticed that I have longer flight times with the larger prop.

    You'll have to adjust your tune a bit when you change prop size.

    Don't get too overpowered, that'll give you problems too.
