Ewen Rankin replied to nick rymer's discussion Good wind resistant drone
"The 8300mah are just in 3s and I have 4500mah in 3s. All my 4s & 6s top out at 2200mah which isnt giving me the flight time but yes, I need to invest in bigger batteries
I will get there tho

"Hi James. I find that its the gusts that influence the stability with the larger the prop diameters. I've used a large number of props including 2 blade and 3 blade. In a hover, smaller props with higher RPM have move a lot less in gusty conditions…"

"Hi Nick
Living in the UK, my thoughts for what they are worth is that the props seem to give the biggest headache in wind. 
I have a slowfly long duration quad and hex and the larger the disk, even at slower rotations, the more the wind hits it.

Ewen Rankin replied to Don H.'s discussion How do I increase horizontal speed?
"Hi Don
The thing to remember is that your Quad is pulling air through the propellers to make it move in any direction. If you want it to go faster, then it has to
a. Increase the speed with which to pull the air through
b. pitch forward to increase…"

"I dont KNOW the answer to this, but I doubt that the package will be returned.
The import duty will have been paid by Fedex and they will want that money back, and invoice to you will already have been created.

Hi ChapsI recently asked for help for screwy behaviour of the APM board, but after some digging, it turns out that it was the Spektrum DX6i Transmitter which was causing all the issues.I was getting erratic flights and crashes but when I moved to a…

Sorry, last stupid question...How do I tell which version is o…"
