Picked up some carbon APC props to try. 20.5x10, 21x10, and 21x10.5.
21x10 weighs 4.4oz. It's not a wide blade like their other 21x10. I'm thinking it might be a good one to use.
Made a couple changes. Moved the rudder servo forward and also got rid of the choke servo. Realized all I had to do was change the choke position and I could run a wire out the side.
Pipe should be here anytime.
The v2 fourtitude fuel tanks are nice. I like it a lot better then the water bottle type setup.
I got the same Carbon props as well. I've run the 21 X 10 and it performs very similar to the normal grey one, but 40 grams lighter. It may have a little more pull in verticals, but I've only had a couple of flights with it yet.
They also make a 21 X 10PN which is the same as the Carbon 21 X 10PN and that's what I'm comparing to.
