If you are using a single 3S 5000mah battery and getting 5-6 minutes then that's about right. I'm using two 4S x 4,000mah 25C lipo batteries in parallel and getting 12-15 minutes and you can do the same. Parallel is the key word here, I do that because 25C is garbage but 50C is alright....

Not to mention that TopFlite has absolutely horrendous manufacturing quality control. The great majority of their magnetic balancing units have an included shaft which is out of balance all by itself. Difficult to balance a prop when your equipment is lying to you.
All of this is a real pity as I love the principle of the TopFlite unit. Just wish they hadn't screwed the pooch.

Yep, I'll second this comment. I have both and the TopFlite one is definitely out of balance on its own. The prop stops in a different spot every time I move the cones around on the shaft :dread:. Not good. The Dubro one is perfect but it needs to be treated with care so you don't damage the edges of the intersecting wheels.
I just did a couple of comparison flights with my night flight hexy setup. First half of the vid is the supplied DJI 10x4.5 props. Second half is a set of APC clone 10x5E props from HobbyKing. The DJI props make hovering thrust at less RPM than the APC clones....consequently I got a full minute less flight time on the APC clones. You can hear the different in the speed of the motors between the 2.

I just purchased a Du-Bro and went through my prop sets. Of 3 sets for a hexa, all the 1045 APCs, all the 1045 GEMFANs and 5 of the new 1038 DJIs needed balance.
The DJIs are presently mounted.
The question is what's the consensus on either adding weight or removing a bit of prop for the balance? I'd prefer to remove a bit of prop since there's nothing to come loose and fly off like a piece of tape.

To Balance the prop I like to sand away material on the bottom of the blade.
To balance the hub I like to add weight. I use hot melt glue I have some industrial black sticks that work very well it is easy and fast, and comes out smooth. Not like velcro and superglue, that can be a bit messy.
The DJI props are so thin, I wasn't game to sand them. I used clear mylar tape and wrapped it around the leading edge of the blade towards the tip. It's still on there now and hasn't needed redoing yet.....about 20 flights so far. It wasn't my intention to keep using these once I got the APC props, but since they burn more power, I'm reconsidering now. Hopefully the APC slow fly props will be better and I can sand those to balance them.

Very interesting! Where did you find the APC E prop knock offs at? I use the APC regular 10x5 prop, not the E version as I feel like those are too thin. The new DJI props seem to be pretty nice now versus the old break-away props they sold

The APC clones came from HobbyKing. They're called 'APC Style' props on there. They're close, but not quite the same material or quality.
I've got some of the new DJI 10x3.8 props coming, so I'll test those as well.

Very interesting, I use those same props and they sound exactly the same. I get about 12-15 minutes of flight time depending on how I fly. The DJI early props and slowfly props were pure garbage but it seems these new ones might be pretty nice. Are they notched for the DJI motors or will they fit any 8mm shaft or what? I use a 4mm motor shaft and I have a 4mm to 8mm adapter for Graupners and such. Thanks.

They are notched. You have to run an 8mm reamer through to install adapters.
if you are new to this and getting a 550 would you replace the standard props with Graupner 10x5 Elektro Prop Propeller Pair or some of the new DJI ones ..
Also putting cost in to this and the chance I will break a few while learning

I was running the APC 9 x 4.7 on a DJI F550 and they were pretty smooth but I put the NEW DjI 10 x 3.8 on and I like them better. the build quality seems to be there and have a much larger hub than the old DJI props. they were pretty darn close to perfect in balance right out of the bag. To me they seem to be shaped just like the Graupners E props but I have never run those.
