Found one that had the entire run of "Firefly" on it. I got through 3 episodes before the traffic started moving again....... God, That really was an amazing show.

A 10 metre roll of neoprene arrived this morning.
As did 8 new DAL props, 24 rubber feet for the QAV250, and one of these:



This is the second battery of this type that I';ve bought.
They are a little bit saggy, but the power delivery is EPIC.
And they are very light weight. :>  And heats up much less than the Kypoms..

I think this is my favourite model of battery now.

I';d be interested in any v-droop testing on that battery if you can mate.

v-droop?  I';ve not heard that term before. :>  But I guess maybe that';s the same thing as Voltage Sag?

My experience is that the fresh lipo out the box was VERY saggy for the first 2-3 cycles.

Sometime around the 4th cycle I realised it was now only sagging at the very start of discharge.  For example, most of my lipos sag to 12.0 volts within a few seconds of takeoff, and I feel like that is about normal.  These were sagging to about 11.4... and bear in mind this is following 5-10 seconds of slow-n-steady forward flight after a very gentle takeoff.

For the first few cycles, this sag would extend right to the end of the lipo';s life.  So my Taranis would start screaming "VOLTAGE CRITICAL!!! OMG!!!" and I would land, and the lipo would bounce back to 11.0 volts...  very frustrating!

But 4th cycle onwards, I found that it only sags a lot at the start.  Toward the end, it';s not especially saggy... no more than any other lipo.

So I really find it hard to fault this batteries.  Just to remind, these have power delivery like ****** on the business end of a shovel.  I have not encountered a lipo with this much power delivery capability, and in fact I suspect my 250 is not able to make full use of the power that is on tap.
Also, the capacity is tremendous.  Discharging to 10.8 volts, I found the charger is putting 1700mAh back in.  On a battery rated for 1400, that';s very good.

It weighs 132 grams, although I could trim that down a bit by shortening the unusually long 12AWG wires.
The balance connector is slightly longer than I';d ideally like... about 2-3 inches, I';d prefer 1-2.  It sticks out a bit when I';m flying, it';s hard to find somewhere to tuck it in.  I guess those could be shortened too, though..

It';s a very long and flat battery - the longest and flattest that I own.  I have to shove it all the way back into my VTX antenna to get it sitting roughly overhead the FC.

A final note, these batteries do not get very hot considering what I do to them. =P
I spoke to HobbyRC quite a bit about them, I actually contacted them after the first flight to ask about the saggyness.
They are saying that those lipos need a few charge/discharge cycles to properly get going.
They also said that they have very low internal resistance, whereas the Kypoms had quite high internal resistance.  That explains why the Kypoms got very warm, and these do not.


In summary... I recommend these lipos.  Sagging only occurs at the start of the battery once you';re through the first few cycles.  The power delivery is immense, as is the capacity, and they stay relatively nice and cool.

Do you know if this can take Hubsan X4 props? If not, do you know where I can get spares?

No, I dont think so. I have some x4 props somewhere and will let you know - when I find them.  :hmm:

Do share a link please, still waiting for mine but can foresee spare props being essential ::)

I would be careful about doing that, 10000mah @ 10C gives potential for 100A discharge in abnormal situations.

Somewhere there is a Parcelfarce van driving around with my stuff in it, which is bad enough.

Then I get a text from the wife saying that she has decided to go out and do something unimportant (like have her arm re-attached or something)

It';s simply not good enough

The +-~ markings are on the side of the casing, but to be fair they';re hard to see. IIRC you use the bind port for CPPM.

EDIT: Just realised that RX doesn';t have a casing does it. The negative is the bottom row of pins.

Loads of Dal 5040 Bullnose props and a brace of those Turnigy 10000mAh LiPo to go with the first one that I bought a few weeks back.  The miniMax Hex loves them, I got 20 minutes flight down to 3.7V on the lowest cell.  Beautiful IR on these, being 1-2-1-1 which kind of makes me think they are not 10C at all ...

In regard to the XT90 connectors - I use XT60 on all my kit, so I have made up an adaptor by soldering the respective connectors back to back.  My hex doesn';t pull anywhere near the 60A capability of the XT60 so I';m well within tolerance.   If in doubt do check your own setup with a power meter.

New Dal5045 bull nose look a lot beefier than the 5040';s and feel a fair bit stiffer as well, I wonder if their durability will be as good as the 5040';s

From www.surveilzone.com

Seems like everybody is trying these, like Slobberdog57 said, they';re not as flexible as the 5040s, but also not as ridged as the 6040, so hopefully the resiliency is somewhere between, with a bit more thrust than 5040.

ive had a go with mikes (MP66 on here) and it was very nice to fly. he seems to think its been built upside down though as the wheels are usually pointing heaven ward when he flies his. either that or he';s trying and failing to do touch and goes on recently constructed cricketers changing rooms. hooligan.
