what battery in 500 3d

[nono]

Can I put in 500 3d a FP 6S 4900 ?
Is there space ?
What the max dimension for battery ?

According to Ralph of Mikado there is room for the 4900/5000 rex 600 battery you speak of.

IMO we need some 25C batts in the 4000-4200 range to get an extra minute over the 3700 w/o adding too much weight.

Can 2 5S 3200mah packs fit in the battery compartment?

[jamesotron99]

yes, because it's the same frame as the 600, which you can run 12S on no problem (apparently).

Evo 6s 3700 here 25c :smokin:

Get Chandler to shoot some new vids Bobby!!

Can't wait to see. :WOW

I am going to run the same system from my stretched logo10. Not so much because it is any better, just that I already have it and it works fine. Z50A-600 (want to change that to a Z50A-800, just don't have the money) and 12s-2070TPX.
If I had about $400 lying around, I would want to try 12s-2500evo20's and the Z50A-800. It would be a tad heavier but should have lots of power to spin the 550mm blades.

Will cant wait my self!!! The new Flight power Evo 3700 amd 4900 25c cells are just insane

I don't understand the 12S 2000-2500mah range setups....small cells do not take the amperage, of course being higher cell count I understand less amp pull but it makes more sense to be in the 6-8 cell range and 3500-4500mah range imho.

I agree completely, it just happened that I got a set of 4 3s-2070tpx packs used for several flights as a test in a Trex-600 for about 1/2 price. If I had more cash available, I would get a single pack in the range you mention. As it is, my logo10 was ballistic so no real drawback either. I do not expect the Logo500 to be any different except that it will be nice to have the extra motor space, the option to use mini or std servos and the driven tail. I will be running 550's on my logo 500 also. :)

[OICU812]

Ahhh IC makes sense for certain. Man we need these things quick! Don't we? HAH! :lolol

[JFGRN]

I'm going to give MaxAmp 6s 4000's a shot. I like the they're nice and light.

PLEASE...whatever you do don't get the MaxAmps packs. I went that route and they are completely useless after 15 cycles. Every heli pilot I have ever talked to that had MaxAmps has said the same thing.

You don't have to take my word for it though. Buy some and 2 months later you'll be buying some quality packs anyway.

hey , a set of 550s along with some 6S packs , this thing is ganna rock

I think you are assuming that the current used for both setups is tha same, and that is just not the case. For the same power, a 12s setup will use half the current of a 6s setup. What's more, the heat losses ae a lot less as well. These losses rise as a square function of the current, so the higher the current the faster the heat rises. The motor's resistance rises as the temps go up, which means the torque goes down, and you get more bogging.

The bottomline is that a 12s-2000 setup will have gobs more power available than a 6s-4000 - based system.

its a fine line to find in a HV system, weight is one of the issues that will stire others away , but what I also like about it other than what Gary said , it has a different feel to it too , torque to the cyclics , another way to look at it , lets say your logo runs really well at a 6s 12c power system, HV would hit maybe alittle more than half that , so the voltage stays more consistent,

just to let you know that there are flightpower evo 25 4350 cells, only 90g heavier than the 3700. both 6 cell packs.

I got the amperage part, I run HV systems as well, I guess my Q or point was is what kind of flight times can a person expect out of the smaller mah cells and what kind of cycle life?

[Motions]

It's a matter of power not just capacity. A higher voltage setup will be MUCH easier on the batteries and your cycle life will increase quite a bit.

Example:
22.5V at 900W is 40A
45V at 900W is 20A

The power stays the same but the current draw is cut in half.
