Deuces Wild battery choices?

Hi All
I'd like to hear what are the great batteries to use in this plane. It's going to be a 4S Lipo - just need to figure out what would be best.... or the best price vs performance choice. There's top of the line like Thunder Power/Evo/SMC ect & then the HobbyCity batteries that are priced much lower.

Here's the setup - Scorpion 3026-10 motors (about 70amp motor) with Scorpion 90amp ESCs.


Thanks
Terry

I would go with no less than a 4000mah 20c pack for your setup.

Re: Deuces Wild battery choices?

Hey - thanks for the reply.... I kind of thought that this thread died from the start.

Here's the battery that we are looking at getting right now: FlightPower Evo Lite 4270 4S 14.8V LiPo
18C Continuous Discharge 28C Burst

It isn't quite the 20c - but pretty close. Does it look like an okay way to go?

Looks like the pack can handle 76 amps continuous. The best way to go would be to run one per ESC. I'm guessing that is probably what you are doing. If you are going to be running a parallel harness to the ESC's with a single pack, then be careful not to run 38 amps +/- per motor and you will be fine.

Yes - it should be a separate motor/ESC/battery in each wing motor nacelle.

Will the BEC work to power a plane like this... or will it take a separate RX battery or UBEC?

The BEC will likely be fine, depending on servo count. If both ESC's have switches for arming the BEC, you'll keep one in the "Off" position, if they don't use switches, you will need to cut the red wire on one of the servo leads coming from only one of the ESC's. Due to the size of this airplane and the amount of servos you will likely be using, I would probably run an auxillary BEC and not the ESC's. If both ESC's don't have switches and do have internal BEC's, you will want to eliminate both red wires on the ESC's servo leads. If they both have switches, keep them in the off position(I wrap them in electrical tape to keep from accidentally arming one). Running dual batteries and a BEC in parallel with one of them will cause one battery to discharge a bit sooner than the other, so a seperate LiPo may be in order, altogether. I usually run a 1200mah PolyQuest/Enerland(1320 TP) on airplanes .40-1.20 size with a bec and a switch between the two.

Your setup would be: Battery->Switch->BEC->RX

This will allow you to charge the receiver LiPo in the airplane and keep it connected without worry of the BEC continuously draining it.
