Post Questions about battery, GPS, transmitter.
Hi, team Quadshot!
I look forward to my Espresso!
A few questions.
Which battery do you recommend. Where is it available?
Can I use the JR DSX9 MK2 2.4G DSM2 Transmitter w/RD921 Receiver (Mode 1)?
Which GPS module do you recommend?

Hi, I would also love more info on the battery before my espresso arrives all I can see is that its a
3-cell lithium polymer battery
No indication of voltage/size or perhaps places where it can be purchased.
Thanks

hi
Maybe I can help you with your battery question. You can buy any 3 cell lipo battery. They all have the same voltage 11.1 volts. As for the size it is mentioned in the quad-shot wiki (http://wiki.thequadshot.com/wiki/Quadsh ... ifications) the battery bay is mentioned as (Battery bay: 125mm L x 37mm W x 24mm D (4.9in L x 1.45in W x 0.95in D) ).

http://www.hobbyking.com is one of the good place to start your search.

One particular battery from Hobby King we know works is the Zippy battery.

The Turingy batteries tend to be a little bit too thick.

I hope this helps.

If you guys test certain batteries and know they work please feel free to add it to the wiki. If you need a wiki account just PM me with your nickname choice and I will make you one.

Cheers Esden

That Battery you linked to is a 2 cell. Just want to double check because the battery linked in the other post was a 3 cell.

Damn, sorry about that.

I mean the 25C 2200mAh 3S zippy: http://www.hobbyking.com/hobbyking/stor ... _25C_.html

Also I looked what we also tested and the 25~50C 2200mAh 3S Turingy nano-tech fits: http://www.hobbyking.com/hobbyking/stor ... _Pack.html

Got my espresso today... Psyched to start on it. Was hopping it wasn't quit that much of a kit for the price point but oh well.... Finally here.
This will probably be the begging of a slew of questions:
1) Great info on the batteries... Takes some of the overwhelm away... Now stuck on what charger. They range from $9 to $200. Of course I will want to pick up half a dozens packs... I don't want to spent a day charging like I do now for my AR Drone. So what multi charger do you recommend and why ?
2) Radio.... Still leaning towards the Spectrum Dx 18. Tad pricey... Anyone settle for the dx8 instead ? Anyone have the dx18 ? Any advice ?
3) saw the number 12 on my kit... Assume I am number 12 of the 18. Thought I saw a piece was missing and was being shipped.

Other then that....post more videos or linked to others who have posted. Checked out the motors, those are cool motors. Aren't those made by y'alls day job company ?

I also have a difficult time picking chargers. I can't tell you which one to get, but here are some suggestions:

Li-Po charging
3 cell series (3S) capable minimum
2.2 amp charge rate for a safe 1 hour charge time
4.4 amp charge rate for a 30 minute charge time, but possibly reduces battery lifespan
Balancing for increased battery lifespan and performance (by how much, i don't know, 10%?)
AC/DC input for use in your home or car
