My name is Mike.

This is my fourth quad copter build and I'm looking for help with and issue with what I believe is a battery issue.
I'm building a Tarot Iron Man 650, below are the components used.
4 - 340 kv motors
4-15" props
4- 60 amp BEC
Naza M controller
Devo 7 remote & receiver
5S 5000 25c 18.5v lipo battery

I currently had a 3S 25c 5000 lipo with everything above except for a different frame which was a DJI 450 frame and everything worked fine.
I calibrated the battery with the Naza utility application but when I tried to re-calibrate the ESC all I get is beeping and no lights on the esc calibration card.
this issue is the same for my quad that has been flying perfect and the new iron man with just a larger battery.
Is the battery defective?
Any help would be much appreciated!

Just posted a new review of the UDI U818A quadcopter - its a solid value for any beginners looking for their first video enabled quadcopter to learn to fly on. Read the full UDI U818A review here with pictures: UDI U818 Review on QuadcopterHQ.com


The UDI U818A comes in a medium sized cardboard box with a handle for easy carrying on top. It comes with all the quadcopter accessories that you need to start flying, including:
  • UDI U818A Quadcopter
  • One 3.7V 500mAh Lithium Polymer Battery
  • 2.4Ghz Remote Controller
  • USB Charging Cable
  • Instruction Manual
  • Spare PropellersUDI U818A Packaging

UDI U818A Quadcopter Design

The UDI U818A is similar to many other quadcopters in design, with a plastic cross frame and pretty much entirely plastic parts. It is a mid-size quadcopter, measuring about 13″ by 13″ and about 2.5″ tall. If you’re familiar with the Syma X1 quadcopter, it is nearly identical in size – and has very similar propellers too! Personally, I think this is a great size quadcopter to learn on as it is big enough to see easily, it can be controlled with easy and isn’t too twitchy like some micro/nano quads, and its still small enough to fly indoors.

The motors are standard and the drive assembly is exposed just like in the Syma X1, so you can see the gears that drive the propellers. Be sure to check them for hair, dust, etc. after a few flights as that can interfere with your...Continue Reading

So I have been playing too much Ps4....i bought my nephew Proto x. I got to fly it and I wanted something smaller than my Nano QX.

I was going to buy one on Monday but they were out. Ended up leaving the LHS with a Kodo Dromida...great flyer

I went back to give my review on the Kodo and pickup my Proto but they were still out.

The LHS owner hands me the Faze....I didn't want to pay more but hey it's Horizon...

I am glad I got the Faze instead of the Proto X....this guy has more LEDs and flies so much better. I can not believe how much I like this little thing after 2 flights.

hello guyz!
help me out here i tried everything i know and checked every yb video on the net and could find the reasons why my tarot 650 quadcopter with kk2.1 board wouldnt fly and tilts at one side at a the takeoff throttel level ...

i used the standard gains for kk2 and even lowered them down more and still ,the rx sensor on the board is reading correctly and telling me that my tx is good "initially all 0" ...

-rctimer 5010 360kv motors
-carbon fiber 17.5 x 5.5 props
-kk2.1 controller
-30A x4 Quatro sky lll esc's from favourate
-tarot fyi 650 fram with motor mounts
-simple tx rx hobbyking 6ch radio "thinking its the reason as the to ARM the controller i have to move the th stick to the left up angle rather then down right angle" (waiting for my 9ch turnigy thats taking forever to get here from china)
-10000mah multistar battery 4s

i uploaded the videos for you to see my problem

Here's some wacko fun at the Melbourne Air Show, guys!

Kent Pietsch is up to his old tricks (and a few new ones) in his Jelly Belly Stunt Plane, a 1942 Interstate Cadet, as ex-con 'Chuck Dramamene' who built the plane in prison and smuggled it out one piece at a time.
