Cheerson "Phoenix" F330
By fradioflyer on Jul 22, 2015
Rising from the proverbial ashes of a crashed CX-20, I transferred the internal components over to a DJI F330 frame kit. Before the crash, I had replaced the FC with a full APM kit much like the one linked here. If you want to replicate this build, there's no reason to buy and crash the CX-20 first... just buy some motors and 18-amp ESCs. ;-)

I cleaned up the wiring of my FPV monitor, eliminating the clunky power plugs and RCA Connections. Once I removed the back cover of the monitor it was pretty simple... Red to red, yellow to yellow, etc.
I probably could do the same with the vrx and eliminate those plugs, too...
That is TRULY a cram! Good job!!!
Were did you get that battery strap?
How did you mount the FPV cam?
Hey I've got that Gforce as well. How does the Blackmagic compare? I'm not all that happy with the Gforce as it seems to have lost some of its capacity over time.
I like the BlackMagic. Depending on how aggressive I'm flying, I can get up to 1:30 more time from it compared to the GForce. These batteries spend a lot of time at just a storage charge since I'm only flying this model once or twice a month, since early May, so I can't guage whether they've lost capacity.
I don't know why that LCD monitor link resolves to $75.91. It's only $24.98.
Just came in here to see the updated price and I notice the item is not on my list any longer... the CX-20 is not there, the LCD monitor is gone, too. ??
Edit: I re-added the missing parts. But I'll say I also "lost" an Amazon part on my other build (I fixed that, too) but I wondered if there was some consequence to you fixing the Amazon prices.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

I took advantage of the unseasonably warm weather this weekend and rediscovered how much fun it is to fly this little quad. I possibly could have flown more, but something peculiar is going on with the battery charger. So, with a 4s 10ah battery, I can set the charger to 10amps and an empty battery charges full in under an hour. For these smaller batteries, I dial it down to 2.7amps and they charge really slow...more than 2 hours!
I'd take a spent battery at, say, 10.8v, plug it in for a balance charge and the voltage would jump to 12.8
I can't explain why.
Hmm, I wonder if the battery is still good? Do you have another to try? And yes, I'm more and more inclined toward smaller quads simply for the fun factor. It's a real burden to lug a huge rig around.
I have two 2700 and one 3000mah battery for this quad. All 3 charged the same way. I drained them all to their ~80%, plugged each into the charger afterwards and I guess it's the charger, opted to put out 12.8v and very low amps...and they all took forever. The 3000mah took 3hours, 37 minutes!
Must be a setting thing then. Maybe there's a thread about the charger on RCGroups?
I found the Turnigy Reaktor thread on RCGroups and learned that the 12.8 volt output was a "feature" of the charger...compensating for voltage loss of the charge cable. And that got me to wonder if there were other compensations with the amp load as well...
Since I sold my iMax B6 charger along with all it's charge adapters, I had to buy another one with an XT60 connector. I hadn't used it before this weekend. I was suspicious of new cable to begin with because it was wired with 18-gauge. I just re-wired it with 14-gauge so I'll test that later today if I can make the time to fully discharge a battery.
How would the wire gauge affect the charge time though?
Long charge time is a factor of the low amps it was pushing. It was charging at ~ 0.3 amps... like 1/10th C?
Anyway, even while there could have been any number of reasons in play, the new 14-gauge charge lead is charging a depleted battery at 2.7A, like I expected all along.
There you go, should be getting 45 min charge times now?
