E.T.s Flywoo Mr Croc 5 inch Quad Build...Long Range?
« on: September 27, 2019, 04:02:40 PM »

 Not posted anything for a while, but decided to build this one after the success of my UHF Stingy 5 inch long range quad build.
 Chose this one because of the Dead Cat layout possible and no props in shot set-up. It also has real estate to cope with no less than 3 standard or 20mm FC based pcbs. The front bay is vacant right now while I consider purchase of a Split type FPV Camera.
  Some parts recycled from my Martian 2 which had been flown to death.
 I have recently been flying a moto glider on my R9M system and it worked fine with a 1280mhz vtx alongside. Not sure if this Quad will be okay though..hoping it will be with the horizontal polarised R9 versus the vertical polarised vtx.
 If it doesn't, then I recently bagged a bargain at HK, an 8 channel EZUHF Diversity receiver for.....15..!!!..result.

 Basic Specs:

 4 in one Racerstar ESC (cheapo)
 Matek PDB (to provide 5v for the FC and 12v for the VTX)
 R9MM receiver running Flex on 868mhz @ 500mw
 Matek F722 Flight Controller (not cheap)
 200mw 1280mhz vtx with standard RD.
 Camera to be decided but a cheapo FXT micro for testing.
 Betian 220 GPS.
 2200mah 4S Lipo.
 Custom made hex spacers (because Flywoo decided I didn't need any)
 


                                                                                                :vulture:

Looks like a big quad with lots of space. Great to see a new build. Hope the maiden goes well.

Have you gone with lower kv motors to get more endurance?

 Hi Dave,
              No, they are just cheapo Racestar BR220 2300kvs I think...I can usually get around 7 kms endurance on a 2200mah 4S giving a flight time of round 12 minutes consistently....
  I deliberately avoided the expense of a 6 or 7 Inch Quad...If I fly out 2 kms with this I will consider myself pretty brave TBH.

 Hi Ian,

             Yes, it's a nice Frame with 3 different arm configurations. Apart from the 3 Bays, the other reason I chose it is because it lends itself to an underslung Lipo. This leaves the whole top deck clear for an HD Camera or whatever you want.

  It's a pity more Frames aint like this one, instead of all cramped up for space.... A bit pricey though...

Yeah this is what I don't now like about my Armattan Rooster build, everything is just too cramped inside.

Nice build.

 Cheers Jake...Its pretty much finished now. Its been test hovered and now the Camera and Video system is in place. Some minor work on the Lipo seating pad and its done.

Okay...Update time, nearly finished..

 Test hovering went well, no real issues. Since then the Video and Camera system have been fitted and about to be tested. Some more photos showing some of the parts used....
    I went cheap and fitted the new Caddex Ratel, this being the latest version with the screw on rear cover and curved 2.1mm lense reducing fish-eye. Set up and tweaked as per the Pirates suggestions which took the edge off the noise very nicely. The micro LC filters are fitted close to the device in the power feed lines to reduce noise. These little filters are perfect for quads or anything really and have proven very effective. The Matek PDB provides a regulated 12v supply for the 1.2G vtx, but predictably, its a dirty supply, hence the filters.


 












 Conclusions:
                    A very nice Frame with lots of space for multiple PCBs. Three Arm configurations available, choose the one you want. I like the Dead-cat layout for no props in view and the slightly stretched X which I find a little smoother in flight. A completely clear upper deck and an under-slung Lipo. The 1.2G video has proven to be utterly solid as usual, although I have yet to see how the R9MM will handle it on a Quad. This combination works fine on a fixed wing.
  Both Video receivers in my much loved 5.8G Viper Goggles have failed a while ago, but they still work fine close range with my 1.2G GS and relay, no problem. The optimum Lipo appears to be a 2200 mah 4S which gives around 7 kms range on previous similar builds, but this quad will carry a 3000 mah as well, not sure if it will extend the range though.
  If it proves to work okay, a Betian 220 GPS will go on the upper deck up near the Camera..

  A short hover test to prove the video and camera set-up....Its just a crude snapshot, but very pleased with this cameras WDR and colour rendition.
  Video is nice and clean with no ESC noise evident, looking forward to a proper flight test.
 The Ratel is available from Bangoods EU Warehouse right now, about 25 and a two day delivery time....

Did I finally convert you over to the idea of a CMOS sensor ?

 Hi Wayne,
                  With the Ratel, it would appear so, although it may need the ND filter in strong sunlight...The idea is to use it over Spring when its overcast here most days...So far though, it looks very promising and the tweaks suggested by the Pirate definitely had the desired effect for me...My Runcam Sparrow (the big one) is absolute rubbish in comparison, and that is also a CMOS if Im not mistaken..? Thats the camera that likes to make the sky have random blue blobs in it, shocking.
