Orange Fury - 4" Armattan Japalura

The 4" Armattan Japalura is currently my favorite quad so I have a few of them now, this is actually my 3rd one. I again sent some braces to "Pig" on RCGroups and he did a wonderful job stripping them and anodizing them orange. I used an orange paint pen to highlight the edges of the frame and then an Xacto knife to clean any paint that was on the top or bottom of the frame.

The 4-in-1 ESCs are becoming very popular but I personally would rather have separate ESCs in case one of them needs replacing. I'm using the Armattan 20a ESCs because they are fairly small/light and are running D-Shot 600.

The flight controller is a BetaFlight F3, some people don't like it because the ESC power pads are on the bottom of the board but I actually like it that way since it makes for a cleaner looking build.

The rest of the electronics consist of RotorGeeks 1407-4000kv motors with HQ 4x4.3x3 V1S props and RMRC orange prop nuts, an Eachine VTX03, LemonRX DSMX satellite and a Foxeer HS1177 camera with the 2.5mm lens.

The weight without a battery is 182.7 grams.

Love your build, where did you get the orange metal from?

Thank you very much. I sent them to Pig on RCGroups, he stripped them and them anodized them for me. He did the same thing for me with my Blue Japalura build and Tiger Chameleon build. You can contact him through RCGroups here. https://www.rcgroups.com/forums/private.php?do=newpm&u=115621

Question I'm looking to do a 4" build using this frame as well. Could I use the emax 2306 2750kv motors or should I simply stick to 3000kv+? Love the build just looking for advice before I start to buy up parts.

This frame is intended for 1407 motors, larger motors won't fit. I've tried 1407 3200kv, 3600kv and 4000kv motors and the 4000kv motors are the best when using the HQ 4x4.3x3V1S props. It literally feels weightless when flying it because of the amount of power/speed it has.

What sized battery are you using typically? I've been using 1350 on a 4" DMR that's sporting Cobra motors running at 2600kv. Just wondering if I can get away with even a 860 4S. Thanks for your input, it's nice to know before I start this build.

A 850mAh 4s is the recommended battery size but I always go one size bigger so I'm using 1000mAh 4s packs. A 1300mAh packs works but it feels a bit heavy to me.

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..
