This is a project for a filming gimbal drone, an V-Tail 600mm. The frame is a mix of scratch builds parts and other racing drones spares. Arms are 12mm booms (maybe too flexible), brackets for Radiolink SE-100 and gimball STotm32 are spare racing quad 4mm arms. Legs are cheap fiberglass rcplane landing gears. The tail are made whit some "rotorbits" parts, scratchbuild alluminium plates and a lot of epoxy glue. To control gimball I use Turnigy TGY-i6S control whit ppm TGY-iA6 receiver so it is some kind of two manned drone.

So what firmware are you running on the FC? Betaflight or iNAV or what? Hows stability and oscillation?

Plasencia   Jun 25, 2018 

Betaflight. Stability and oscillation improved after lost of flights and tuning filtering. V-tail only for aesthetics, rear motors works 1,20% more. The yaw authority are not so important in a filming gimbal drone but is a challenge to tune and you can learn a lot of stuff. Motors are all softmounted and a 1000mF capacitor deals whit noise well. Althougt funny, its a very fragile frame and fear factor makes me not to push the limits of this quad, first version whit aluminium booms was total destroyed after a violent crash

Hi, im working on a smaller v-tail, but am having an issue. can you share the motor ordering and direction? thanks!

Be careful the motors of the rear are upside down, but all the props are up as usual. Motor ordering the same as standard quadcopter in betaflight

whatever happened with this thing? i'm working on my prototype. i'm going with 400kv quanum mt 4012 + feichao cf 1555 heavy lift props in the front, and quanum 4108 + 1155 feichao cf in the rear at 580kv on a mostly stock reptile mosquito 400 that i've extended with tarot anti-vibration mounts, while the rear has the same mounts, 250mm x 16mm tubes that are bolted to the single rear tube with a set of 120deg landing gear adapters.. the idea is the front will do the heavy lifting and the rear will only have to lift about half of the battery weight, and be able to whip the craft around on a pinhead. the payload will be quite extensive. the machine will be ran from a rasp. pi zero + 4g cell modem + pixhawk. i'm hoping to be able to lift up to 20 lbs full payload... which may be asking a lot. this thing should be quite capable and and needs to be fast enough to catch and engage choppers that come within range of the base, so to speak.

I love it! Looks like a creature from the Lost World

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..
