DarkSonic - Talon v2

Have been looking to do a new build for myself, but too many frames looked the same or didn't interest me.
When I saw UAVFutures post a video of this frame, I immediately bought one from DefianceRC and decided to fill in the rest after getting my hands on it. Finding an F7 20x20 stack proved to be a bit difficult to source, but looking forward to the challenge and 6s rippage!

Build Update -- Passed Hover Test! I really can't get over the look of this thing. Such a beauty.
I'm finding the frame to be a bear to work with at times, however. 20x20 really makes threading a battery strap a chore with motor wires overtop of where the slots are for it. Pod mounting could be improved as the standoff only barely stays in place horizontally by friction when going to screw it in. I may carve a bit of the front and back out to allow space for zip ties that are securing the antenna and pigtail.
I'm also not impressed with the solder pads on the Flywoo FC and the mounting holes shouldn't actually be allowed for M3 as some components are too close to the holes, but it's truly insane how many features they've managed to pack into this tiny thing.

Overall though it was a fun build as every component needs to be carefully thought out and how they will be placed. No buzzer now but I may try to find space for one in the future.

Initial weigh-in 340g dry / 576g with CNHL Black 1300mAh 6S

Future plans after first packs are to soft mount the motors and potentialy find a better way to soft mount the stack than the rubber grommet system I'm using now.

Flight Test -- Man this thing is fast! Not sure if it's 6s, or the frame, but this rig seems to just slice through the air and track amazingly stable. Lots of fun doing fast freestyle and darting through trees. Minor bit of propwash/tuning needed, but already 9/10 on stock PIDs and recommended 4.2 features for "Race/Fast Freestyle."

Looks SIIIICK. Build is clean.
Why the soft mounting? Jitters, or just propwash?
Any chance your rx antenna is slappidy-slappin the frame, causin a ruckus?

Thanks! I always prefer to soft mount and get as much of inherent vibrations out that way before they reach the gyro. UAV Tech always recommends physical before more filtering so thats my MO as well.

Haven't seen any slappity-slaps yet, backyard isn't big enough for punch outs. Hopefully don't have to worry about it too much!

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
