Garden racer
Since I moved to HD I havn't really had a good garden racer. I thought I'd use my analog 2.5" for quick sends around the garden, but no - with the taste of HD the analog quads stayed grounded.
My 3 inch 4S is just a bit too quick and heavy for garden flying, so I had to build something smaller and lighter.

After looking at all possible frames I finally decided to go for the iFlight Titan DC2. It would take 2.5" props, had plenty of space and additional ducts for flying indoors (but the ducts didn't last more than one flight) ...

Custom parts
Since I wanted to use custom parts I had to design and print different mounts.
The flight controller / AIO is a standard whoop size FC but the frame uses 20x20 or 30x30. Easily solved with some spacers.
I didn't want to mount the Vista in the FC stack since it would add gyro noise. Instead it's screwed into fixings in the top plate.

Flying
Yes this thing flies! It's a bit heavy compared to my analog 2.5" but this performs great. If I'd change anything I'd choose higher KV motors. It's a bit slow on the punch, but that's compared to my hysterical 3" and a 5".
I get around 4 to 5 minutes of somewhat aggressive flying on a 3S 450mAh which is quite good in my opinion.

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..
