I wanted to play around with an iNav quad but didn't feel like spending much money, so a combination of obsolete spare parts & the cheapest new parts from banggood resulted in this beauty. Special mentions go to the ESCs with their linear 5V BECs & the separate Sparkfun magnetometer because I didn't check realise the GPS I ordered didn't have one.

Wondering if you're still flying this thing and if so, would you mind sharing your PIDs. I just put together a very similar platform to mess with inav and it has some terrible low frequency oscillations. Thinking I need to lower the "I" values quite a bit from the defaults.
I've not flown it since I first built it, it didn't fly particularly well on any of the iNav presets & I never got around to tuning manually. I'm planning to put Arducopter on it (which is supported on some miniquad style F4 FCs like the Matek F405-STD since Copter 3.6) to see if it flies better, especially after an AutoTune, or whether the frame is just too flexible :3
Looking great! Exactly what I'm planning to build. What kind of weight does it lift?
Awesome! That really makes me miss my F450. How well does it hold position?
so I have a f450 with an old DJA naza FC that i want to swap out for an f4 fc and run inav. I was wonndering how did you manage to mount the FC to the f450 plate. The existing slots dont seems to line up with a stanard 36x36 FC.
Hey, I like your test platform build! I'm looking to test a new Pixhawk too. You've inspired a very similar build, I found a necessary upgrade in reliability for Motors, ECS, and props for just about $45 for anyone else who's got a few more dollars to play with: http://store-en.tmotor.com/goods.php?id=726

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..

I'm thinking about a frame like this as my first ever quad - is that a good idea ?.Or what alternatives would you recommend ?
I've only ever flown a model glider (badly) a very long time ago.
Well what is your goal for your first quad? This sort of frame is a good budget option if you want something docile that you plan to fly semi-autonomously with GPS etc. (a bit like a DJI). However it's a poor option if you want something more aerobatic or if you want to fly FPV etc.
