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

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..

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

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.
