Dirt Cheap F450 iNav test platform

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.

Looking great! Exactly what I'm planning to build. What kind of weight does it lift?

cjdavies   Oct 04, 2018 

The power train is essentially the same as a Phantom, so a small action camera + gimbal is the realistic sort of weight you'd want to lift.

Awesome! That really makes me miss my F450. How well does it hold position?

cjdavies   Jul 21, 2018 

Maiden'd today in 20mph wind & position hold seemed fairly decent but altitude hold was iffy - not sure if it was the barometer, the tune or the hover throttle/deadzone/etc. settings. Just happy it flew, as the last thing I flew (Pixhawk 680) made it 6ft before faceplanting the ground :3

You got foam on the baro? Wind affects it a lot if it isn't covered in foam/

Yup, baro is on the bottom of the FC & there's a piece of foam sandwiched inbetween it & the frame. I'm going to wait until I get the chance to fly on a calm day before I make any further judgements.

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.

Mine is a cheap Diatone clone of the F450 & has 30x30 mounting holes.

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

Update! Happymodel has released a new V2 Frame which uses a more durable plastic. The Happymodel Mobula7 is one of those rare treats to hit the micro scene. Countless models hit the market every month, but this one just happens to check all the boxes. It's a 2S brushless micro with a 75mm motor stance. It's slightly larger than the more traditional 65mm brushed micros, but it's still quite small...
