"This analogy sums it up pretty nicely. I bought a phantom 4 after about 4 years of building apm and pixhawk-based craft. My main pixhawk craft hasn't left the shelf since I got the P4. The HD video range of lightbridge is truly impressive. Th…"
"I switched from 123D to Designspark mechanical (also free) a while ago. It has a few more features with managing components and versions, and seems a little better suited to 'engineering' type of projects than 123D.

"Well done Eliot. I know there's a lot more undocumented use going on in construction than people are willing to talk about publicly. Construction folks are generally very risk and liability adverse when it comes to things like this.

"Tim - This log shows entering loiter mode only twice, the first time for about one second, and the second time for about 4.6 seconds. It might be slightly more helpful if you can enable RCIN logging by changing your LOG_BITMASK value from 864 to 89…"
"Alex - sorry if I missed this earlier in the thread, but are you using the latest version of MP? There was an issue that came up around -rc4 with the version of MP out at that time that was reporting 'false' EKF errors. As far as I know, everyone wh…"
"Well, three props were off the craft after the crash. Two had broken posts on the prop adapter, and one was just removed from an intact post, spinner nut and prop on the ground nearby and undamaged. Prop adapter post was not bent. I had assumed…"
"Thanks guys; I think the most likely explanation at this point is a loose spinner nut, not software.
One of the props that was off after the crash had an intact adapter, spinner nut also intact but detached. I initially attributed this to the motor…"
