Re: Flight Modes and FPV

I used to FPV in horizon mode but have recently switched to acro.
Good tuning is key to any flight mode though

All the flying in this video was done in horizon mode.


And this all in acro mode.

Re: Disarm motors on crash...

I heard one guy used a glass fuse on the main battery line placed in such a way that in a crash it would break, cutting all power.

But I find disarming a natural reaction now, if the copter is going down I know I just have to pull the sticks a certain way and everything is safe.

you can add a layer of thin double sided tape to the boom before clamping the motor mounts on. It wont stop them rotating in a really big hit but it'll help with normal use.

Re: Help with a project: Strip multiwii back to ppm in-servo

The sliders being on the wrong channels is an easy fix.
When you uncomment the define for ppm in just swap around the order of the channels.
As for the second bit, you did read start then read??

I to had a look at that very board but wanted to keep everything in 1 IC if at all possible.
I see it uses serial as well, although it runs up to 38400 (same as my gps) would the extra traffic cause things to jam up and slow down?
