Great flying by the way, this is what I want to do with mine.. just too apprehensive about it still. What are you using for your FPV rig?

spag
GWS props work great for FPV, but suck for trying to get nice smooth video. especially if you are moving forward in a fast direction. they flex to much. if i use APC props the problem goes away every time. i just like GWS becasue they are cheap and i can try going thru tight areas without destroying 8 bucks in props like i would if i used APC. i went thru a few props that day Flying thru that barn and under the bridge. i;m using a 200mw 900Mhz video TX with Ibcrazy's V antenna. 2 recievers with 8 DBI patch antenna's and Eagle Tree for diversity. Fat Shark Goggles, 17hz saw filter on the RX as well.

vee Antenna

Hey i have a probably simple question. I also have a 900mhz vtx and was looking to start upgrading it a bit. I want to get the ibcrazy vee antenana, but when i look on their website, there is a "inverted Vee antenna" available for 900mhz and also another one called just "Vee Antenna" available at 910mhz.... so im a bit confused on which one is appropriate or what the difference is? Sorry for my ignorance, im a bit new to the fpv stuff and its becoming addicting very quickly!

Thanks!
Marko

is there any tilt compensation in the code? did you calibrate the magnetometer?

i would go with the Vee Antenna at 910mhz. you can make your own very easily. just search RCG for IBcrazy vee antenna.... yeah this sport is crazy addicting.

Nice thing about the Seeeduino Mega is that you use the "power in" plug that takes between anything between 6-20 volts and uses the built in regulator to power the board, so you take power direct from the battery, not the ESC.

Honestly with all the advantages of the Mega its hard to understand why its not the primarily developed platform as the only down side is it costs $43 and is slightly bigger than the pro mini.

I'd say that most folks building MultiWii copters here are at least somewhat frugal but still spend lots on their projects so the extra $23 is not really a big deal is it?

And the size is only going to make a difference for those building the tiny little quads and tris that we don't see that many off anyway.

but I digress a tad,

I really did not "gram watch" on my first Wii build, but I will on my FPV rig. I just wanted to get in the air and see if I liked it. I was blown away at how well my wm+ only on the warthox shield worked. Now, that I know what to expect I can experiment.

I have dozens of flights with all four ESC's fully connected to the shield and let it power the Rx via the connections for roll, pitch, etc... Never had any issues or glitches.
