<p>Yes, the same for me - 2200 mAh 3S gives me 5-7 minutes.</p>

<p>Glad to hear that :)&nbsp;</p><p>I will try 1045 props as well. Thanks for the update!</p><p>What battery do you use and what's you flight time? I have a 2200 mAh battery and it takes about 5-7 mins to discharge it completely.</p>

<p>...and the printed frame is much more durable than I thought. The crash that killed the 8'' propellers was quite horrible and caused absolutely no damage to the quad itself ;-)</p>

<p>I ended up with basically sticking around the standard values - just increased I and D a little bit. As I killed my 8 inch propellers, I tried it with some 10 x 4.5 ones I still had at home, and it works really great. It's much more powerful, quiet and controllable. BTW - I published some of my add-ons here (plywood substitutes, GoPro mount and GPS add-on).</p>

<p>I'm not too successful in tuning either.. I believe that you must finetune PIDs for your quad anyway. Mine also isn't stable enough in the air, i think my remote is not good enough for it and stick in mid position gives some floating.. Since first step is to trim your remote, so it wouldn't drift when hovering. my PIDs are for R/P/Y 8.3/0.015/20.&nbsp;</p><p>Anyway it looks to me that multiwii is not so user friendly and requires skill to tune everything correctly. Keep trying and you will make it!</p>

<p>Finally, it's flying ;-) I don't know if it was the wind we had during the last few days, but it feels like the MultiWii is not yet tuned perfectly when using the factory defaults. Did you tune your PIDs on the MultiWii or are you using the default values? If you changed them, could you give me some hints on your settings? That would make tuning much easier as I would have a starting point.</p><p>Thanks!</p>

<p>Yes, that's what I also found. The landing pads I made are also connected along the longer side of the copter - you can already feel that this adds lots of additional stability.&nbsp;</p>

<p>Good :) Enjoy your drone!</p><p>Though i recommend of using braces for the legs (plywood that i've used or something similar), without this brace, my legs would broke almost on every hard landing, but these braces really makes a big difference.&nbsp;</p>

<p>Print and build is finished, it looks great! I designed a new controller housing with a possibility to mount a GPS antenna and some feet as a replacement for the plywood you used. Will post those parts here after testing - I'm still waiting for the postman to bring my receiver ;-)</p>

<p>OK, thanks for the info. At least you can still print some new parts after a crash ;-)</p><p>Print is currently running, I'll let you know about the results.</p>

<p>Frame is pretty stiff. I designed it be like this. This is my v5 quad. I use 930kV motors and 8045 cheap ebay propelers.&nbsp;</p><p>Frame is stiff, but won't last if you do a heavy crash to the ground. so be careful. That's what i've painfully learned..</p>

<p>Looks great! How does it fly, are the arms stiff enough? Which type of propellers did you use? I assume 7 or 8 inch?</p>
