I put tape over all the vents on the quad and it seems to help. I never had anything go wrong while flying so I can't say how much the tape helps. The worse part for me has been my Nexus 7(newer version) doesn't last long as for responding to any touch commands after about 10 minutes when flying at 18f degrees. I bought one of those setups that msinger gave links to, but it arrived after I crashed my quad so I haven't been able try it out yet. It is made really nice. It does cost a little too much in my opinion but if it works as well as it is made then I shouldn't be that put out over the price.
Scampaboy, your video had me nervous throughout the length of the video. For those being your 1st & 2nd flights you did great. But I kept feeling like I was hearing the power hesitate in 2 or 3 parts of the video. That there had me most concerned. And then it sounded like your props were either not installed correctly, or a couple of them were bent a little. You can hear that sound when you climb in altitude fast. The quad reacts with a odd sound that is not smooth. I was also expecting to see the quad drop a couple of times you were descending from higher altitudes. It almost appeared as though it was going to go into a vortex state and then drop. Other then the tip over you did good. Make sure you do calibrate the compass properly. They may have been why you had the tip over that you did. Oh, and no doubt get your some floaties on the landing gear when the lake begins to thaw.
