Thanks Scotth. I spent time talking with a lawyer regarding this on Friday afternoon, you're right, you can apply for the 333 without a pilots license but will need to hold a Sport Pilot, Recreational Pilot or Private Pilots certificate to fly for commercial reasons. At least that's the way...

Regarding the 333 exemption, I can't determine if I can apply for the 333 with a sport pilot license as opposed to a private pilot ticket. Has anyone applied with a sport pilot license? Thanks, Dave

Some of the DJI problems can be traced to poor bullet connector soldering. My F550 flew fine for the first 20 or 30 flights, then it started getting more and more erratic, then crashing on a regular basis. My problems were solved when I re-soldered all the bullet connectors, in fact I soldered...

What is the asking price?

That is very cool! Just how did you do that?

Thanks VIQuad. I can't tell from the photo what that is, is it a filter? Could you re send the photo just a little larger? Thanks.

Has anyone used a Polar Pro polarizing filter while using a GoPro on a Stella gimbal? Just wondering if the extra weight will cause the gimbal to not work properly?

Good luck, bensid54, my guess is that your machine will fly properly. Let me know if it works. Best, Dave

Has anyone used the new, E 300, DJI motors, props and ESCs for the Flamewheel 550? If so, what improvements have you noticed? Thanks! Dave

bensid54, The handling of the F550 was the same with the Naza and the Naza 2 before soldering the bullet connectors. What I did notice was that the F550 became, increasingly, more erratic over the time I used to try adjusting gains and swapping out ESCs and motors. My guess is this was due to...

I also struggled with this problem, instead of listening to the experts I swapped out my NAZA to a NAZA 2. No luck. Then I striped the plastic off of all the bullet connectors and found not only were some loose, at least half of the 18 connectors had some kind of oxidation on the motor side...

Is this Bart's site? http://www.mikrokopter.us/

Multirotorxy8, thanks! Do you have a link to Bart's site?

Thanks Emowillcox, this is my first scratch build and I'm just trying to eliminate numerous rebuilds. How large is your quad?

Hello all, Are there any guidelines for building a quad/X8? Specifically boom angles and whether or not the motors must be placed in a perfectly symmetrical manner. Or will a good flight controller compensate for a non-symmetrical design? Right now (if I stick with the tentative design)...

Thanks Pete!

Hi All, I'm looking for a DC to DC converter that takes voltage from an 11.1 volt 1300 MAh 3S LiPo down to 3.7 voltage that will run a GoPro Hero 3. Can anyone offer some suggestions for one of these? Thanks! In total, the battery runs the Tarot, GoPro Hero 3 and a 1.3 Ghz video down-link...

I went through and checked all the bullet connectors, one on the right side was out about 3/16 inch. Two on the left were out about the same distance. I flew for 8 minutes on a 5300 mah battery and all was well..... until the second flight, about 4 minutes into the flight, glitch to the right...

Thanks hjls3, I'll check all of the connectors.

When flying my F550, Naza, GPS in Atti mode it will hickup, that is, it will drop to the right for just a split second then recover. This has been occurring every flight for the last 20 or so flights and I've made sure it's not a finger twitch. The motors are warm, not hot. Battery warm, not...
