There are no burnt traces and I don't know if the recoms are working or not, I haven't connected battery power to the board since the incident, I've only applied 5 volts to the other side of the recom circuits through a USB connection. There is no sign of anything burnt anywhere on the board...

Yes, the recom is the voltage regulator that takes battery input voltage and drops it to 5 volts. They're the large rectangular components on the underside of the board, the one next to the capacitor is for the controller circuitry and the one on the opposite side of the board from the gyros is...

I replaced only the recom for the servo power, I knew the recom for the controller circuits has to remain at 5 volts. I did find the F/C board schematic that is publically available and it's not as detailed as any of the ones I used long ago when I did board repair for a living (we also didn't...

OK then, I'll save you the effort. If you want I'll send you a set of 10 x 5 Graupners from my stock of spares as long as you replace them once they're back in stock. I'm waiting on the 11 x 5 to try out on the Droidworx Hexa which will take up to 12 inch props, I have a set of APC 11 x 4.7 that...

First off, which props? Some I would cut, others not... If you have room to swing the 11 inch props, just use them as is, the stock motors should be able to handle them. I'll be installing a set of 11 inch on the Hexa as soon as the sled dogs from Fedex make it across the snowbound city from...

Sure did, I wouldn't have bothered to change the recom if the servos weren't 6 volt digitals. Anyway, to get back in the air in a reasonable amount of time I just ordered a replacement F/C from Adam, I'll deal with the bad one at some point down the road. If I could find a full schematic for it...

So the verdict is in, DO NOT change the servo recom to a 6 volt unit to supply more power to camera mount servos. It appears that there is potential for the 6 volts to get back to the control circuitry side of things and there are components there that do not like more than 5 volts apparently, I...

Yeah, but unfortunately it may not show up under low voltage, low current conditions, and if it's a noncritical circuit like the servo ports it may not show up on diagnostics at all. I will try connecting the F/C to the laptop and see what I get and go from there, but I'm very much afraid this...

Yes, the MK, and now I have the worst possible scenario, visible smoke on power up, distinct aroma of burnt electronics, and on close inspection no visible sign of anything burnt on any of the boards, nothing, nada, zilch...:confused: :( There's no way I would dare put this thing in the air...

It was bound to happen sooner or later and I'm glad it happened where and when it did. I was going to do a test flight over the house to check out the most recent changes to the camera mount settings on the Hexa and when I plugged the battery in I saw a little puff of magic smoke inside the...

It can though if you have all standard MK electronics assembled in the stack in the proper order there shouldn't be any problem. I have the XBee TX/RX setup velcro'd to the side of the dome cover, an I2C isolation board directly underneath the GPS board, and a receiver diversity board hanging...

Now that I've rebuilt the Hoverfly into a frame capable of carrying camera gear and the firmware is allegedly stable enough to keep it from flipping in flight, I decided that it needs better motors. Part of that decision came about while watching the props spinning at low rpm and finding that...

Which means the 11 inch probably are as well, now I'm glad I ordered the APC's and stocked up on the 10 x 5 when they were still in stock. Ken

There needs to be some amount of play to allow for heat expansion, otherwise the motors can bind up in hot weather. That said, most motors have a set screw that holds the can to the shaft, loosen the screw and it may be possible to remove some of the excess play by moving the can down lower on...

APC props are a viable interim solution, I'd use them over EPP or cheap Chinese props anyday. I have a set of APC 11 x 4.7 on the way while I'm waiting for Graupner 11 x 5 left hand rotation props to be back in stock. Ken P.S. due to Chinese New Year there won't be much of anything...

The lower of the two weighs 115 grams or roughly 4 ounces, the taller one slightly more. Paint won't block the GPS but you might be surprised at how much weight it can add. Ken

I use an eFlite 3S 800 mAh mainly because I had a pair of them leftover from when I had a Blade CP heli. Can't say how long a 360 would last, I've never had one that size, the 800 lasts through 3 10 minute flights no problem with plenty of power left. Ken

No you don't want to restrict reception at all, doesn't take too much for the GPS to lose the signal entirely, the covers are there just to protect the electronics from the elements. Sometimes I wonder how much effect just using the acrylic dome has on signal strength, but it seems to work...

I'll let you know once I get it fully dialed in, it's going to need some tweaking now with 6 volts going to the servos. I was also told by Rob from Droidworx that Kim at Photohigher is spec'ing new servos for the mount that are better than the upgraded ones my mount came with and they will be...

The short answer is no, the longer answer is you want to have some sort of covering over the electronics for protection. The level of protection depends on how much you're willing to risk the board(s) being damaged in a crash or anything other than an upright landing. I use 1/8 inch thick...
