Hi Guys, Been off air working on other things. Just thought I'd get back to you all and let you know I managed to sort out the problem with my T680. I lowered all the gains and put a 4S battery on it and it works a treat, no more flips etc in fact I've managed to fly it with my Attitude Gains...

Thanks Corey, I recognise much of what you say and have thought about trying to fly out of trouble but my immediate reaction which is instinctive is to try and calm the aircraft and stabilise it back into a hover. I have ended up by trying to descend even from that low height because I...

Thanks Corey, I follow that logic and that will be my next thing to try out...again. But with trepidation, this was what happened at 100% across the board http://youtu.be/SdONrnICMGg there are other videos with a similar story as I slowly increased the gains. It is interesting to not that some...

Well after several days of not being able to fly because of the weather there was a break this morning so went for a test flight. I have checked absolutely everything suggested in this thread. I have lowered the CoG by moving the power board to sit under the rails below the bottom plate; put...

Hi Ken, I considered this but the problem with the 680 plates is the size of the holes in the top and bottom plates. They are just a bit too small to have the Naza sitting just proud as the leads from the ESCs, RX and especially the LED and PMU all snag. I actually removed the small spacers...

I know the auto take off is not everybody's favourite function but I have got used to it. just give it the beans to 'pop' it off the ground and then let her settle down at about 4 - 6 feet. On the continuing saga of my problems I now think it may be a dodgy ESC, take a look at this video...

Hi Guys, All ESCs have been calibrated, repairs effected with parts that I have (shorter hex spacers etc should arrive in the next couple of days), will probably take a leaf out of Kenn's book and buy some wooden dowels rather than aluminium to feed into and join my broken skids together as I...

Yeah going to give it a go one by one as I don't have a harness. I have a separate power distribution board as the version of the 680 I bought does not have the integrated one so should be no issues there...

Hi, I'll give that a go once all repairs complete. Surely balanced props are just fine tuning to eliminate vibration to ensure a steady picture for AP? I accept that if your props are ridiculously unbalanced or badly damaged that could introduce unwanted flight characteristics. The same for...

Morning guys. The alarm sounds like the low voltage alarm that I fitted to the battery, you see it hanging down in the link below and hear it too. But the battery was fully charged and still reading 78% when I checked it after the crash, it reads 82% at the moment. The battery is usually used...

Over compensation is what I think too and had hoped that the adjusted gains from the previous day would work. They did make a difference on the previous flight (not shown), I had a very stable 6 min flight on a 3S. All connections good and certainly seemed to climb and fly out and back ok...

Hi Motopreserve, Many thanks for your input I certainly didn't know about the pancake motor issue but are 750kv motors pancake? I always assumed that the pancake motors are the larger flatter ones typically used for gimbals? I realise the 600khz thing is a bit of a marketing ploy since the...

Hi Corey, I wasn't yawing and I thought the SimonK flashed ESCs were the Bees Knees, certainly all the blurb on the internet suggests that they are fast. 600khz which is an improvement on the 400khz ones I use on the Cinestar. I didn't calibrate the ESCs as the instructions that came with...

Hi Guys thanks for your replies much appreciated. The first flight today was on a 3S, flew for 6 mins without a problem. Thought with less power that it would be easier to set up but obviously less endurance/flight time. When all ok I switched to the 4S, the video shows the 4S flight. From...

Hi, came across your thread and I seem to be having similar issues with a self build Hex. Had four really difficult flights yesterday resulting in a minor crash and damage to one of the skids. All gains were at 100%, I had planned to gradually increase them rather than go too high and...
