Thanks Bart...its ok Im very informed with wing shapes, lift, drag, thrust & weight factors ;) but your explanation is good...horses for course I think ;) I am using APC 12x6E props for now, but I was going to try 14x4.7 props....its just the hassle of reaming out the centres & ballancing them...

Hi Dieter, welcome to MR forums & may I say what superb filming, very smooth & professional. May I ask what MR you were using in these clips? Regards Ross

Glad they paid for themselves for you Dave, so there is a real benefit to having one. How far do you normally run your cells down to Dave if you are starting to land at 3.5V? Ross

Bart, so a larger diameter prop with a smaller pitch will make these MR's quite floaty? Ross

I thought 4s would kill the strip LED's but if you're running yours like that, I'll wire a strip of 6 & give it a go. At the risk of sounding completely lame...the ACC calibration is top left on the throttle stick, do you then write it to eeprom on the top right or straight from ACC to motor...

It is indeed Jim, with help from people like yourself. Now I want to get out & fly...if the 10-15MPH wind yesterday that I flew in was anything to go by, then I want to go out NOW ;) Ross

Havent got navi or gps, not yet anyway. I'm hoping to get an OSD so that my camera operator can advise me as to whats going on with the octo when in the air. Craig tell me what setup you are using your end...you did say an octo? Ross

3 days ago Gunter, I had to go 80-90% throttle to lift off....I started thinking the worst..motors not man enough, lipos not man enough or wrong props! Then a guy on here called Craig mentioned that I might have AH enabled, I was sure it wasn't...but he was right, it was on :( Sorted that out...

Maybe Dave has sold it back to Quadcopters ;) Ross

I was shocked by how responsive these things are!!!! I found if I let go of the sticks that she went right & forward slightly, not sure if the trimms on my transmitter will sort this or if she has to be 100% level when starting here up..eg left stick, upleft & then down right to start motors...

Damn, wish I had seen this before Dave, thanks for the link. Ross

Well I managed to get her up, so we filmed it with a Panasonic HDC-SD9 & the air vid was from the same camera. we didnt activate the gimbal as its purely a vibration test flight. When I was uploading the film to my computer I thought I would check out the OIS setting....it was on!!! This camera...

2 x main lipos packs 1 x camera downlink lipo 1 x ground station lipo 1 x tx

thanks Bart, I can honestly say its different, yet I feel quite happy flying her, even more so than my trex600!!!! Im trying to edit 3 mins of video, but my main computer keeps switching off....far too memory intensive for the old girl & my notebook has premiere but for some reason want do HDV...

She's skinny enough & I prefer them to have a bit of meat ;) Here's the results of todays flight. 3 mins & it drew 1450mah from each 4000mah pack...so thats 5 1/2 - 6 mins I would have thought? Problem was cured that I had yesterday..I had AH enabled :) Ross

You've got working well...that's an understatement..its bloody brilliant. Ken I messed about with RC helis for 3 years & NEVER had anything that could compare!!! if Mk comes half as near as that I will be happy. The days when its not so clever have you ever recorded the atmospheric pressure for...

Spot on Craig, she flew like a goodun today, thanks for the heads up on the AH...that WAS the problem. Less than 1/2 throttle & she was off the deck, I couldnt even go to full throttle as she climbed quite fast & shocked me. I actually had her in the air for 3 mins exactly today & that was 40%...

Thanks Mat, looks like I will need 4 lipos per flight then :( Ross

Thats probably the smoothest video I have seen to date from an MR aircraft Ken, superb. What FC are you running? Ross

That's my main problem Ken...lack of funds & of course lack of knowledge. The Mrs set me a finacial target, which I passed some time ago now ;) What is the main difference between the 2 AH's? Also what advantage is there to having vario AH on during normal flight? Thanks mate Ross
