Hello Hugh, That little fan draws ~140mA at full pelt so not very much. However, my thinking was if the fan can lower the MOSFET junction temperature by even a few degrees this lowers the Rds(on) of the transistor and makes it more efficient. I have not worked the numbers but my gut feeling...

Good afternoon everyone, I have been making a few modification to the Quad ahead of an upgrade to 5000mHa 4s battery and possibly an upgraded motor set. I was a bit concerned the Q-Brain 4 x 25A ESC I am using might be pushed a little hard by larger motors. The FETs inside can handle the...

Hi Andy, I have just noticed that you didn't get a reply which is totally not cricket. I personally must have tried and used about half a dozen different video editing pieces of software. These range from the high end stuff from Adobe down to the cheaper end of the spectrum. The high end...

Whoops, apologies - forgot to hit publish after upload Is it working now ?

We finally got some ok weather .... I shot a little video this afternoon :) comparing the output from the two cameras mounted on the Quad. The main video was taken using the Boscam HD08 on the two axis stabilized gimbal featured on an earlier post. The inset video was taken at the same time...

Well they are ok motors but not in the same ball park as the Sunnysky offerings. I had a look in more detail at the Sunnysky ratings and 'I think' I would be ok using my existing 25A ESCs. The Sunnysky motors do pull current than would not be healthy for my ESCs but that only seems to be the...

Hi Hugh, Yes, you are absolutely correct those Turnigy 2217 are 3S motors well there appears to be no specification for 4S. Sorry my post wasn't very clear I was planning on using my original set of motors EMAX MT2216 which are rated 3s - 4s http://www.emaxmodel.com/views.asp?hw_id=1292 I...

Thanks for the information Hugh ! Sounds like weight wise we are very similar - my Alien is currently 1740g but with a smaller 3300mAh 3s battery. I currently have Turnigy 2217 motors and 1047 props fitted. I am going to make a step change and order up a 5000mAh 4s battery and also a 12V UBEC...

Evening everyone, I have put together a charging solution for the LiPo batteries I currently have. I investigated the option of a single large charger and then adopt a parallel charging technique or secondly to use multiple smaller chargers. After considering cost and flexibility I decided on...

Good job Robert, I hope my first stabilized video proves to be well ...... as stable :) If I can fly the thing long enough without crashing you never know ! Cheers, Dave

Hello Hugh, Yes, the SimpleBGC PC utility is closely coupled to the firmware version running on the gimbal control board. So if you try and use a later version of the PC software relative to the firmware on the control board it (the PC software) will not be happy. The version I have on my...

Hello one & all, I have been busy today - after all the normal family stuff I was granted a few hours play time so decided to get stuck into fitting the gimbal on the quad and re-building where necessary in order to achieve balance. I now have a complete model with two cameras, the Boscam TR1...

Hi Hugh, The internet (ebay) is awash with the gimbal we both have or very similar variants. I think if the gimbal works well out of the box then leave it alone and don't attempt to upgrade the firmware. I have played with both cracked and third party firmware and they perform in a very...

Hello everyone, Guess what - I have generated another video :) Having taken delivery of my imported two axis gimbal I subsequently realized these gimbals are cheap for a reason. The firmware they are running (well the gimbal I have) is a hacked version of the official firmware. The physical...

Hi Hugh, Yes indeed I did have RTL setup on a hot switch programmed up on the APM flight controller and had even tested it. However, I don't have a great deal of Quad flying experience and the loss of control took me completely by surprise. Had I been flying in a more responsible area with...

Good evening one and all, OK, I have been acquiring some more parts for my quadcopter development and as promised making a few more videos to add to the diary :) After much reading and thinking I have purchased the camera for the Quad. Quite a number of people of gone for the GoPro offering...

BIRD DOWN ..... WE HAVE A BIRD DOWN IN THE CITY (black hawk down) :) I have lost my cherry and had my first crash ! BE WARNED - SIMPLE MODE & ROOKIE PILOT BAD COMBINATION. Ok, I was doing a spot of hover practice in the garden near my workshop. I was flying in stabilized mode with simple...

Hi Tarek, I am hoping the camera will be comparable with the GoPro, at least when fitted to a Quad. I think the DJU Phantom looks like a very nice model but I have no experience other than with my own build. I think in terms of price the DJI will be a similar price to an own build, maybe...

Hi Tarek, Yes, the GoPro (especially the black addition) is an excellent camera with impressive spec. At this point I couldn't really justify the expense of the GoPro. In the UK they are around £250 which I think is very overpriced - but it is the market leader so can demand a premium price...

Good evening everyone, Tonight I flew the mission detailed in the last post again but this time I fitted a Boscam TR1 camera to the model. The camera was not on any type of gimbal but just on a platform with rubber supports. I have now balanced the props which made a big difference to...
