Testing photogrammetry and mapping

Posted: 2017-07-03 | mavic | photogrammetry | altizure | dronedeploy | dji

Testing some of the mapping and 3d/photogrammetry apps out there with the mavic yesterday.

Had some issues with the mavic’s camera focus (was out of focus even when pre-set) so I’ll need to try again.

But - two maps with drone deploy and one 3d model...

Axial Bomber RR10 build

So although I have a couple of basher trucks and one high speed buggy - I didn’t have a good slow/powerful rock climber truck.

Inspire 1 temperature

I send my flight data to flytrex while flying, and I also upload the flight records to healthy drones afterwards.

Both show a graph of temperature over time. Healthy drones explicitly shows it as battery temperature, flytrex just temperature.

Flying sunshade for iPad mini

So - the iPad mini is a great screen to fly the Inspire 1 drone with - apart from one thing.

It reflects.

Time for a sunshade. It needs to work both to shade from the sun but also to shade from the user’s reflection.

So - this is based on what I...

New racing quad

Headed out to Gaustadjordet with P and the Summit and Vorza.

Fun - the summit is better on the snow of course - but there’s just enough ice free for the vorza too.

Snow chains for the summit

So - the summit slides a bit when the snow is icy on top. Just for fun I thought I’d make some chains for it.

I started with a long length of chain. The links are perhaps a bit small but the next size up was too large.

Then - I looked at the wheel...

Flying - Vinland

Posted: 2014-09-21 | F550 | hexcopter | dji

Flying near Vinland (Gan).

Testing a new 9000mah battery (extended life vs. extra weight) but didn’t get to find out. About 6 mins in - the OSD info stopped updating position and then as I brought it in to land - about 3m up - as it was descending - it suddenly flew hard throttle right hitting hard enough to crack one leg (easily fixable) and also throwing the battery out - it’s OK - but I don’t know what battery life I would have had if I’d flown until I hit 15v (I’ve chosen 15v under load as my alarm point). Apart from the leg - it all seems fine but I do wonder why it suddenly lost position signal - it had 12 sat’s showing on the OSD just before.

KK2.0 quad with DX6i TX and orange R615X RX

Posted: 2014-06-07 | dx6i | kk2.0 | quadcopter | spektrum

So - I’ve been running the KK2.0 quad with the Turnigy TGY 9X radio I got at the same time I built the quad.

Thing is - that the radio burnt out it’s battery compartment when new. I replaced the connectors and it works fine - but it always smells newly burnt. Not good right? And I have the Spektrum DX6i radio for the blade quad I have.

The DX6i is only 6 channels - not 9 like the Turnigy - but I was using 5. So that’s OK.

So - I decided to move the quad over to the DX6i radio.

Replaced Traxxas Stampede suspension arms with RPM A-arms

Posted: 2014-06-06 | traxxas | stampede | rpm

Had a slight accident with my stampede (Traxxas VXL Stampede 4X4) the other day - hit a jump ramp at slightly the wrong angle and bust a suspension arm.

After some reading online - most people were pointing out that RPM’s third party suspension arms were stronger - so I grabbed two sets.

Using the Spektrum DX6i radio with the Blade Nano QX

Posted: 2014-05-29 | quadcopter | blade | dx6i | spektrum

So I finally got irritated enough with the radio that comes with the Blade Nano QX RTF (MLP4DSM) that I grabbed a Spektrum DX6i instead.

The Blade Nano QX manual says that you need to following configuration for the DX6i:

  • Acro mode (not heli)
  • Flaps switch should set NORM FLAP to Down 20 (this is for switching the QX in and out of agility mode)
  • Elev D/R and Ail D/R should be at 70% for low rate and 100% for high rate (this gives you a slightly less manic quad when learning)

So - I programmed up the following:

Type and Name

Setup List > Model Type > Acro
Setup List > Model Name > NANO QX

D/R & Expo

Adjust List > D/R Expo > AILE 0 70%
Adjust List > D/R Expo > ELEV 0 70%

Both of these switch to 100% when you flick the respective switch. I guess I could also set a low rate for rudder here if I wanted - but I couldn’t be bothered - yawing isn’t too bad.


Adjust List > Flaps > NORM FLAP > Down 20

Now this says to toggle in and out of agility mode - move the flaps switch from 0 to 1 and back. This appears to work - the LED on the QX switches from blue to red and back.

But - when in agility mode - it stops responding to the pitch/roll stick.

Horizon Hobby support suggested resetting the radio program and starting again - which I did - same result.

Just on a whim - I changed the flaps from NORM FLAP Down 20 to LAND FLAP Down 20 - and this appears to work just fine.

I’ve queried this with Horizon - will get an answer in about a week I guess - based on how long they took last time.

Using GoPro mount to attach FPV screen

Posted: 2014-03-08 | quadcopter | phantom | dji | fpv

I’ve been wondering how best to attach my FPV screen to my phantom radio. I’ve tried the type that attaches to the bar across the back - but they make the kit large and unwieldy. I’d thought to attach it to the lanyard clip mount - but then a couple of times on facebook I saw this mod. It’s easy to do, attaches easily - yet detaches easily for packing.

Mini-quad case layout

Posted: 2014-03-04 | quadcopter | hubsan | blade

This is based on the Clas Ohlson instrument case - code 38-3978. Note that this is leaving their product line - but is being replaced by Clas Ohlson instrument case - code 38-5920 - which looks identical - is cheaper - and I’ve still not ever found it in stock in any of the shops. In the end I got fed up waiting.
