How To: Install FrSky DHT 8CH DIY Kit into Turnigy 9x

Given the help provided by others, I thought I’ pay it forward with my spin on the installation of the FRSky DHT 8Ch DIY transmitter in my Turnigy 9x Transmitter.   Before getting into the details, I’d like to credit RCModelReviews for Bruce’s how-to video  as well as for details on how to update the firmware of the D4R-II (to solve the PPM framerate issue).   Although this is primarily about the DHT DIY module...

Prop Storage Using LEGO Technic Axles

I have a variety of 5040 and 5030 spare props.  The need for both CW and CCW props, makes for a mess when trying to find a replacement when you crash and need a new prop. Given I break at least 1 prop per flight (I’m learning flips these days!), I wanted a quick way to access either size or direction of prop.   Look no further to your LEGO Technic collection for axles...

Quad Landing Gear Meets LEGO Shocks

After a few hard landings, the carbon fibre landing gear that came with the ZMR250 frame were done.    After researching different solutions, I gave the zip tie concept a try.  The solution entailed creating ‘loops’ out of zip ties and mounting them to the quad legs.  However, they sagged under the weight of the quad only a day or so after mounting them.  This caused the quad to be out of level – not a good thing...

Quads: Why you need Failsafe and a LOMA

I finally got my 250-sized quad ready to fly.    The last 2 things I did were to add a LMOA (Lost Model Alarm) and configure failsafe in Cleanflight.  Luck was on my side yesterday as Murphy’s Law kicked in when I took the quad out for it’s first full flight test in a nearby field.   Admittedly, I still consider myself a noob with much to learn…  That said, I was flying FPV...

Quadcopter – Enhanced Lost Model Alarm

Just 24 hours earlier I built my first Lost Model Alarm.  Not being satisfied with good enough, I’ve built an enhanced version.  Of course, you could just buy one, but where’s the fun in that?!  As mentioned in my original posting, I wanted the alarm to have multiple modes.  First, I wanted to be able to have it triggered while the TX is on using one of the available aux controls.  Second, I wanted it...

DIY Quadcopter Build (MultiWii / NanoWii / Qbrain)

If I didn’t have enough hobbies already…  I’ve just gotten myself into the world of quadcopters and flying.  I’ve never flown before.  My RC experience is limited to 4 wheels on the ground.    Navigating with 2 sticks and learning the world of yaw, elevation, pitch and throttle has become my next challenge.  I’ve wanted to learn how to fly for some time, so here we I’m not going to re-create the wheel...
