Review: JJRC H36 2.4G 4CH 6-Axis Gyro RC Quadcopter
I always like opportunities to try out new RCMoment sent me this cool little mini quad to try out - JJRC H36 4CH 6-Axis Gyro RC Quadcopter. First thing's first - full disclosure. I don't have any vested interest in RC Moment. They sent me this quad for free. I am not the type of person that is influenced by free stuff. I get asked to do a review, and I will give it my…
LISAMRC ML180 Carbon Fiber Frame Kit – Review
Today we are doing a review of the LISAMRC ML1800 Carbon Fiber Frame Kit. Not sure what LISAMRC stands for, so I suppose it's a 'cool' factor thing. Overall, I'm pretty impressed with this micro-sized quad frame kit. It's well crafted and light. There are some minor issues, but no show stoppers and nothing you can't fix with some spare bits. The following is an unboxing review and observations putting the base kit together. Sometime in…
DIY & Hobby Projects: Parts, Components & Tools Must Have’s
Most people who visit to this site are either DIY'ers, Makers, Hackers, or Robotics / RC enthusiast. For the most part, we all do the same thing - we build or mod stuff for our projects or hobbies. Over the years, experience and repetition has given we wisdom as to what works, what doesn't, and key components that I want to have on hand. I wanted to share a list of parts/components I have found useful for…
Micro MinimOSD – D4R-II RSSI using RC Filter
I'm running a Flip32+ using a D4R-II receiver and wanted to get RSSI into the Micro MinimOSD. Googling yielded other results that did not work for me. After digging deeper, I found this worked for my set-up. The solution is an analog RC filter consisting of a cap and few resistors. The idea is to convert the PWM signal to an analog signal so it can be interpreted correctly. Analog will provide an analog…
Micro MinimOSD – Gray Screen – A Fix
Symptom Summary: With the camera plugged in, the OSD would not display the telemetry overlay and only show the camera view. Then, when the camera is disconnected (power), the OSD would show telemtry, but no camera view. This is a repeatable activity. I also verified that my RX<>TX were connected correctly (was able to see the OSD change when moving the quad so I knew this was working). Solution: Fix: Although this may have less…
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 (or…
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 for…
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 That said, I was flying FPV and decided…
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 to…
