The Hobby King 2.4Ghz 6Ch Tx & Rx uses 8 AA batteries and they don’t last very long. It is a great radio for the price, but is a lot greater when you run it with a LiPo battery and it is an easy conversion. I converted mine to use the Turnigy 1450mAh 3S 11.1v Transmitter Lipoly Pack which was designed for this exact purpose.
The Hobby King 2.4Ghz 6Ch Tx & Rx can be modified to remove the detents for more precise throttle control. This definitely helps me control my quadcopter.
The Hobby King 2.4Ghz 6Ch Tx & Rx has to be about the cheapest transmitter / receiver combination out there. At $22.99 plus shipping from China, it is quite a bargain. What’s more, it works! I am using it now with my FH-X46 quadcopter. I haven’t been able to find a lot of documentation on the product and wanted to share what I have learned. Here are some of the mods and features I will be covering in a series of blog posts:
- Modification to remove the detents (the little clicks when the stick is moved) for more precise throttle control
- Modification to use a LiPo battery instead of 8 AA batteries
- How to configure the transmitter with a custom throttle curve
- How to connect the receiver to a flight control board
Carbon Fiber Frame
I recently purchased a carbon fiber frame. Unfortunately, the landing gear and cover that came with it were made of cheap, flexible and very easily breakable plastic. In fact, it broke after landing it just a couple of times. Granted, I am a beginner, and tend to put it down pretty hard at times.
Landing Gear Ideas
Looking around the internet, I saw lots of alternatives. Some people use big swimming pool noodles or cross sections of large pvc pipe attached to each quadcopter arm. I like those ideas, but since I am a beginner, I wanted something tall and wide to decrease the odds of my propellers touching the ground.
Building the Landing Gear
I decided to go with a more traditional sled type landing gear made out of a long piece of 1/2 inch aluminum from Lowes. I paid about $5 for it. See the details on how I built it, after the jump. Continue reading »
