Gemfan folding propellers A few tips when ordering Gemfan folding propellers. #1. Check clearance- This is most important for pusher planes like The Skysurfer/Bixler/Ranger. Sometimes with optional motor mounts you will be able to mount larger propellers. Make certain you can clear the fuselage. You may want to order the next size smaller if you’re close to hitting the fuselage. #2. Make sure your motor can handle your propeller- If your motor is optimized for a six inch propeller and you put on a 7” propeller, yes it will work. You can rationalize that you’ll never use full power. Even with a lower power setting the larger propeller requires more work to make spin. What you think would be more efficient flight can actually be less efficient as it draws more energy and drains your battery faster, even at lower speeds. #3. If the spinner sits on the front of your plane it should cover the front. It’s cone shape is aerodynamic, it helps slice through the air. If it’s going to be used on a pusher plane you’ll want it to be not exceed the diameter of the mount so that it doesn’t add to drag. #4 Do not over tighten the propeller blades. They need to move freely to fold and unfold during flight. #5. Maintenance is important- Make sure your propeller blades are balanced. If they break on one or both ends, replace with a new set. This review was posted on my Facebook group. ( https://www.facebook.com/RCplanes.n.stuff/ ) The photo posted is of a Gemfan spinner and folding propeller on a Radian. I will be discussing how to do this with parts found at Banggood in a future post.

Flysky 2.4G 6CH FS-iA6B Receiver PPM Output With iBus Port Get the right receiver First of all, a warning- If you’ve been using radio controlled for a good long time you may remember back to the FM/72mHz days. Some radios were positive shift and some were negative shift and that was confusing enough. When it comes to 2.4g RC transmitters and receivers, it's much worse. Not only are the receivers not compatible between manufacturers, but sometimes they aren’t compatible in brands. For Flysky, I will share this table with you that outlines what does and doesn’t work. https://rc.305.cz/storage/FlySky_Tx_Rx_compatibility_table.pdf Thus, when you’re buying Flysky, stick with what you know will work with your transmitter. What is PPM? PPM - Pulse Position Modulation -PPM is also an analogue signal, but instead of using a separate wire for each channel, PPM stacks each signal one after another to send them all along the same wire. This makes wiring your R/C Receiver to your autopilot much easier! The PPM port is on channel 1. What is iBus? IBUS is the new flysky serial protocol. It’s a two way communication which means it can send and receive data: one port for servo data output and one port for sensors. This receiver will handle up to six channels. Most planes can be handled with five channels or less. Delta wings usually run on 3 channels. The extra channels can be used for operating cameras for example. RC Helicopters often need a lot more channels and thus require more sophisticated systems. If you’re going into killer FPV setup and are setting up iNav, gimbels on servos and all kinds of other cool things all on one plane , you may want to upgrade your transmitter and receiver package. The Flysky is wonderful for simple application. I’ve seen people using it for iNav. And it can handle most planes if you just want to fly it line of sight or mild FPV. My suggestion is that you always have extra receivers on hand because you’ll never know if Flysky will move on to a new technology that isn’t backward compatible. You’ll want some for future RC projects and in case one of your modules gets damaged. A link to this article can be found on fb.me/RCplanes.n.stuff
