I want to share the landing skids I design and cut out by hand using a dremel. Guess where I got the inspiration. ;)
I had some leftover .8mm CF I used for the mSRX brushless mount so I cut my first one out of that. I need to find some thinner, probably .5 or .6mm CF and it’ll be perfect.
It’s mounted to a MicroHeli mSR lipo cage.
The upper horizontal brace is designed to help stiffen the stock Nano frame, as well as obscure the main gear to give the look of a 450+ class heli. It’s also angled to give nicer line once the fuselage is on. Together, it’s almost like it’s ready to pounce into the air. LOL The lower proportion and curves are very similar to the heli that was the source of inspiration.
I will install it on my Nano with the Wild brushless Nano CP X. So plenty of raw power. Muahahahaha
What do you guys think?
Many hobbyist on the forums have been enjoying the Hubsan X4 micro quadcopter. Now that Traxxas is bringing that quad to the US market under then guise of the QR-1, many more people will get to enjoy this tiny little quad copter.
It weighs 8.23g and is a direct fit on the Traxxas QR-1 for those of you who like the black/white look of the X4 fuselage.
Some reference links.

I just got some GWS EP5443 props in from Banggood. Users on the HeliFreak thread mentioned that it improved performance of their mQX. RCGroups also has a couple of threads (New GWS props for mQX and EZ v929 Performance Prop Upgrade) about these GWS props, and most say it’s an improvement over the stock props. So, I have been wanting to try these for a while now.
I got mine in from Banggood for about $1 a piece when ordering 3 or more.
The first users of this prop on Helifreak said the prop did not have an inner ridge that prevents binding on the bearings. However, the version I got from Banggood does have this inner ridge. That’s a good thing, because it allows the prop to properly ride on the bearing.
It has a pretty aggressive looking pitch angle, that changes as it moves from the center to the tip. So some waviness that I thought the props may have been damaged during it’s journey to me. But once compared to the other 16 I purchased, it was evident that the waviness is intentional.
I like the fact that the GWS EP5443 prop weigh 1.68g versus the stock WLToys prop weight of 1.91g. So it’s more similar to the mQX props, weighing in at 1.62g.
From reading the thread, the general consensus is the EP5443 prop is a vast improvement over the stock WLToys prop. However, I see mention that you must balance them first before using. It was refreshing for me to find that they flew fine out of the package. The prop tracks well. I also took off the gear so the shaft can spin freely on it’s bearing when held horizontally. The balance of the prop seems good when tested that way as well. Not certain if the ones carried by BangGood are better than the ones people are buying from GoodLuckBuy.
Anyways, enough of all that. What is my subjective opinion after flying with the new prop? I put them on my v949 and took it outside to put a couple of lipo through it. It was breezy and cold for San Diego, but the prop performs really well. It seems to be all improvement without any negatives that I can see. I didn’t crash the quad at all so I can’t comment on their durability. The v949 with these props on feels very connected to my transmitter stick movement. I like them a lot. And I will put these on my quads of this size.
I also like how different it looks. The props looks very aggressive. The only thing I wish for is the props in red. Advantage Hobby listed white versions. That means one should be able to dye the white props to any color. :) We’ll see when they get them in stock.
Edit to add:
I do find some of my GWS props can use a little balancing. I just pull off the gear and see which side is heavier. I put Kapton 1cm tape in the middle of the lighter blade. On the topside. So far, it seems like 3pieces of tape is perfect.
I just finished putting together a step by step guide to upgrade your Nano CP X to brushless. Using the Dozuki software available for free on MakeProjects.com. It’s the same software that iFixIt uses, which allows you to generate a PDF, or XML of the guide at anytime. It’s also a living document, so anybody can add to it to improve it.
Best of all, you can download the Dozuki app for the iPhone or iPad, and it’s formatted like a manual. So one can be at the workbench and have the iPad mounted on the wall to refer to as you’re modding.
Well, that’s unfortunately. MakeProject is going through a makeover. So the guide is down. Doesn’t seem like they will be using Dozuki’s platform so it’s uncertain what the guide will look like once it’s ported over to their new system. Will update once I get more info.
Just received my Syma X1 flight controller. Ordered from Banggood on November 26th and it just got here. If you need things right away, either pay for express shipping or find an alternative source. But Banggood’s price is usually pretty good on stuff you don’t need right away.

Weight between the two board…
If you’ve flown Blade helis, you would know that they often use 2mm round CF tubes for their tail boom. To keep the tail rotor aligned to the main shaft, each end of the boom is keyed. In the shape of a D.
The tail boom is one I often fracture or break. Horizon Hobby does not sell replacement CF booms by itself. One has to buy the entire tail assembly for about $15. Many of us hobbyist simply purchase 1 meter CF tubes or rod, and cut to length. This is much more economical and keeps more money in our pocket.
Since learning to fly 3D with the Nano CP X, I have fractured more booms than I care to share. And I am sick of needing to carefully file the D shape, making sure not to remove too much material from each side. On top of that, one have to ensure that the flat part is on the same plane on each end of the fabricated tail boom to ensure the tail rotor lines up with the main shaft. It was a nightly ritual that I am done with.
I know some people have solve the issue of broken tail boom by using a 2mm round solid rod. Then they wrap the tail wires on the outside. I personally don’t like the wires wrapped on the outside. During crashes, the enamel coating can be rubbed off and the resulting short will burn out your tail FET. Using solutions like CAT5 wiring just seems to be heavy and clunky on the Nano.
Personally, I wished the Nano CP X uses the 2mm square boom that the v911 uses. It has more meat to it and there is no need to make the key at each ends of the boom to keep the boom from getting out of plum with the main shaft. Plus, it’s easy to purchase replacement boom for the v911 heli on the cheap that is already in a good length. In fact, when the v911 first came out, I purchase a bunch at $0.50 each but have not fractured the tail boom of the v911 yet. It’s the only heli I own that I can say that about.
Noticing that the Turnigy FBL100 and HiSky FBL100 heli both uses 2mm square boom, I purchased a spare FBL100 frame. Cut the rear portion and epoxied it onto the Nano CP X frame. It was actually very easy to do and line up since the flat surface mates to each other securely with epoxy.
Previously, I posted on using v911 and Solo Pro canopies as alternatives to the pricey Blade Nano CP X ones Horizon Hobby sells for $13/piece. On HeliFreak, some Nano CP X owners experimented with Walkera canopies and found that they can be fitted on the Nano CP X with little modifications. One good thing about the Walkera canopy is they are the same weight as the stock canopy, once trimmed to fit the Nano CP X. Plus, it has the added advantage of being molded out of one piece of plastic and is very durable. See the video below for proof. And they are about half the cost of the stock Nano CP X canopies, with a few different colors to choose from.
Isn’t it hard to decide on which canopy to order when it’s often hard to get a clear, large photo of the canopies? HacksMods to the rescue…
Here are the Walkera models and the primary canopy colors…
And for those of you who dislike the Walkera branding, you can do what I did. I scrape off the decals with my fingernail. But later found that I can lift it in one piece with an xacto knife. Any sticky glue residue, you can use CA accelerator to remove. (You did know that CA accelerator does a good job of removing sticky adhesive residue right?)
Let me know what you guys think in the comment section.
Update: After using the canopy for longer. They aren’t as durable as the video below makes them out to be. I get cracks where it impacts the battery cage on my Nano. And the cracks gets longer if you don’t tape it. It’s still more durable than my stock Nano canopy. However, it’s not as indestructible as I had hope.
The v911 canopy on the other hand, is thus far indestructible. And I’ve put it through much more crashes than these Walkera ones. :)
Here’s the YouTube video someone made, attesting to the durability of these canopies.
Got brand new cells and starting to wake them up from slumber. So cycling them a few times at a gentle .6A discharge. Here are the graph so far…
I heard some brands such as Hyperion, if properly cared for, takes 40+ cycle to break in. Wow. I think I have been killing mine in less cycles than that. :)
Will test pulling 1A discharge to 3.8v next.
Many of us in the hobby know that Hobby King has a new transmitter they designed inhouse that is due to be released any day now. Looks like we finally got some high res photos of the upcoming Turnigy 9Xr transmitter.
What’s exciting about this new transmitter is that it will utilize open source firmware, or be flash with one. Hinting at er9x compatibility down the line. Has the programmer plug built in and available inside the battery compartment. Has DSM2/DSMx compatibilities. And, to top it all off… they are aiming it at a $50 price point. The people’s radio they bill it as.
Supposedly the POTs are better too. Not sure what that translates to. All based on rumors for the past year. We’ll see once they start shipping and reviews fills up the forums.
Anyways, a post without photos are boring.
This beautifully lit and captured photo makes the radio look very professional indeed.
Here’s a closer look at the center area.
And here’s a look at the rear connectivity and glimpse of the module bay. Hobby King is working with FrSky to release a compatible module that makes use of the popular FrSky protocol.
Here’s the render of the rear module and the connectivity necessary so you can use the built in antenna. Much better thought out than the coaxial cable on the Turnigy 9x.
