Brushless Nano Battery Lead Upgrade

Lately, there’s been a number of threads created where Nano CP X owners who have installed a brushless motor on their heli, have learn that upgrading to a thicker gauge wire improved performance noticeably. There is a noticeable increase in pop acceleration and less to no bogging.

I wonder how much of it is due to the thicker gauge wire or if the improvement comes from the thicker wire being more tolerant of a sloppy solder joint?

I went ahead and took a photo of the recommended wire gauge side-by-side in case you are curious.

20ga silicone wire, 24ga silicone wire, 24ga(?) servo wire, 26ga(?) stock Nano CPX wire

I always like using servo wires. Copper is a good conductor and the servo wires are usually made of copper. The only thing is, it’s insulating sleeve isn’t as heat tolerant as the silicone wires. Another property that I like with the silicone wires is that it’s really flexible.

Here’s some weight difference between 24ga silicone wires versus what I think are 24ga servo wires. The stock Nano CP X leads of the same length was added to compare the weight. Every gram counts when modding the Nano CP X for performance.

I think the most important thing is having a good solder joint. To ensure there’s no impurities in your solder joint, you have to use flux. A hot iron and flux will make a solder joint solid and keep the resistance low.

Make sure to properly insulate the solder connection. And I like to stretch a piece of shrink tubing so it fits over the connector. This ensure you don’t fatigue the soldered joint.

New Landing Skids

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.

Nano CP X Goblin Inspired Carbon Fiber Landing Skids

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?

Blade Nano CP X Brushless Guide

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.

Update 2013-03-09:
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.

Blade Nano CP X Square Tail Boom Mod

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.

Here’s some photo of the result. I am so happy I can simply put in a new tail boom or fabricate one by cutting to length.

Blade Nano CP X Canopy Revisited

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.

I found that the following Walkera canopies are the same shape, with just difference in color and decals.

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…

First off, we got the Genius CP, in a very easy to see Orange-Yellow paint scheme:

Next, we got the Mini CP in it’s metallic red/burgundy scheme. Looks nice and has a white under belly:

If you want something blue, kindda along the lines of the alternative Nano CP X canopy that Horizon Hobby has available for the Nano, here is The Walkera Super FP option:

Finally, for those who wants a bright green…you can purchase the Genius FP canopy:

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.

Blade Nano CP X Canopy

Do you need a new canopy for your new Nano CP X without having to pay the $12.49 Horizon Hobby charges for a replacement? Well, you’re in luck because the Solo Pro and V911 canopies fit perfectly on the Blade nCPX. You can find these replacement canopies for as low $0.99 at oversea retailer. Or check eBay for dealers in the states.

The top mounting position fits perfectly. Then you can leave at is and punch a new hole for the lower mount, or trim the lines for a custom look.

This mods pros and cons list:

Pros:

  • The v911’s canopy is much, much, much more durable over the stock nCPX. Weighs ~2.25g. The Solo Pro canopy weighs ~1.85g. (Depending on how you trim.)
  • very affordable. MyRCMart carries them from $0.99. Or order from Banggood.com
  • alternate look, lines to your nCPX.
  • Easy, simple mod!
  • No leftover holes that says, look…I re-purposed a canopy from another model.
  • Paint scheme and words removable with nail polish remover so you can repaint as you like.
  • Bonus: A good way to hide your new purchase from the significant other. Disguised as a cheap $20 chinese FP heli.

Cons:

  • Heavier than stock (1.58g)
  • No Blade/nano CPX branding on the heli.

Here’s a red v911 canopy as it is.

Very easy, moderate trimming and you can reshape the canopy to your liking. Here’s one variation. I didn’t punch the hole yet. You can angle the canopy up or down before you punch that second hole. It fits over the battery tray perfectly, and you can still insert the battery all the way forward.

An alternate view.

Here’s what it looks like with yellow Nine Eagles Solo Pro styling. It’s very vibrant and actually matches the nCPX yellow tail better than the nCPX’ own canopy does.

The Solo Pro’s canopy material is similar to the nCPX’ stock canopy. The v911 canopy however, is a very durable plastic. That’s the one to get for durability. Or get them all. It’s cheap!!!

Here’s the Solo Pro in blue. Also known as the Soars in some parts of the world.

The blue v911 canopy looks like this:

The v911 also comes in it’s default Black and Orange pattern that reminds me of Trex RC helicopters.

There’s also the yellow and white version of the clone v911 heli, which doesn’t have the intake scoop at the top.

Anyways, hope those are good leads to finding cheap canopies that fits your new Blade Nano CP X. They take a much better beating than the stock nCPX canopy. Important if you’re going to be doing 3D. :)
