Ouch, that crash hurt. I guess another case of down is up and up is expensive?
Yep, up is expensive. LOL, I'll have to remember that one.

Our LHS has a Nano out as a demo, and that's a great idea. It really helps to sell them when customers see one buzzing around the store.

Not that I would know anything about that.

More indoor action :)

Bland nano (1 min 51 sec)


Just messing around. This thing is so much fun inside. Can't get enough!

Thanks everyone for the carbon fiber how-to's and tips.

What a great community-the members here share information and ideas so freely. It helps take away some of the frustrations that can manifest in this hobby.

On tail booms, I've been holding off on a solid boom until my last one breaks.
So I coated this one in thin CA and it seems to be helping. So far no boom splits.
Also you can beef up the strength of your canopy mounts with epoxy to prolong a frame replacement. I use the steel epoxy and it works good.
I only slam into walls I guess because I have yet to break the skids.

Haha. Yeah. He probably crashed BECAUSE he was videoing.
I suck when I know I'm recording.

I split my boom last night attempting tic-tocs over my driveway...oops, I used thin CA and a little carbon tow twisted around the boom, it's really light and stronger then stock, I still have a spare boom so going to a solid rod isn't really needed at this point.

Starboard Servo DOA

Just picked up a Nano BNF on Monday. Programmed my DX6i and it binded (bound) up right away. Performed my pre-flight surface control check...dead starboard servo, and I mean dead.
Connection check, no joy On a positive note, she powered up fine and was impressed how smooth and quiet she is, but the the servo failure makes it a no-go
Hopefully HH will ship me a new rig as this one never achieved lift-off...
NOTE TO SELF: NEVER buy from an LHS that does not swap out for a valid reason...should have made the 40 mi. roundtrip to one that does and has a dozen BNF's on the shelf.

The reason I ask..... I'm now on my third motor. I got about 60 flights on the first that came with the heli, then only about 50 on the second one. Performance was great while they lasted, but I'm not going to be buying too many more at $12 each - no matter how great the heli is.

I'm not anxious to go brushless...........
Mine died before 40 flights (and i did wait a couple of minutes between each batteries). Just received my new motor, flew two batteries and noticed it doesn't have any punch at all. Just like when I first got my nano.
Did your two replacement motors did the same?
Does a brushed motor actually need some time before it runs fully?

Can't wait for the BL solution to be released either.

Both of mine did. Somewhere around 5 or 10 flights the power picks up, and a few more flights and it gets really good...

I put my third motor in late last night and on this one I'll run the motor at quarter or half throttle for a few batteries to see if I get any more life out of it, and based on the longevity of the first two motors it won't take long to find out

I'm not anxious to go brushless (although its a very cool project). I'd rather find a souce for a $6 replacement coreless brushed motor that'll last over 200 flights with as good or better power than stock - I'm looking......

Good to know. Thanks. Let us know if you did such a motor! Considering mine lasted just one week, either BL or cheap coreless solution suits me

I have a spare motor on order at the LHS, just to have as a backup. My buddy there told me that I should 'Properly' break it in. He explained to me that the brushes in the motor are not properly set to the curved commutator. And there can be a thin film of oil between the brushes and the commutator. What he suggested that I do, is connect the motor to the main board (but don't physically install it into the frame), and then place the motor in a glass of distilled water (very important to use distilled water), and run it for the length of a full battery. I thought he was crazy! I've heard of people doing this, but being an electrician for most of my life, I know that electric motors and water DO NOT MIX! But he reassured me that it was perfectly safe, just don't dump your whole helicopter in the water of course. He said what this does is that it will remove the thin film of oil between the brushes and the commutator, and allow the brushes to form around the round commutator creating a much better seating connection. And I know that's true, we did the same thing with larger motors as an electrician, we just didn't use water, we were able to get into the brushes and use sandpaper to achieve the same desired effect.

He also said that by placing the motor in distilled water it gives the motor a load, and helps keep it cool. I should also mention to run the motor at full speed for a full battery.

Again, this should remove that film of oil on the brushes, and with the brushes now fitting better to the commutator it will have a much better connection, and power output should be better as well.

When we get new motors, and you notice that it takes a few flights for it start to perform well, it's because the brushes are wearing in and starting to form around the commutator creating a better connection.

I've never done this, again, as far as I know electricity and water do not mix! But I will be trying this with my new motor tonight. I'm not going to install the motor yet though, I'm going to use stock motor until it goes dead, then I'll install the new motor. I'm just stocking up on parts to take with me out to sea.

Electricity and pure water mix just fine - water is an insulator actually. Where it becomes a problem is when your water contains ions - then it can be a conductor. It can also do physical damage to components because it is an insulator/resistor, it can cause a local current spike, melting components.

That is why you use distilled water for breaking in motors! "De-ionized" water is fine too.

Sold my mCPX, want this Lil guy next!

Will also want a solid CF boom and do a BL Conversion when they are available Plug N Play, based on the early demo vids I have seen in this thread already. Sounds like Dylan is on it....

Bumber! HH should send you a replacement, they are usually pretty good with customer support.

As for the LHS that you bought it from, I don't think I would ever shop there again. I'm a stickler when it comes to customer support, and if I don't like the support I get at the closer LHS, I have no problem driving the extra miles to another spot.

I'm a firm believer in supporting the LHS, I figure that we are pretty much forced to buy everything that we use in our hobby from China in one way or another, so I do what I can to make sure that someone locally gets my money too.

If I have to order something from HH (because LHS doesn't have it in stock), I call my LHS and have them order it for me, that way when I pay for it, they make the profit, not HH.

But if I buy something from them, get it home, it don't fly, they don't replace it. SCREW THEM! They can go out of business for all I care.
