Wow, three minutes per flight, that's all you get with the nano? I am torn between ordering this or the new wltoys one that is coming out soon. If its like their other helis, we're in for a treat. Should be real cheap, too.

Finally my main motor died after about 60 flights, I'm surprised it lasted this long the way I fly and crash the heck out of it!

But I noticed this new motor has a bit more power! Man I'm thinking I should have broken in my stock motor properly, heck my first flight I was pitch pumping and flying inverted just to see what it was made of, this new motor I've broken in by having 2 batts run through it without a load (no main gear installed yet)

Just put a new motor in mine as well, we'll see how it works as soon as the battery is done charging.

I believe the Mini's Tail Motor has internal wire Brushes which are bent and assembled at an angle in such a way that they work best only when the Motor is spinning in a particular direction. Although swapping wires to reverse the polarity of the Voltage going into the Motor will make the Motor spin backwards, I think spinning the Motor backwards will cause the wire brushes wear out faster. Perhaps this crude diagram may help explain why:

/O/

Both wire Brushes (both "/") are bent and angled so their tips apply pressure and have electrical contact with the Commutator (the "O"). In the above diagram, if the Commutator is rotated CW, the springiness of the wire Brushes allow them to automatically maintain slight electrical contact pressure as they "slide" along the Commutator; however, if the Commutator is rotated CCW, the Commutator will "push" on the wire Brushes causing them to become hotter, wear faster, and fail prematurely.

As an example, think how a cat or dog's hair behaves depending on which way it is brushed: in one direction stroking downward from the top of their head towards the legs, the hair lays flat, and the stroke is smooth; whereas, in the opposite direction stroking upward from the legs towards the top of the head, the hair wants to stand up and the stroke is rough. With all the wire brushed Motors I've seen, the wire brushes behave the same way, and have a preferred direction of being "stroked" (i.e. rotating around) the Commutator.

Although the below EatAtJoes video is of a different Tail Motor, starting at 1:35 it shows what wire Brushes look like, how they are angled and bent to make spring contact with the Commutator:

Just ran 3 packs through my nano with a new stock motor, I'm quite impressed! The new motor has more power for sure with the stock battery and I also ran a ThunderPower 160 in it. So far my stock Eflights are more punchy then the TP but this was only the first run on this new pack, hopefully after it breaks in a bit it will be better. Didn't do any Acro with it just hovering and basic forward figure eights. Run time was right at 4 min., plenty of power left after my timer went off at that point

I disagree with some of the others. The nano is a great indoor heli for your intended purpose. I set the dual rate at 50% and expo to 10% and it is very docile inside.

I think everyone does, once they start playing with them.

I was having control difficulties at first, and bumped the expo to 40% (factory recommends 30%). Not better at all!

I have started reducing expo. I went down to 15 and it was OK, went to 0 and it was too much. I went up to 10 then, and will stay there for a bit.

I recommend reducing the expo slowly. Get used to a setting, then bring it down a bit. Rinse and repeat until you are satisfied.

I cracked my boom but it still holds. It is just very flexible, especially radially.

I do have some 2mm CF rod here, so I will probably adapt that soon. But I also have a spare tail boom with motor.

I have a mod, it's in the conceptual stage... I made a mock up. It might not be to scale. I think it might be the perfect excuse to buy one even though I don't have much hobby time at the moment. What do you guys think?

Hotglued the tailboom where it meets the frame. The Hg did not hold and came loose at mid flight, aaaand the landing gear popped off!!! Suprisingly it had very little inpact in control. The tail was 60 - 80 deg to the left.
Those people not breaking this bird arent trying hard enough
Awesome heli

Looks kind of like a flame thrower. I like it!

While this makes logical sense and I have opened many tail motors my motors that I have swapped polarity on still seem to last fairly well. Though they do seem more susceptible to hard crashes.

Did you try a stock length solid boom before adding length?
