A friend of mine gave me a small box of spares for his old mCPX. Can the nano use any of the spares from the mCPX?

Tail rotors and tail motors

Sweet! He's got some mCPX tail booms and motors in the spares box. Thanks!

The coiled wire definitely is included in the effective length, infact, if you were to straighten it out, and place it across the middle of the heli, you would get better signal from it then wrapped around a post, but it would have no support.

The apparent signal drop, where the rotor stops and lights turns off, I feel is a brown out. This happened to me regularly while my main motor was dying. I am pretty certain it would've been due to a fatigued motor drawing too much from the board, therefore the board shut down to compensate. (Save from cooking). Replacing my main motor solved this issue for me, and it hasn't happened since.

Weak points on the nano, I do not feel include the main board. Mine shut itself down each time I was too slow on the TH, and when my motor failed. They do however include; tail boom, landing skids, feathering shaft, and main motors. (My opinion only, and not limited too). These are the items I am going to upgrade or mod, to hopefully spend less down time.

Same here. The times where I was slow on the TH especially when my main motor started to die my Nano would reboot in a way. I would have to put the left stick to the bottom and flick the TH a time or two and it was good to go again.

I don't know how people make these canopys look so good. My first paper canopy for my nano is complete and looks terrible. I'm sure you don't get work like Daryoon makes on the first try, but... MAN it's hard!

Check it out. Yuck!

Looks like hell, but its pretty hard and will probably protect the little heli pretty well.

Having said that you've clearly found "some" pitch value that lifts but doesn't bog the motor down, that being the value that you use in your fixed pitch tests. You also have found a lower pitch value that gives zero lift even at full throttle. How does it work if you set the pitch curve between those values? Maybe it's too coarse a control.

I suppose for sports/training flying the ideal would be asymetric but flat bottomed blades. Is that what the MSR (not X) blades are like?

Thanks, Tony S

Well, the FP MSR and MSRx blades are definitely optimized for zero pitch, but I didn't try anything between 45 and 50 (50 being zero pitch) I bet I could optimize it a bit more since 50 in the radio may or may not be exactly zero pitch.... I would think it would be unlikely its exact, but I don't think its far enough off to worry much over (I have already taken them off the heli)...

You are right that undercambered airfoils do best at low speed. The MSRx blades are actually just barely undercambered, while the MSR blades are significantly more undercambered, and wider, and also a bit longer. They are optimised for a lower head speed, which is why it (the nano) is able to fly with so much lower power draw with the MSR blades. The MSRx blades are made to run a much higher head speed than he MSR blades, (shorter and narrower) so you have better control, but at the cost of increased amp draw.

The only downside I found to the MSR blades (other than not being good for aerobatics) is a weird nodding/bob my nano did with them installed, but I think that's probably due to the fact the blades were well used and chipped, since the MSR I took them off had the bob too, (but not as bad) The upside was MUCH longer flight times with the stock battery, plus the ability to fly with my old 150mah 12C packs..... For hover practice indoors, they are great. For anything else, probably not...

I have no doubt you found a bunch of posts of users complaining the board is weak but that has not been my experience. I've crashed plenty and only banged up one canopy and one set of skids so far. I've been stuck indoors for about 4 months now in a gym so I'm definitely not currently flying over grass.

It's kind of a generalization for someone to post that approx 5 crashes would take out a board. It would be very hard to crash something this light and damage it much unless you stalled the main motor, kept full throttle on and the over current protection failed until some chips on the board burnt up. I haven't seen OCP fail on any of mine.

What's a bunch? 20-30-40 out of 1000's of owners?

I really don't think there's an issue with weak boards.

Anyone tried extending the tail boom? I'm about to make up a solid carbon boom and am considering extending.

Tail still holds solid though, quite impressed.

my tail boom is cracked and twists when I fly but the tail still holds better than my mcpx. I don't really see what an extended tail boom would add to the equation except making it's cog off. I am definitely considering a solid one but don't want to make my own. I love the hop up on the mcpx and wish horizon would offer a solid replacement for my nano. I am being lazy though, I want to buy a plug and play part rather than spend a little time making one for a tenth of the price myself.
