We used to do this mod on the old CP Pro and others like it, to install a brushless tail. The board just outputs a servo position for the rudder channel - if we have enough control over what position it outputs then it can be done. Basically, you need proportional mixing, plus gyro correction on that channel, and you're golden. You can do the proportional mixing in the radio, and if you add rate gyro behavior into that, it should work. The existing board might work for a helicopter, but I'm not going to try it because I'm happy with what we have

So you know how to hook up the stick to the 3A ESC? I have the stick and ESC coming from Dylan this week (to shed some AUW). Is there an instruction sheet for how this is done?

My nCPX has the cyclic shakes just like my 130X and I have not been able to cure either one. I got a metal swash for my 130X in today and it completely solved the shakes. In fact it flies 100% better. Rock solid.

Cannot wait for a metal swash for the nCPX!!

Interesting, i never went brushless tail from servo output. I have obly done conversions on micro helis with brushed tails.
Thanks for the info, but I wont try it on this little heli either

Dylan or Topper, both do it for 5 bucks

No going back now..just soldered the board and cut the main power

You may run into issue getting it to flash with the adapter wired up like this.

Let us know how it goes.

why?
I didnt read where it said it wont work tapped straight to the 3n1 signal..do you know it wont work like this? if so ill go the other route...i didnt want to bend that plug would take a bit for me to solder it with not much work area

I guess it isnt too hard to work that little area and keep the plug... I only have one esc right now so i dont want to fry it

It won't hurt, so give it a try.

Early on the BLHeli thread, Dylan of Astroid Design and myself did something similar. We tap into the two points and wired up ground to the connector. And it won't flash. Don't know why since the black point and the connectors are technically on the same trace.

I didn't mean to discourage you from trying. Just wanted you to be aware in case nothing was happening and you start wondering if you had fried something.

BTW, I would look up the post on HeliFreak...but I get a virus warning from Google since yesterday.

Thanks for all the feedback. I went to my LHS (Atlanta Hobby) and picked one up earlier this afternoon. WOW what a great heli. I only have 4 packs through it but was able to do flip and fly inverted. I have to say it's a little faster than I expected and it's very very responsive. Performance seems more than adequate. Overall I'd say it's a perfect next step from my MSR. I will need a few more flights outside in the grass before I take it inside. Glad I went this route thanks again for all the advice.

TOO LATE

I spent another 20 minutes re-soldering. My thought was on the previous that if people are offering a flashing service they have to tap it fast and if so I thought it must be through the standard side port. If that is true and works now I still have my adapter plug with battery hookup intact to try down the line.


The virus thing is only for a single zip on HF so i wouldnt worry about it

I just smoked my main motor. Just over 60 flights. 67 actually.

I was just at the shop today, and now they are closed. Msr main is too big...sad now...

Edit: I Just came in from a couple of packs on the brushless Mcpx out back and I feel better now. I can say two things after that, as it has been a week since I gave it any love.

1. The Mcpx is bigger than the Nano. Just so, I have the yellow canopy on the Mcpx from Extreme with the KDBB blades blah blah, my Mcpx is pretty yellow etc. so maybe it's just more visible, but it sure looked bigger than the Nano just now.

2. Everything happened in slow motion? I was way ahead of it. Supercool. (I mean to say I attribute my new powers to the Nano)

P.S. I obviously agree with the brushless conversions people are doing, and I will be among the first in line when Astroid Designs has an "Add To Cart" ready.

As to the ongoing conversation as to whether or not HH should have come correct on the subject of brushless motors vs brushed, conspiracies aside, what I do believe is that HH does what is in their best interest first. This tends to include good customer service from what I've seen. I am not past understanding bad luck either in certain cases on either side. But one has their doubts about what seems obvious from time to time.

I am calling them in the morning about the motor even though I do happen to have a spare in route, which is why I didn't think to get one at the shop tonight.

67 flights though? I have my IU pitch at H90 L10 even....I need to have a civil word with them about that.

In addition to my previous observations during my evening of larger than Nano flying....I wanted to add that:

The Brushless Mcpx I have is what I consider a mild mod, sort of the way I thought the Mcpx should have been out of the box. Plus the tail-boom which continues to be a bit under sized in my opinion in V2. So it fills the void nicely for the Nano, save for the noise.

My Stock Mcpx V2 just got some action as well though, and I'm a little sad that it felt pretty ghetto just now compared to it's new little brother that just got sick. Enough power still, and maybe I need a new main there too, but ghetto nonetheless.

That's not to say that it doesn't have it's place in my heart because of the progress I did see with it. I feel strongly that I needed to add that the stock Mcpx V2 made me behave like what I consider a better pilot to be. It forces me to fly clean so to speak etc.

Which is a trait that I'm quickly losing with the Nano after just over a week of almost exclusive flying with it.

Last week, I was flying the Nano in the backyard(2nd/3rd day with it), one of my friends said "It looks like it's got it, but it looks jerky." I said "No, the bird is awesome. It's just me suckin'...alllll me...lol." <--We really did laugh out loud there.

I could never have flown so sloppy and carless with my stock Mcpx and gotten away with it. No way not ever. The nano has appropriate power to me. More than is necessary in many cases you could argue.

Longevity however? We'll have to see. Like I said in my previous post, I'm not past believing in bad luck, especially my own, but I'd like to see more than 67 flights out of my next Nano motor. And I wouldn't mind being made comfortable with the idea that this won't be the norm.

Having said all that, for me, it seems like the Mcpx always ever should have been what the Nano now is.

I should have ordered a second like some of you smart and able fellas did.
