Tail vibration, tail wags or blows out suddenly. I had some tail vibration in mine from the start. I put some lube in all bearings and tightened the feathering shaft as it was very loose. I used some tri-flow to flood both main bearings and soaked up the excess with a peice of paper towel after a couple of flights. The lower bearing had some black residue when I soaked up the excess so flooded it again until it came out clean. This cured the vibration and it worked fine for about 20 more flights. Started the vibration and blow outs again but flooding didn't help. I pulled the main shaft and found the bearings were very ruff. They are 2x5x2mm so checked my bearing supply but had none. I found the Boca 130X set I got for my 130X and it came with 4 blade grip bearings. They are 2x5x2mm so used 2 of them. Now flies smooth as butter with more power then when new. I think the stock bearings aren't very good and may be why some people are getting tail vibration from the start. Pull the main gear down and see if your rotor turns smooth to a slow stop. Any jerky stops and the bearing are bad.

You should just buy a new one and send the old one back and demand a refund. That way you don't have to wait.

Loving my nano. Finally, just what I always wanted for over 20 years now (minus an airwolf fuse), back when I had to settle for getting the "small" Kyosho 30 DX.

Is this thing small and light enough to where a direct drive brushless setup would work?

Don't know, just kinda went crazy then stop working. Not sure if it is the board or motor or both. So when I get both parts I will install them. I think I will wait a little longer between flights because I was doing eight flights at a time back to back plus some of my old batteries stop working in this bird. I really do love this little guy a lot and hopefully will pick up another on Monday. Can't stand being without it.

Are there any better throttle and pitch curves than what is in the manual for 3d?

Also, what are people finding to be the most broken parts? I'd like to keep some stuff on hand.

Thanks

Feathering shaft is the only part I really need to keep stock of since i changed the boom to solid 2mm carbon.

A linear pitch curve and flat throttle for idle up is great for 3d. If it is too twitchy for your liking around midstick add some expo to the curve

I can hear the tail motor pulsing, so I guess it is either a bad tail motor (can't maintain rpms) or a bad board

Really sux because I can tell even with the tail wag it's gonna be a lot better than the mcpx 2...
Mine wasn't wagging with the sport blades but when I switched to the bullets it has the exact same wag you describe. I did lube it and put a new tail blade on it in between, haven't had time to monkey with it but since it wasn't doing it before perhaps it's fixable... I'll post if I make any progress.

NO, if the board is bad, the worst that can happen is the full voltage of the battery is sent to the motor, which is the same thing as being at full throttle. So, while a busted motor can melt the board, a busted board can't really melt the motor.

I'm running no expo and no dr. Linear pitch curve and a flat curve. Flies great, thanks.

Thanks, some close calls and a bit all over the place. it's a lot sketchier trying in a tight space. I think indoorheli has a video of his mcpx doing loops in the bathroom.

Just passed 50 flights on mine and the tail motor is on it's way out. Probably just the brushes jammed up or worn out, but it takes a flick with the finger to get it started up. Didnt wanna risk it shorting out the board, so just soldered on a MCX2 CCW motor and it's back up and running great.

The only part on mine thats well worn is the feathering shaft...LOL, but for inside 3D, besides the nasty blade tracking and slight shakes, it still does ok. This bird is tuff! No sense in really replacing the feathering shaft since the next one will take one hit on the fridge and look the same.

Blade scrapes across the hardwood floor are just addicting, as is inverted ceiling landings
If you dont have one of these and are on the fence about it, your wasting valuable smile time.

I havent hit the throttle hold in years, because with the larger helis, goin in with throttle hold verse trying to correct both do a lot of damage, so usually i go for altitude and correct when it's up hi and safe. With this thing in the house, throttle hold, smack the counter, pick it up and off she goes! Unbelievable.

If you know how to fly, this thing is an indoor dream, if you are just learning, it is a forgiving indoor trainer. I cant really say anything bad about this little guy. I cant see anybody not enjoying this heli.

There is only one thing I can say that's bad so far about this heli ... THEY SHOULDA COME OUT WITH IT YEARS AGO

It's everything I was hoping the 4G6, Genius CP and mCPX would be and more, I mean seriously inverted flying if my office, crash it against light fixture and literally just put it right back up in the air?

Yo pinch me cause this is crazy! Practice anything you want and don't really worry about crashes on a CP??? WTH

I agree! This thing is amazing. First CP heli (well, I did have a 450 but I was too scared to do anything with it other than hover). Within the third pack I was doing loops, rolls, and inverted hovering (hunderds, and hundreds of hours of sim time might have something to do with it). Nothing be afarid to break it does wonders for progress!

Thanks Jasmine, I appreciate the feed back. I will first install the new motor with the old board. If I am lucky and the board is good, then I am ahead of the game. Going to get another one on Monday. Just too much fun. Also, if it starts acting funny again, I will just replace the motor in hopes of saving my main board.

I must have missed your vid nice flying quick reactions Yeah it was me with the bathroom vid..being silly. I thought I had a huge learning curve with the mcpx and that is nothing compared to what the nano has already taught me

Just an FYI you can use either mcx motor if one works, just reverse the polarity
