hi all, mine arrived today, flys great but after a tiny while tail starts drifting left very slowly, its correctable with trim but i thorght the tail help rock solid on these?

i know my honeybee v2 did the same thing when the battery started wearing out.

have i received one with a dodgy tal motor or is this normal, its a slow drift left that needs correcting now and then, but adjusting trim does stop it.

any feedback?

thx

While hovering, the tail motor responds to both right and left input. But when I introduce some ff and right tilt, the tail motor 's input sometimes gets ignored and acts as if it is not getting any input. The tail motor doesn't stop working, but it wont continue to turn as instructed until I stop giving forward and tild input.


To give you a better idea, I will start giving it some forward and right tilt, and then some right tail to get a cirlce going...about 60-90 degrees into the circle's circumference the tail quits forcing right , and my heli goes straight until I stop the forward and tild input...then and only then will the tail start getting TX input again. I feel like I'm repeating myself but it's an odd issue so I want to be as clear as I can.

What could this possibly be? a bad gyro? I know it's not my transmitter because my other v911 works just fine with it...so it must be something wrong with the heli.
so nobody can throw some wisdom my way about this?

I don't know as much about these as some others here, but I would have to say that should be expected as the battery drains. Not sure I've ever flown a FP that didn't do that to some degree. I actually don't like a "hands off" hover. I like a little pressure needed on the tail stick to hold steady. Makes adjusting for this a little more second nature to me.

just had a proper flight, what a great little heli , flys everybit as good as my mcpx that i sold cause im not interested in 3d. and in mode 2 its very responsive stunning for 24 lol.

The stock 120 lipos dont last long do they, i have 4 300mah nanotechs that i used on the mcpx and ive noticed the connector is the same, Would i be best off modding the skids to take these packs or are there any other better packs i could use ?

thx guys

I've already tried this several months ago. They're too heavy.
You won't increase flightime.
The v911 is very sensible according to additional weight.
But try it yourself

You might want to try some micro bearing oil from LHS on rotor shaft. Is it getting hot too quickly .I test mine on lower lip " hope one never super hot" I think the drift problems is heat and lower volts combined. Make sure rotor blade is not pushed in too far. I never noticed mine until 2/3 batt. Also I trimmed mine after about 45sec after the turbo extra punch of a new battery settles out . Reports are that a few tail motors fail fairly early.

I feel envy when I see my Dad enjoying retirement. I won't be one of those people that stops working. Wish I could be, but I believe I would die much sooner if I stop working. Anyway, GFY (Good For You) Enjoy every day. Life is good.

I haven't tried his exact mods, but I've tried an improvised version, which is simply tighen the flybar screws so they stay on plane, that has the effect of flybarless as far as delayed blade pitch commands, but still maintain the stability of the flybar inertia. The blade pitch is then controlled only by the swash. This makes the heli ultra sensitive to stick input, that's why KKDDMM mentioned numerous times you need a programmable tx to fly it. Also, I noticed in his photos he added weights to the blades to compensate for the flybar removal. and punched holes in the blades, which causes the blades to spin faster due to lost of lift; the added spin rate provides still more stability. I surmise he found that combination thru trial and error. I'm sure kkddmm would share more details, but he's said so himself that his limited command of english prevents him from doing so. (However, I think he has a blog in Japanese on another forum, if that helps.)

The "9958/v911 Tour Over America" continues to rack up the miles adding California, Nevada, Illinois, South Carolina, Massachusetts, and Louisiana. Those photos and the entire collection of visits to 36 states can be found on my blog page. Here is a tease...two big guys and a little boat.

My V911 is quite nice. I think the remote is nice and the 2 batteries and dual charger are great. The motors are noisier than my 9958s and the controls are more sensitive and responsive. On take off with a fresh battery the throttle seems to take a minute to stabilize as the heli climbs are drops the first few seconds I guess before you can maintain a steady hover. Overall a great product!

Does it happen in the beginning or end of flight? Your pack may also need some seasoning (a few charges to for peak run time). Also make sure the tail blade is not on to tight.
