215 sport with a solid tail?

[Epoweredrc]

I wish the tail on my Oxy 4 was as god as my Oxy 2.. My oxy 2 is the best micro sized heli i have ever had/set up/flown. I was very very late to the trex 250 crowd but did have one for a little while, tail was never solid on it.

the blade 180s, my last one with a stretched boom was the best one but just this Oxy 2 flys so great its my fav heli right now. I hope the Oxy 4 will become a fav soon if i get all the bugs out of it, the esc giving issues then tail issues. i did stretch the boom and put the other pulley on it. it still flys nice, just a couple of bugs to work out, have a small tail wag that wont go away, at least the tail is holding in backwards flight now.
oxy 2 at 4600 and 5000 flys great

oxy 4 at 2700 and 3205 love the lower headspeed of it, i can do everything i like to do at the 2700 on 3s

i'm running a spektrum 3060, there's a wear mark on my tail rod from rubbing. It's definitely not a silky smooth tail when rubbing on the guide.

Mechanical setup and electronics.
Lynx 1611 5500kv,
Lynx Servo DS-895-HV Aluminum CNC Case on cyclic
H3060 on the tail.
113T main
11T pinion
41mm tail blades. Tail is silky smooth (on its side, drops by itself without pushrod).
Vbar Neo (6.3 firmware)
HW25A ESC Governor mode.

Settings
3 banks: 65%, 75% and 85% (from circa 5500 RPM - 6500 RPM)

I've tried a lot of settings on the VControl Gyro (inc advanced / expert)
I have P gain up to maximum of 120 and I gain close behind at 80 or so.
I have messed with most of the other gyro settings including D gain (up to 10), A and B stop etc but to no avail. I cant find anything specific re the latest 6.3 vbar settings so am unsure how to best tune it (Mr Mel stuff is up to v 5.1 I believe so largely out dated).

Mostly what I am getting is a wag on pitch pumps. If my I gain is too high, I also get nasty judders but always, always, a slight wag (about 30 degrees to the right at any headspeed). I read here that most folks running similar electronics require no additional settings so this is very frustrating.

Is this an issue with the 215.

Can you please advise / help with my setup possibly? I have ordered some larger tail blades (KBDD 45mm) which I will try but surely Lynx would never release a product requiring such extreme measures to get flying properly...?

Did you ever get your tail kick sorted out? Sounds like you need to add some pre-comp to your tail.

i trimmed the flashing off of my plastic tail blade grip balls, it made a noticeable improvement.

I recently upgraded by plastic tail slider to the metal one. Wow, what an improvement! Too much slop in the plastic one. An essential update IMHO

i dont' have this heli any longer, but after another try with spirit on my xlpower, i realized i just don't like or know how to tune spirit tails.

while on spirit, the tail on the xl520 was behaving similar to my oxy 2. I've switched to a brain fbl and all my issues went away.

i'm wondering now if i would've had a better time with my oxy2 if i had just started with a brain instead of a spirit.

I don't think you're the only person who's struggled to get their head around Spirit tuning:

I really do need to get my hands on one to try them out for myself though, certainly a lot of very interesting features bakes into their FBLs these days.

too much work, when brain basically works out of th box.

It's funny - if you read enough posts you'll find someone with everything that doesn't work.

I think that you hit the nail on the head though - there was a post the gets re-posted repeatedly about the best way to set up a Brain tail (and seems to work very well). However it's not the same for a Spirit, but the Brain approach seems to have become the de facto FBL tail set-up approach for many and when they apply it to the Spirit it's not effective.

[myxiplx]

Yeah, Spirit seems to take a very different approach. But they also have excellent documentation, including tuning tips, which I very much like.

yeah, just my experience. But it was 2 different heli's there were behaving the same, sliding into stops.

Tried the Sab 280 tail blades and tail is solid. Just land perfectly or tail will scrape.
