Hi,thanks for the review,is the head block bolt and washout arm bolts loose or not sized correct? The head block should be tite on the main shaft,hope you can get it sorted out and let's see a flight video

Seems they drilled the hole in the main shaft too large for the selection of head bolt. Or bolt too small.
I gave it a good extra crank last night and I don't dare tighten it any more...it is still loose.

I don't like it...but everyone else is flying them fine. Though, I don't know if they have a slightly loose head either.

If that's a "teaser", should I be expecting even harder 3D from this heli? Haha great flight and thanks for sharing! I might get out today for my maiden...had our first snow fall that stuck to the ground.

was struggling to get the ESC calibrated with my Taranis...had silly throttle hold on
WOW haha had to laugh just a bit, but also cried a bit because it prevented me from getting the 20min of flight time I had set aside for this morning.

Oh well...I'll get out there.

So I class finishes up. I take a deep breath, zip up, and head out to the foot ball field with just over an hour of light to fly. It's already about freezing out...
Strap on the head cam, boot up the radio, grab a pack annnnd realize I forgot to attach the battery strap after I modified a Rakon one with some strategic velcro.

So...I hustled home and, at my amazement, had time to fly my 4 packs. Recorded every flight. I will plan to do so as I did the 230 S....nearly all 103 of them only missed a few. I won't keep them all but great for the memories.

12.5 degree pitch limits

1
The first flight was with no canopy and my longer airsoft pack.
I only flew at low head speed, which I left alone.
I set the Talon to have a 65 Motor start rate and a lower idle up rate but can't remember the idle up rate...slower than necessary.
It went great, got my jitters out that flight for sure. It was flying around pretty good and I cut that flight shorter than 3min. Don't remember doing any pitch pumps the first flight.

2
Second flight was the Zippy Lightmax 1000 25C...not really sure how it will hold up to high head speed hard 3D.
I fit the canopy on with ease and took off...WITH EASE!
This heli takes off and lands very very well.
SO, this flight I stepped it up to what I call IU2 since my N became an IU1.
Sounded great and was more stable/responsive.
Gave me more confidence than I've ever had.
I zipped around a bit and did some pitch pumps...might have noticed the tail oscillation then, but I'll have to watch the videos to dbl check.

3
Third flight was the Zippy Compact 1000 40C
Kicked it up to IU3 after taking off.
Transition was very smooth, this heli is less intimidating than it seemed in the videos.
I however have only 30R65A65E for rates, all with 25 expo for now.
I can not fit the canopy with this pack, just barely can be modified though.
Did some harder pitch pumps and it would give a jerk from +to- but a harder jerk from -to+.
Then the tail started oscillating pretty good, drop to IU1 and it went away.
Went back to IU2 then 3 and it seemed ok so I avoided pitch pump "testing" and just flew around quicker.
That's when the tail oscillated during a wide right rudder turn but it went away as I lightened up on the stick.
Gain is too high? Doesn't sound like the out of balance issue Gambino had.
I threw it inverted a couple times too.
Rates need to be higher than 65 if I'm going to toss it around that for sure.

4

Final flight was the Nano-tech 1000 25-50C
Just smooth slower flight after the tail oscillations.
Flipped it inverted a few times and did some nose in then landed.
I got the canopy on with this pack but just, so the canopy doesn't wiggle around...that's good I guess haha.

I didn't crash...and only had one person randomly walk into my flight path...need a legit place to fly that's near by not 20+min away. 20min isn't bad but for a busy guy with a place to fly 5min away, it's a bit out of the way.
I'm pretty darn satisfied and I know the tail oscillation can be sorted either through gain or maybe it is a balancing issue.
There is something def not right though, the pitch pumps are nasty and that tail oscillation.
I will post the flight video compilation as soon as I get it wrapped up.

I'm gonna feed the doggies, do some digital electronics assignments, then edit that footage!

Fast oscillation. Like it didn't want to catch itself then started over shooting until it reached a steady fast oscillation which only varied about 10 degrees total. Wasn't a 180 degree out of control wag haha.

Was scared it would get much worse but had enough cofidence to idle down if it ever happened bad so kept flying.

I totally kept reading the "...or was it turning on u?" As "turning u on?" Haha...um no it really wasn't turning me on in the slightest.

Haha....sounds like gain! Go down 3 or 4 points for iu2....well idk how taranis is setup but make sure lowering gain affects iu2 position on your tx

Also i would still balance tail blades with that headspeed. Take mains off and run her up try different pieces of tape if it gets worse then u go to other blade experiment. Its all trial and error. I got my tail pretty smooth until i get some carbon fiber tb

Well idk how it works for taranis but yea in my case its 68 for gyro so if i had that problem i would go to 65 if still there then 63. Only little increments at a time. And im assuming it would be your gyro in tx, or whatever taranis calls it tail gain? Lol. Spektrum tx u can do fm1 fm2 or gyro sw. It sounds like your there just lower a few points in gyro

Taranis has no gyro menu I believe.

I was just reading the BeastX manual and I now see the TX gain adjustment. Spektrum does it through the gear channel. That's also the channel that I programmed Panic into....
The 270CFX manual said Channel, Gear, Gyro...then the Panic was said to be the gear channel with -60% - +40%.

Damn maybe that's my my gain was off...idk.
I tested panic on the bench and thought it activated properly. Though there is an IMPORTANT not below regarding SAFE and Rate-Mode. I don't have time to read about it anymore. Been distracted from homework enough.

I'll get back to you in a while but I appreciate all the input you have in regards to adjusting tail gyro gain with the TX if Panic is also being activated on that same channel.
