Thanks for condolences
Should have listened to that lil voice. But it hovered great....set head speed by ear on Kontronik/THR Curve. When I picked it back up to move out; it just rolled on its nose from about 5 feet.
I picked up pieces, checked servos...went flew my 700. 6 flights and club got a new member today. Still a good day.

Rubbed a beer on my nerves at dinner and made a late night parts order.

***I love this hobby.

FBL Issue
I installed the Linear Hall Servos. (Got a screaming deal on them from a fellow RR member.) On websites it says they may move around a lil on the ground.
Setup the Skookum...gyro read inputs and Graphical interface followed the sensors. When doing the preflight checks the swash didn't move alot. (Followed commands to correct for movements. But.....it didn't make large moves to correct.)
*I chalked it up to the servos being different.*

WRONG>>> it hovered great. When I gave it some elevator to move out...it rolled over.
Got in TH HLD quick. No teeth gone but it cracked gear in the webbing, broke blades pitch link, pitch arm, tail boom, torque tube...ect.

***IF preflight isn't perfect...keep it on the ground. If you are afraid to put the canopy on.. prolly have some doubts. LOL.

I have got to get one of these. I was jonesing for one when they first came out but the lack of response from the heli community held me back. And hoping someone would have a sale!
Now I see a lot of differences in setups. 12s VS 14s, High HS VS Low HS. Long VS Short blades.
Are there any motor choices that can do it all? Generally I prefer lower HS than most. Neither my TDR or Rave 120 are over 1900. And I love my TDR at 1600. So I will probably start with a long blade 12s low HS setup. But it would be cool to be able to simply slide in a 14s pack and switch flight modes to run high HS. Thinking 1100-1200 for a low HS and 1700-1800 for a high one. Thanks

using the same setup as I used in E720's, hacker 400kv on 12 cells, but with the smallest pinion. Modes of 1100/1400/1600. Plenty power,.. everything comes down cool after each 12 to 14 minute flight. No, that's not a typo. Using telemetry for battery capacity and landing after the 4000mah alarm goes off (5000mah packs).I fly a mix of rpms, switching back and forth a lot in flight, hence I wanted the capacity telemetry since a timer doesn't really do the job due to the massive differences in current. At 1600, the tip speed is equivalent to what my E700 would be at 1850, so although 1600 sounds low,.. it really "goes" at that.
Interestingly enough, a friend was watching the telemetry on the transmitter during a flight and we were both amazed at the 1100rpm mode. It's enough power to do smooth 3D assuming good collective management, and he said inverted hover was 8 to 9 amps (bumping back and forth) and it never went to 30 amps even in piroetting flips and such.

This setup will go 1750 but it's not needed for my flying style, hence the 1600 top rpm. I want to explore the lower end more but only have less than a dozen flights on it, so not there yet.

big blades must be even more efficient than I thought. Stuck a gps sensor in it this week and tried it this morning. We had a lot of wind so can probably subtract 10~15mph from the top speed number, but it recorded 171kph which is 106mph, and only at 1600 in the highest rpm. probably 90~95 with no wind. PLENTY, and only on 12S at rather sedate rpms.Maybe I need to slow down the top rpm also

I got mine up and running a couple days ago.
Flies very nicely indeed, super flat piro's, very linear but light feeling.
Flies like the logo 700 should have...

I went with:
14s 4400
Kosmik 160
Scorpion 5035-380 and a scorpion 4530-450
770mm mains
120mm tails
Vbar

1600/1900 rpm.

The 4530-450 with the 11 tooth was too much for the 111 tooth cnc main gear. It was turning it into snow regardless of lubrication or mesh.
The tail ratio is a bit slow, but I've got some rotortech 135mm tails for use with the 810mm at lower rpm.
Very impressed so far, it comes in 1 pound lighter than my goblin 770 competition with a similar power setup.
If I can get the tail dialed in and the gear train holds together, I'll be selling some other helis.

I started with trim flights this weekend with good results. I'll post pics soon. My model has good power on 12S with a Comp Pyro800 400kV on 11/115 with 800mmm Spins. Like big airplanes, big helis really fly well. This really is a nice model. BTW, be cautious with that long a tail blade at any higher headspeeds with the 5mm tail shaft. Tail blades are rarely even close to being chordwise cg corrected, so hub stresses really go up with longer tails. 120's are about as high as I would go unless you plan to live at 1000-1200 rpm and have a huge tail fin to protect the blades.

I'm having a heck of a time tuning the tail.
Tail steps out 3 inches and then works hard to get back in line, on hard collective reversals or pumps.
I'm not getting anywhere tweaking the vbar so far, it may be a case of a slightly too low tail ratio combined with the kosmik governor...changing to the v-gov/yge or upping the tail ratio would probably fix it.

Ben, I will send you a blank cheque if you can talk kontronik into putting an external gov mode in the kosmik. The kosmik is a great piece of hardware, but it's governor is hands down outperformed by the v-gov running an esc optimized to use it.
It brings the ability to tune out tail artifacts without making the governor response mushy.

Search for John Benario on here. I'm using speedup gears he made for the 720/820. I went that route since I fly some low rpm flight modes (1100 on the 820 in slowest mode, just slightly higher on the 720). Using his speedup gear puts the tail up to 5 to 1,..actually just a touch over it. Using 115's on the 720 and 120 tailblades on the 820. Both CGY750 (on 820)and GT5 (on 720) lock the tail perfectly. I had previously ran the 720 at 1180 to 1250 in the slow rpm flight condition, as the tail wasn't perfect but tolerable there. Now it's locked and even piro's at a consistent rate when moving around.

Thanks for the heads up Gary. I Pm'd him about doing a 25 tooth tail drive gear.

I believe the ones I'm using are 24 tooth. He mentioned one time he could "fudge" the tooth spacing to drop it by two teeth but no more. that would change from 26 to 24, and result in 5.04 if I remember the numbers correctly. I'm too lazy to look them up now <G>

I pulled up a couple emails from a few weeks ago. Sounds like he's gonna be out of town for several weeks, then moving out west for his employer, so it may be some time. Darnit, I wanted to send him an E700 gear to pattern a speedup from. guess it'll have to wait.
