Nice. Congratulations.

Please more info, e.g. Motor

, ESC, Servos, blades etc.

Thanks

Thomas

Jeti Mezon 130hv (vbar gov/ collective precomp 25, cyclic precomp 65, otherwise default values)
V-bar 5.3.4 pro
MKS hbl950/980 (I had problems with shaking with less precise servos @1300rpm)
Xera/Xnova 4025-560 w/13T for 1250rpm
6s5000
Rail 696 (again, because I have them. I really want some VTX 697s or Helix 695 for this bird)
I2RC tri-tail w/ 3x 95mm (A must have for this headspeed to have the shown tail performance)
Logo600se w/BennyTRD single piece headblock (old "3D" head dumping, newer SX style head is more stiff from what I understand)
Lynx LX1654 690sx swashplate
Lynx LX0127 - Logo 600 Boom Holder

I also found that the green Trueblood dumpers were too stiff for this build so I'm running some Mikado o-ring dumpers I had but I don't actually know which hardness. I need to look at the data logs again but I think the highest peak I saw was 62A which on 6s, should put the 4025-560 at or just beyond it's peak efficiency point. Either way, I wouldn't really recommend any other motor for a build like this as I'm fairly certain the Xera/Xnova is the best.

I forgot to add that I'm running the 690sx blade grips so I could use 5mm screws to secure the blades. The regular 600 grips would probably work fine but the combination of spacers AND bolt hole bushings can be really annoying.

I have pretty similar project although I started with 550SX. My head speed for it is 1300rpm and it flies great with that. I can do all tricks I know (not many but anyway, piroflips, funnels etc). Of course I want to go lower HS and my goal is about 1100rpm but for now it bogs if not careful with cyclic. I did not get that many flights before winter so I need start testing again soon and try to figure out how to get it keep head speed little bit better.

I'm little bit relieved by your highest peak amps because I do not have telemetry and was bit worried with that YGE90, although it has not been at all hot.

My setup:
696mm+115mm Rail
Xnova 4030-560kV
YGE90LV
Mini Vbar
Torq BL9080 head
Align DS655 tail
Gens 4400mAh 6S 45C
Pinion 12T M1 6mm
Main gear 106 teeth M1

2620g (5.8lbs) without battery
3320g (7.3lbs) with Gens 4400mAh 6S 45C

The 4025-560 or 4025-670 will be more efficient and you should be well within their ratings on 6s.

From my research, 1100rpm it will fly ok, 1200 will start to get "sporty" and 1300 is just flat out fun.

I'm probably going to set mine for 1250rpm instead of buying a 14T pinion.

Flew it 4 or 5 times at the Heli Spring Fling this weekend and 1250rpm was perfect. So far, I haven't really found any bad flight characteristics. It cruises around very nicely and handles higher cyclic rates really well. I'm really excited to get some VTX blades for this helicopter as I think they may be exactly what this helicopter needs to take it to the next level.

A few people were actually shocked when I told them after landing that I was only running 1250rpm.

I also updated the parts list above to include some Lynx upgrades that I forgot I had on it.

I did a pair of test flights today to get a better idea of flight times on my setup.

Smooth 3d: 9min
"drone" flying: 15min

By drone flying, I mean smooth, all upright medium speed forward flight with smooth turns. I also spent some time hovering as I know that requires more power than forward flight.

From my previous experience, I'd guess an average of 7min flights if you "beat" on it.

Nice. I found it had a bit more pop with a smaller flight pack like 6s3300. CG is off but it hardly matters with a such huge disc and light build. For drone/scale style, you can double up on flight packs in parallel for some impressively long flights!

When I get aggressive with it, I know the limitation is the blades. So, I pre-ordered a pair of VTX.
