Got my logo 600 flying, and all i have to say is WOW. It makes me look like better pilot. This is my third flight, and i'm finally comfortable enough to fly my normal routine (fff, flips, rolls, rainbows, tic-tocs, etc) no crazy 3D stuff but i do bang on the sticks a bit. I have to say, the 600 never even sounded like it was trying no matter how hard i pushed it. Below is my setup and data log for anyone who is interested. It appears i may be able to share 6S 2650-3000 packs with my logo 400 and trex 500.

Logo 600 Vbar
Edge 603 FBL blades
scorpion 4035-500 with 12T mod 1 pinion.
castle creations phoenix hv 45 ESC
Turnigy 6S 2650 20C (two in series for 12S)
external bec
9452's and 9256 on tail
headspeed governed at 2000 rpm
11-12 degrees of pitch
AUW 7.50 pounds

After flight, all components are only about 120F, if that in 36F weather. I'm not data logging headspeed at the moment, but in comparison to my other birds that fluctuate no more than 100 rpm under the most severe loadings, i would say this does that or better by ear.

Overall, i couldn't be happier and can't wait to really wring it out this spring.

That flight was 5.3 minutes long and i used pretty much all 80% of the pack. I'm thinking about going to two 6S 3000's that way i can easily push my flight time to 6 minutes and still split the packs for my trex 500 and logo 400.

Honestly, even at 5.3 minutes flight time, i was happy. the blade loading is very low and doesn't take much power to move around. I think thats why the lower headspeed still feels very "poppy"

I 'am sure rpm is little or your battery C is not enough. I fly my rex 12S. My rex weight same my logo 600. 2200 rpm with 4025 560kv motor I make 71 amper maximum. 3000 Zippy 30C My flight time 5.5.

Is your comment because my amp draw is relatively low?

My first flight (1900 rpm) i was getting spikes to roughly 75-80 amps but i increased headspeed and decreased pitch to get the feel more to my liking while decreasing max amperage. Like i heard someone say once, pulling amps is easy, the trick is maintaining headspeed. The batteries could be better but seem to be holding there own.

Yup, it's doing fine just warm post flight. I find most people overspec escs. I called castle to make sure and they said that the rating was for average draw and could easily handle 4x spikes (180 amps or so)
plus nice not to have the extra weight

Can you post some pics and videos on your L600.It's kind of hard to find that your running CC 45HV ESC on 12s and still doing them maneuvers that you have mentioned?.

Sorry, don't have any pictures or videos, but i assure you, my normal routine consists of :
tail down tic-tocks
sideways tic-tocs
tail down rainbows
sideways rainbows

various stationary flips/rolls

fff backflips (kind of a ugly wall)

climbouts normal/inverted

I always set up my helis to be as efficient as possible. Rule number one is keep the headspeed at the minimum possible to do the maneuvers you like well, as well as pinion as low as possible to maintain that headspeed (lower pinion yields more effective torque to the rotor, thus using less current to keep the head from bogging). Using a higher pinion and governing down to your headspeed WILL give you increased current in ALL maneuvers. YOur average current is heavily driven by headspeed, and effected by what manuevers you do and how often you do them (constant "crack" flying will push your average up quite a bit)

that said, i've worked very hard to be smooth and easy on the collective, even during the most aggressive manuvers. If i ever go full pos/neg collective, its only for a split second to get some "pop"

Thats just my style of flying, i like to keep it as smooth as possible as i find that most difficult.

I've talked to several other folks who have used the cc phonix 45 HV on a 600 E bird on 12S. I have to admit, even though the numbers work out, i was still a little bit leary but so far, so good. I'm even thinking about going to a 11T pinion when they come back in stock to increase my system efficiency a bit more and keep my 2000 rpm headspeed.

Just curious, do you guys have any data logs to compare? I'd like to see what kind of a data log thermaled your hv 85 just so i can keep an eye out for that on my 45.

whats the worst that could happen....

Honestly i though about it and if the ESC burns up i can still auto down....

I'm mostly judging from the esc temp to see if its okay, and its generally no warmer than the motor/battery, probably about 110F. I"ll have to keep an eye on it as it warms up though, was flying in 35F weather.

just an update for anyone who is interested. Running the same setup at 2000 rpm and roughly 12 degrees of pitch. just got some 6S 3000 hyperion g3 packs put in series for 12S. love them so far, much more powerful than the turnigy's.

pushing 70+ amp peaks, and yup, still on a hv 45!

Are those 3300? or 3000. It says 3300 in the graph.

Looks good. The governor held not bad. Also it's amazing for a HV45.
