While rceccleston and the rest posted a few log files for fixed throttle curves, sharing a log file on its gov.
Have gone from gov to fixed but immediately went back to gov again. No doubt fixed has longer flight times but gov has better power consistencies if your battery is up to it. Going 12s for either is not a bad move and a good effort by rceccleston for starting this thread with lots of info.
Lipo: Turnigy 3000mAh 30-40C
ESC: CC 85HV
Motor: Scorpion 4025-630

Balance mind, can I ask what setting did you use for your gov ?

After lurking on this thread for about two months, I'd like to offer thanks to rceccleston and the others for showing how easy a 12S 600 setup really is. I just put two sets of packs through my new 600 ESP in FFF and basic aerobatics, and I must say "WOW". The reserve power is nothing short of overwhelming. I'm coming from a .50-powered Century Falcon, and the quiet flight belies the strength of this combination. My wife even noticed that the heli does not really need to "wind up" to tap into the excess power; this has been a behavior I've associated with nitro birds when the engine might not be optimally tuned.
I have a 600 ESP, with CC 110HV, CC BEC Pro, 4025-630, and 35C 3000 mAh Turnigy packs. I'm using the Align GP780 (for now), and have noticed that this gyro likes higher headspeeds. Down the road, I may get a Skookum to achieve the FBL configuration. I have DS610s on the cyclics, and a DS650 on the tail. The ESP was purchased from Kirk at PerformancePlusRC, who was very accommodating in providing the exact kit I needed to achieve this.
Thanks for continuing my addiction! :)
Well done. :thumbup:

Recommend manually specifying 630kv with a timing of 5.

Yes.

Did specify 630kv but when u do a read back, the software automatically change it. Seems like no adverse effect yet with all my flights and log.
I think i tried timing of 5 before and the temperature was slightly higher and I could not feel the difference in power. But worth trying again since I could not remember more reasons why I have choosen 3.
Maybe you would like to share your data and your experience in setting the timing of 5 or your overall gov settings.

just a quicky lads, the 2 motor bolts that come with the scorpion dont appear long enough to get sufficient thread when going through the align aluminium mount, did you all use longer screws? and no washers came with it either, surely you need a washer under the heads dont you, am just about ready to dremmel a flat spot on the shaft for the pinnion grub screw, anything i need to look out for? thanks guys, tony.

Hi Tony,
I used two longer bolts I had with my old motor. I thought the same thing as you did and also used washers.
I didn't dremmel a flat spot on the shaft. Not sure this is needed. I just snugged up the grub screw and used locktite. Never a problem with it and I regularly fly at 100% and do lots of high-collective stuff w/ the bird, just because its fun. :D
Be very careful when you tighten that grub screw that you don't strip it. Otherwise, it will be a nightmare to take it off. I speak with experience on that one!
I'm in favor of a flat spot...just need a little something for the grub screw to grip, not something as deep as what Align does on the stock motor. Just my own opinion.

Thanks carlos, yea think I need them longer ones and washers, I have the mikado 13 tooth and it's a tiny grub screw when compared to the align ones, And can imagine it's a right pain if it rounds off! so that got me thinking is it ok to cut off the top of the scorpion shaft allowing the align pinnion to fit? I've got a few different size align ones and they all have the larger grub screw, don't like the idea of drilling all the pinnions out to allow them to slide down, one cut with the dremmel and the motor shaft is the right length! What do you think? Tony ps can't wait to get this all done but want to take my time and get it right.:thumbup:

Dunno. On my first pinion on this motor, I used a 12T Mikado pinion. For some stupid reason, they use the tiny grub screws, same size as for my 450 motor. The Align pinions use the larger, huskier grub screws. In any case, I tightened it down and applied the necessary loctite.
About a week later, I decided to try 13T pinion. I went to remove the 12T pinion and stripped the grub screw in the process. Took me over an hour to remove that pinion, with lots of direct heat and some "convincing" with a pair of channel locks. That's after drilling out most of the grub screw (I didn't want to damage the shaft).
I'm firmly convinced that with enough loctite and "snugness" of that grub screw, a flat spot is not needed. Again, my opinion only, based on trying to remove a pinion that was only secured by a tiny grub screw!

LOL! We both posted at the same time... and both remarked about the tiny grub screws on the Mikado pinions. :D

Anyone running a 12s setup on a Jive80HV with no bec?

Just bought my 12s power plant.. Scorpion 4025-630kv along with a set of 6s 3300mah lipos from HobbyPartz.com. I already had the CC HV110 ESC and BEC Pro. These lipos wiegh less than the Hobbyking 6s 3000mah and can be bought here in the states for $57 a piece.. http://www.hobbypartz.com/83p-3300mah-6s1p-222-30c.html

Very timely, especially since HK is having some shipping/processing delays right now!

Tell me about the processing delays. I ordered my batterys 7days ago and they are reserved but still processing at hobbyking. Apparently they are moving warehouse and expect 5 day delays. Obviously that is not the case for me as I ordered at exactly the wrong time.

Man, I've been waiting for Turnigy 40C 3000mAh 6s for a month now. A lot of their batteries in this range are out of stock. Insult to injury, I crashed my T500 twice, killing both of my 6s 2600mAh batteries, so I'm grounded until these things finally arrive.
too many guys going 12S :)

hi guys, any idea where the best place is to tap into for the power supply to the hercules bec pro? in the diagramme that comes with it it shows it joined at the point where you connect the packs to the esc, now im not keen on how that looks, (messy) in my opinion, so can i do it another way, ive looked at mr eclesons pictures and cannot see how his bec is fed! but i do like its neatness and am trying to replicate it. tony.

For my BEC Pro, I cut a strip of insulation about 4 mm wide about halfway down the battery side leads from my CC 110HV. I then soldered the BEC Pro leads to these points, and then slid heatshrink over that. I used a single strand of copper wire to bind the connections and hold them in place so that the solder would flow into the joints.

I'll post a pic in the morning.
I made a parallel connector so the ESC and BEC plug into the Y harness and the single end connects to the battery. That way, I can unplug the ESC when I'm testing the electronics, etc without ever worrying about the motor firing up. For clarification, I soldered a male on the single end, 2 females on the Y end, and a male on the each end of the ESC and BEC, respectively.
