    Why can't you run your 6s packs on one? make it 12s. Or even better yet run 10s and make 2 pairs of packs with your 6 and 4s and you can charge one set while your driving the other. I have run the 3994 on 12s and its a monster, motor, batt and esc temps all under 100F after a full set of packs (2x6s/5ah) and will drive a 50+mm prop, the X447 I had on it did almost nothing and the 450/3 still didn't get it over 105F. Make sure you get a decent size hull if you try it tho, its is way too much for anything but saw use in anything under 40" imo.

      I believe you. I had a feeling that thing was monster motor My packs are all different mAh and C's and as well as not having to buy new packs I'd like to not having to buy HV-esc's. I'm cheap, at least right now. I really like the M180 and for the price it's unbeatable (imho). So, 6s at the very most. For now.

      Something in the 40" range - check!

        12s speedy is less than the 180: http://www.hobbyking.com/hobbyking/s...oat%5FESC.html

        Keep in mind with twice the voltage you need half the amps. But I'm sure you motor and esc combination will work nicely together. Shame your packs aren't compatible tho.

          Yep, I know. I think the 80A constant rating is a bit on the low side for these big motors. I guess those HV-esc's were meant to work together with low kv 3674-4074 territory, but that's just a guess. If Im getting let's say 4000 watts out of a 5692 1000 kv on 8s - Im pulling 135A = magic smoke.

          About the LiPos. Yeah, you kinda outgrow, learn new things etc. and in the end you're just buried with stuff you have no use for.

          I still do run a cat with twin KB 3674 2700kv on 3s although I'm changing direction to HV and low kv. It hauls (and whips up a rooster tail of doom!) 84 km/h = 52 mph. This is on the fifth run the same day and I hope I can tune another couple of mph out of it.

            I think your getting the wrong idea about HV, I wouldn't call 8s HV, I'd call 10-12s HV. On 10s that esc if it meets it's rated power is capable of 3000w continuous and 6000w peak, allowing head room say 2500 and 5000, on 12s it's 3500 and 7000, so allowing headroom 3000 continuous and 6000 peak. Realistically on 12s if you were conservative on the prop and it is capable of what they rate it to it should run a 5692, I wouldn't personally try it, my intention was more for the 880kv 3994 motor on 12s which is 4000w peak. I'm gonna buy 2 and check them out, could make a cheap effective 12s controller, might be cactus on first use. Only one way to find out=)

              Well, it's the manufacteres of esc's who often draws the line on 6s, not me And you need some cool battery charger etc. It adds up.

                The 5682 arrived to day. It's one huge S.O.B! Where do you guys find motor mounts?

                    someone has a thread in the special services, he might be able to fab one for you, or go to FC.

                          Well.... can you tell if it's a 4 pole or 6pole motor??

                          You might be able to see the magnet segments if you remove the front cover.

                          Thats up to you.

                            Thanks!

                            Will get back to you about the poles. I turned the axle one 360 and counted 18 "notches". Turning my 4-pole 4074 gave me 12 notches, if that counts for something?

                                I would assume that means 6- pole, but you never know.
