lepard 4082 2200kv in a df 35" pirate, would it be enough

[millzee]

I'm thinking of trying a 4082 2200kv on 4s in a df35 pirate, could anyone with some experience with this motor let me know how it might go.
I'm thinking of swapping out my 1717 6s2p, and trying to lighten up the boat by another motor on 4s2p. Are these motor reliable??

[millzee]

Would the amp draw be a little too much running the 2200kv? I'll be using a sf240hv, should I maybe get the 1000kv and run 8s?

With the 240hv i wouldnt worry about amp draw to an extent. The 4082 is a strong motor and if you go this way you certainly do need the 2p. I thnk 8s is overkill in that boat...........its actually in the 6s zone to me personally.

The 4082 is not near the motor a 1717 is, expect lower performance at acceptible amp draw. If you prop down you may be fine, a lot depends on how freely the boat runs and how you drive it. That is a pretty big boat for 4S. Actually, running 8S in it is a great idea as long as you keep amp draw in check. Choose the prop and motor to perform like a 6S setup speedwise, not like an 8S boat. By using 8S you run cooler and longer with less stress on the components. We don't always have to pull 150 amps in our boats.

Thanks for replying, as you'll tell I'm still trying to get my head around anything other than castle motors. I'm starting to think the 4082 1250kv on 8s, that'd be 37000rpm, if I ran a x548 that I have I think it'd give me approx 108kph - 67mph or a x450 would be somehere in the 105kph -65mph. My starting goal was 100kph. I'm not sure how to work out the amp draw if I was to try this set up and these props, anyone???

can anyone please explain how to work out the amp draw?

[millzee]

Please can someone help me to hit the go button on a motor, do the 4082's have heat issues? and are the good enough for the money?

[Make-a-Wake]

I think highly of the 4082.......i have one and i'm impressed, dont get hot easily, 4 poles obviously and pretty high efficiency. I think if you want to run 8s that you go with the 1000kv...........1250 for 6s. I also think that an x548/x450 would be too much with the 1250 on 8s. If you go 1250/6s or 1000/8s i would start with an x447 and work from there.

You usually cannot predict amp draw very accurately. FECalc is probably the best method, but it is hardly foolproof and was not designed for LiPo power. So much depends on the prop size, cell quality, and how the boat is rigged and run. It would be easy to prop a 4082 to over 150 amps on any voltage, which you do not want to do.

MaW's Kv suggestions are good ones. One of my 4082s works very well in a 4S MM, the other runs hot as heck (same Kv). That means I paid double price for one good motor. They are not the quality of the Castles, and they're way behind the Neus - but then considering the price they are not bad motors. If I didn't want to save for a Castle or Neu, the Leopards are decent substitutes.

Thanks guy's that helps heaps. I appreciate it a lot, now I'll be able to get this order in without many doubt's.
Thank you both

[millzee]

sorry, 1 last question, would biting the bullet and grabbing the nue 1527 1500kv 1.5d be the best option and sticking with 6s2p?????????

[Make-a-Wake]

That would be a fast setup for sure.......but then you are back to the weight issue.........the 1527 weighs more than the 1717.

[millzee]

Done, I figure I'll have to make a few weight savings on things like that stupid metal motor mount ect. I finally hit the button on the 1527 1500kv 1.5d motor and cooling can to go in the df35 so a rebuild is on the way. I bought the 4082 2200kv to go into the MM.

[Make-a-Wake]

Nice purchase on the 1527......they rock.........what you will find impressive is the length when you see it. In common motor size terms, the Leopard you bought is a 4082 and this Neu would be a 40103..................yep 103mm long!!!
