sss vs leopard motors

[tjsb]

looks like the SSS have higher output? are they better?

[koen]

the SSS motor is a good motor , if you see the spec SSS has more power

[tjsb]

sss better than tp of the same size?

[koen]

what i found out a TP is a better motor but it is close ,but a TP is more rpm stable

[Bande1]

TP is overrating the figures a bit. Think of them as speed run figures not long oval lapping figures. reduce them by 20% for that. same probably applies to SSS. its kinda a marketing gimmick. TP seems a bit cheaper than SSS so I run TP. I like the look, kv options, and can size a bit more so thats what I buy.

TPs are the better motor. They are the best China motor that I have worked on. And a Tenshock is a good second. These two are better , in my opinion, simply because they use the better higher temperature wire for the windings (200*C vs 155*C). I would rate Leopards a notch above the SSS line, but not by a large margin. I base my statements on what I have seen by running all of these different motors and taking apart a couple thousand of them.

TPs watt rating gives you a peak "BURST" rating and a lower continuous rating. And I have exceeded both several times. I have some 3660 motors that have pulled 4500 watts repeatedly, but only for a few seconds at a time.

It's hard to compare motors going solely by the specs, because there is no standard way for the manufactures to describe their motors. A 4060 TP has a 40mm diameter and 92mm long can, the 60 is the length of the rotor! A 4092 SSS and Leopard, describes the can size only, and you have no idea of how long the guts are. A tenshoch 2240 motor describes the diameter and length of the rotor, and tells you nothing about the can. Weight is another way to compare, but again some of them are gonna lie about this too and include the connectors and the box it come in as part of the weight.

Looking at the spec and weight of the 4092 motors you would think the sss is better than tp or leopard?

[koen]

no a TP 4060 out perform a SSS4092 but it will pull more amps, and weight wise the are about the same

the difference between TP's 4060 3kw rating and an SSS or Leopards ~2600w can be slightly more wet hull or rough water. 400w is a tiny difference. My TP 4070 runs 140f at 3kw after 60 seconds. its rated for 3850w. so running either of those near their claimed limit for a long period gets them quite warm. Running 6s at 3kw is going to start melting solder joints and requires 8awg. Its also more than cheap lipos can really put out before they drop below 3.2v. SMC's can do it but amazon specials struggle.

besides speed runs if you plan to get your boat beyond about 2,500w on 6s continuously you should move to higher voltage and a next size larger motor (and lower KV) anyway. its marginally more cost and your parts will run so much cooler. There's no sense trying to play in the margins for tiny performance differences.

for example pulling 3kw on 6s will be a real world 150A
going to 8s with a KV to match your 6s RPM will pull about 110A. Much more realistic for most batteries.
Go bigger - 4070 1090kv 8s

The IMPBA events have always been a breeding ground for cutting-edge advancements in boat design, and this year will likely be no exception. Spectators can look forward to seeing the latest innovations in hull design, engine technology, and aerodynamics.

I'll admit I'm not knowledgeable enough to answer the question you originally asked, or your follow-up question...but, having been a member of this forum for a while, and having read the posts from many long-term members, I can tell you this:

Of all the comments in this thread, I'd trust what donhuff says more than what any others said. Not trying to put any other comments 'down'...but, of those who've commented so far, I'd estimate he is probably the most knowledgeable.

had a 30 year boat veteran put a 2315 3 blade prop on a 1390kv leopard on 8s because it was what worked on his boat. Had another swear that bending the tips of a prop causes it to throw a tighter thrust cone and thus lifts the transom higher. Another swore that when you go up in battery voltage you have to go up in prop size because higher voltage = more torque. And still another veteran argued on the phone at the lake with castle creations tech support for 45 minutes that LVC should never be more than 3.0v or you are "wasting your battery."

I highly doubt the battery voltage/prop size thing you mention...you had to have either misunderstood, is you got that from someone else who misunderstood. Same goes for your final point...what you state there doesn't make any sense, even to someone with almost no knowledge. As for your first point, all I can say is, if that's what worked for him, them that's what worked for him...and, since you provided no info on the boat, itself, it IS possible.

As for motors brands, having spoken with numerous others, I personally know MANY of them have tested different motors, and can confirm that, of the three (SSS, Leopard, & TP), TP has consistently proven to be the best in "real world" use (ie. not 'specs', which can be fill of lies, thus completely meaningless)...especially the upper-tier motors. The reason most tend to go with SSS & Leopard is that, for the most part, they cost less. From my own personal experience, both brands are still very good (SSS is actually made by TFL)...I trust both in my recreational boats, and have used both in one of my three race boats (that boat is currently running an SSS). I will mention that, in that particular boat, I didn't like the Leopard, which is why I returned it back to SSS.

Regarding 'specs', for the most part, ALL companies lie to some degree. It doesn't matter if you're taking motors, ESCs, batteries, servos, etc...the numbers they publish are NEVER 100% 'truth'. As someone already mentioned, published numbers tend to be a "marketing gimmick". Additionally, 'numbers' published tend to be from testing done under "perfectly ideal" considering, not "real world" conditions...in the "real world", nothing is ever "perfectly ideal". Plus, since no two units are completely identical, you could test 10 of the exact same motor, servo, etc, and get up to 10 different results.

We live in an imperfect world...so, you should expect everything in life to be 'imperfect'.
