1717vs4082vs1520 which has the most to offer

[crrcboatz]

I know what hull, lipos, props, etc. What I am looking for is the best application for each. Also just how much raw power difference is there in the 1520 and the 4082 cause the 1717 wins if the 3 are compared.

So if u have used any 2 or possibly all 3 tell me what u know.

Just my experience. Tried a 4082-2200 in my p-mono. It died a crunchy/smokey/smelly death. Put a 2200kV 1515/1y CC/neu in it and have no problems at all. It pulls the prop that killed the 4082 and doesn't break a sweat.

If you're going 6S, the 1717 is hard to beat. The 1520 is a good option if you are space limited.

Don't shoot the messenger.

So what was the size of the prop that sent the 4082 up in smoke

I also am very curious to what relationship "watts" have here. A 4082 is rated at 3.5 watts? A 1515 2.5w? Now I agree the Nue is more efficient than the Leopard. Does that add up to it making more power and pulling more prop. I am not questioning this just looking for the logical explanation. I have a 4082 2200KV and if the 2200 1515 is better it surely is worth it to me as it's lighter and a better fit on an outboard setup. Specs and size on the 4082 make more of a match to the 1521 Nue. If the 1515 will outperform the 4082 it is definately worth the extra money.

can we stay on subject here guys. I am not interested in prop size, watts relationship, etc just experience from those who have used these.: please

I have a DF 33 that had a castle 1520 and now has a 4082 1600kv. Both motors run excellent and can turn the same props with ease. It seems the Leopard will run about 2mph faster than the castle. Both run cool and have no issues. Comparing these two motors to a 1717, I'll always take the 1520 and 4082 over the 17 series. They both run faster and seem to put out more rpm given the kv difference. 1717 stays cool and runs decent but I have no use for it. The 1717 definitely does not win. It's not a bad motor by any means, I just prefer the other two over it.

Terrific info and tnks very much. Spot on stuff So if I understand u correctly u think the 1717 is not quite the motor in u r applications mentioned.

I have 4-6 boats right now I am lining up hardware, motors, and escs for to be fall/ winter builds. I have 2 each of the 1717s, 1520s, and 1518s so the kind of info u have layed down is great help.

I am trying to trade for a 53" cat right now and had thought I'd put the 2 1717s in it, now maybe not. When and if I ever get my hands on the esc I am waiting on I will have everything for my first build using a MHZ cat hull and a Scorpion 4035 outrunner.

The 1717 is an amazing motor, but it needs to be pushed hard to come alive. It's a great heavy boat/big prop motor.

As far as the cooked 4082-2200 the prop was a pitched up M445. Same prop on the 1515 doesn't make much heat at all, under 100F after 8 laps (mill+1 mile+cool down). The problem with stated wattage ratings is you have to trust the MFG the rate the motors accurately. The Neu's and CC/Neu's seem to be rated conservatively. My one experience with the Leopard was it didn't live up to the rating. This is also only one test with one motor, it may have been a defect from the factory.

I doubt it. Its been reported by several OSE members that the Leopard 4082/2200 kv motor is well known to have heat issues. Just do a search here. You will find the posts. I wanted to try one in a rigger and after reading the heat issues decided its not a motor I want to try. I like the 1717 myself. With a bigger diameter rotor then any of the 15xx series its got much better torque in a comparable kv can. More like a Neu 1524 then a 1521. But you already know that.

Thanks Brian
Why i asked about the prop is i had the 4074 2200 then went too the 4082 2200leopard on my outboard tunnel i also use a stock m445 and can make 1 mill 5 lap race and 1 mill finish lap but end up with 10% left out 0f 5000 45/90 discharge batterys. would like a bit more left in batterys .

Motors get hot when run out of their efficient range. It's this simple, if your motor is getting hot your load is to high. I run the 4082 2200 in my p mono on a x445 and it screams. I ran the same motor in the offshore class for 4 minutes.

That's why I wondered if it might have been defective from the factory. It should have been a perfect P-mono motor.

F1,
If you have a prop you like but want a bit more run time, shave the diameter down 1-2mm. It doesn't take much to get big gains in run time.

The 39" mono in my signature is pushed by a 1717 and it hit 59mph............... Running a T180 with 2 additional 1000uf caps

I jut hadto chime in cause I did see you also put a 1518 in there. I have 2 of those and love them also havea 1717 buthavent hd the chance to get on it yet. In my mg I hit 62.1 with a 1518 my buddy had a 1520 and 4082 1500kv in his spartan and riht now the 4082 is barely out performing the 1520
