SSS 3660 1620kv

[Ejay]

This motor comes in the HK Pursuit, does anyone know the specs on it or what prop and batteries work best. I have done some searches but have not found much. I noticed they sell the SSS motors here but not this particular one.
Thanks

I would also like to know more about this motor if anyone has found more information on it.
I believe it is a 4-pole motor but don't know the wind type.

I would like to know in particular what the ESC timing should be set to from those who have had some experience with running this stock Pursuit motor.

I can't seem to find any definitive info on the timing used for this motor on any of the forums.

Thanks,
Dave

It's made by or for TFL. Here is a link. http://www.tfl-hobby.de/product_info...4d3fa91f999927

Surprised that it's a D wind. I have a Princess (sorry it's a Pursuit) with this stock motor for sport running (not racing). I run it with a Swordfish 120 data logging ESC, set on auto timing, with 4 cell pack. Favorite prop is Octura M445, 39MPH at 65amps. Other prop is Octura M545, 42MPH at 76amps. Never did try the stock prop. I think the stock Pursuit is a great buy, and it also responds well to upgrades.

Thanks for the informative link and prop recommendations zooma
I will start with 0° - 5° timing and check temps.

This is my second Pursuit and I'm looking forward to running it with the stock motor but upgrade the prop and drive shaft for some more relaxing sport running and hopefully better run time.

My first Pursuit I outfitted with a Leopard 4074, Seaking 180 and a one piece drive shaft and it goes like stink but flattens my 4s 5000 mah battery in under 3 minutes.

Capt'n,

I just edited my previous post to say that this boat is a Pursuit (not a Princess). This is my go-to boat for sport running, thus saving my race boats. My race Pursuit has a TP Power 4072 2200kv with seaking 180 on 4S, with an M445, and is a lot faster.

Zooma, what kind of run time do you get with your setup?

[Capt'n Crash]

I finally got my sport Pursuit up and running with the stock SSS motor, M445, Seaking 180, one piece flex and 4s 5000 mah Thunder Power battery.

I was very pleased with the results. Descent speed of about 40 MPH with a nice rooster out the back.

It's not quite as fast as my race Pursuit with the Leo 4074 but handles great and is very relaxing to drive at full throttle with turns like it's on rails.

As far as run time goes I still only get about 3 minutes which leaves me with 38% left on the battery and all the components are just warm to the touch. Timing was set at 3.75 degrees.

I guess I will just have to bite the bullet and get some larger capacity batteries for both boats if I want to get to the 4 minute run time mark.

two 4S 5000's in parallel should work. Probably lay them next to the motor to get the proper center of gravity.

[Capt'n Crash]

Zooma, do you think the boat can handle that much additional weight?

Also I would have to reconfigure the esc wiring as it's set up for two 2x2s 5000's in series.

Was wondering if 2x2s 6800's might get me where I want to go.

That weight is no problem for the Pursuit. My P class has 4S2P 5000's. I did have to get the parallel 5.5mm bullets, I think from OSE. If you went that way, it would double your capacity and probably run time, but you should put a couple of battery trays along side of the motor, so you can maintain the proper center of gravity. If you go with the 2x2P 6800 packs, it is only a 36% increase in capacity, but a simpler change. Try to keep them as far back as possible on the stock battery tray.

Sorry that I did not answer your question about run time last year. The truth is that I have never timed a run. It's just the number of times around the lake or race course. But speed runs up the current draw and runs down the battery. I would think that 3 minutes is about right for race speeds and 4 minutes at sport speeds.

[Capt'n Crash]

Thanks for the advice zooma and now that I've looked around I see a lot of people are using two 4s packs in their Pursuits.

I have both boats configured such that the batteries are mounted on either side of the motor so no problem getting the proper COG. The only thing that's mounted to the stock battery tray is the Seaking 180.
I use the castle 6.5 mm bullets with the green casing so I'll just wait until the season is over to reconfigure the esc wiring for the new 4s batteries.

I can always use the 2s 5000's in my revolt 30's so they will be put to good use but for now I'm content with a 3 minute run time with the Pursuits.

I also bought two of those premium sharpened, balanced and thinned M445's from OSE, one for each boat and now the racing Pursuit with the Leo 4074 is just stupid fast. Makes me nervous I'm going to break something every time I run it

[airbiscuit]

So running two 4s in parallel will give more speed that one 4s on the pursuit?

[zooma]

Good plan. Hey, I have never seen those sharpened M445's in stock. Thanks for the heads-up, just purchased 2.

[Capt'n Crash]

Zooma, you will love those premium M445's, the workmanship that is put into them is truly a thing of beauty.

Airbisquit, I don't think you will get more speed running two 4s in parallel but longer run time if the capacity is greater than a single 4s as the output voltage will be the same in both cases.

[Fluid]

Actually running 2P will give slightly higher power since the amp draw per pack is cut in half, allowing each pack to supply higher voltage. The higher the amp draw the bigger the advantage. But, the weight is higher so what you gain in power may be lost in more wetted surface. As with most things, it depends.
