would a leopard 3674 2200kv be a good choice for my revolt with a seaking 120 v2 on 4s:confused2: please give your opinion cause i have to buy a motor mine smoked:flashfire:

How did you burn up your stock motor? Didn't you just get your boat?

yes i did just get it i dont know what happened 3rd run on the boat im uploading a video of it will post it when its done it never quit running just lost power so i brought it in and pulled the hatch and well you will see in a few and the temps were only about 145 on the motor im still stumped :confused2:

Either the 1900kv which allows a bit bigger prop(m445 etc............) or the 2200 will be fine. The 2200 needs something in the x440-x442 range............................JMO.:Peace_Sign:

What prop were you running?

when u say bigger are you meaning diameter or pitch thank you make-a-wake for you thoughts im running the 45x68 grim prop

Thats a huge prop dude!!

Definitely! It'll pull it, but only for 2-minutes or so.

Seems like a lot the emphasis on hitting those magic top speeds on the GPS sure seem to burn down a lot of equipment.

Couple of questions and observations...

* Is your 45X68 balanced and sharpen or did you put it on right out of the box?
* I noticed that you have an after market speed-o. Do you know what timing the controller is set to?
* The boat was still running when you brought it in, does the motor still work? (oh, I just noticed you said it lost power).
* What kind of battery are you using
* What size of connectors are you using on the motor and controller?

It hard to tell in the vid, but the boat didn't "look" to tight to the water. However, 145 is to hot in my opinion and you did run for close to 3 min. If the props stock (NOT balanced and sharpened) it COULD be part of your problem.

prop is balanced and sharpened timing is set to 7.50 battery is 5000mah 40c motor has stock 4mm connectors and is that not what aquacraft recommends ??? do i need a different prop

When you recharge your battery pack, how many mAh's are you putting back into the pack? The reason I ask is the voltage drop across your run.

Have you ran the boat again with charged batteries?

MAMBA2200
10-05-2012, 11:27 AM
in that set about 2400

Hi guys
I think the 5000mAh 40c are heavy, not less of 600g if you add a big GPS and a big prop to spin for a lot of time, stock cooling circuit is not enough.
Don't forget that more it is heavy more the ampere are on demand, and more ampere is more heat developed.
If i can give a suggest replace stock motor, it is strong and light,with and a front bearing cooler and add heat compound,the same of CPU beetween motor and motormount and beetween motormount and bearing cooler, first ESC cooling than bearing cooler and than motor
I still haven't any heat problem and i've already try the 45/68 but not with gps,all motor setup is EVER barely warm.
sorry for your dead motor my friend.

Grimracer
10-05-2012, 11:51 AM
Yep.. bad idea.. path of least resistance.. ya know.

3rd run and you have made that many changes? Can I ask why?

Truth is none of my "4S E stuff" seems to get over 115deg..(eagle tree sensors logged durring the run)

Grim

MAMBA2200
10-05-2012, 12:05 PM
i did all the changes before i ever put it in the water but i will change it back thanks for the info the esc change is just for adjustability of the lvc

The prop is simply too much, if you want a reliable setup that will be as fast as it was in the vid go for the 1900kv with an m445........................all the batt and cooling stuff is irrelevant, you have way too much prop.

Grimracer
10-05-2012, 12:18 PM
Make a wake has the concluding word..

RELIABLE!

the prop you have on now is MY FAVORITE prop BUT... I race my boats..I do not sport run them.

The prop you have now is FASSSST.. but.. again. Darin said it best.. Limit your run time.

So much to learn.. Your alright.. stick with it. We are all learning as we go.

I found issues with the stock motor bullets... both my revolt and my ul1, under a heavy load they simply FALL OFF. I suggest checking this as the motor will seem to not work; drop on some nice 5.5mm or so bullets with your own solder and golden.

i have 5.5 conns coming also for everything in the boat the motor never quit it just really slowed down but i thing it will work well in my recovery boat im building after it cooled down seemed to be fine gonna test it in my pool before i have to recover my recovery boat lol:hornets_nest:

Mine did not fall off or even feel loose, BUT, they were leaned up against the plastic battery tray and melted a hole in it! So obviously there is some high resistance in these smaller connectors? The only mod I have is a 45x68 prop, could this be why they are getting hot, if so what should I beef up? Is there any issue with soldering the small wires to the large 5.5 connectors? Some of these 5.5's state they are for a specific wire size, such as 10awg or 12awg.

Hi Tom,

I installed 5.5's on mine before it hit the water not on the motor side just the battery side of the ESC.

Well i replaced all connectors on mine took the water line spliter out and ordered two 4s packs 5000mah 40 c and shortened all the wires on eagle tree and esc hope this will help some

Hi Mike, I did the same, except used EC5's. I'm thinking about changing the motor/ESC connectors but just may wait until I swap out the stock ESC with a 180, it has larger wires to work with.

If the wires are smaller as some esc's are you can when soldering make sure to have good contact in the base of the bullet, maybe even strip extra and bend it up so it's double thick. With the hobbyking bullets they have part of the top cut away anyway which is nice, I just make sure to have my wires have contact down the full side and in the base.

Hi Tom,

Please let me know how the 180 works for you? I just bought three new props M545, M645 and X642. Need to play some more as I have not been out. And I am re powering an old mono that ran 40's in 1972 with the Revolt system to see how it will run.

Hi Mike,

Yes, certainly will let you know. And please let us know how your props and old mono work out? The 180 ESC upgrade probably won't be this season. Here in Michigan the cold and winds are starting to roll in so there is not much enjoyable warm weather left, especially since I'm working and can only run in the evenings. I did order a M545 prop yesterday that I will sharpen/balance and compare to my 45x68 this coming week. I have found that I enjoy this hobby and really like the Revolt 30. So this winter I plan on picking up some parts to fool around with. I like the current hardware it came with but now have the urge to experiment. I think the hull is very capable of 50mph, which isn't that much faster than some are already seeing. I don't want to overtax the current ESC, motor, wires or batteries. I need to learn more on what is the best route to achieve consistent 50mph runs. I have all winter to read and think about it. And I'm sure by then others will have already achieved it and beyond!

Cold in Chicago too, to soon to cold. I was going up to Flint for time trials but Family needed my help that's always first. I will PM my e-mail address talk later anytime.

See Prop Diagram

I took a picture of a new Octura prop sheet 9.12 for everyone to use!

I notice that you have larger exit tubing from the motor.....................if thats not an illusion from the photo. I have thought of a theory about that. It would seem that the larger tube would allow easier exit of the water...........ya know, freer flow and should increase efficiency in the cooling system. Sorta like a car exhaust system that increases in diameter out near the rear to allow better flow..........

Also, that 1900kv may be able to handle an x642.............or x447, just a thought, maybe others will chime in about that.

not an illusion i just put that 4 mm on cause i could not find my 3mm in my mess at the time i also got a m445 with the motor couple of the guys here said that would be a great prop with this motor:beerchug:

Yep, i was one of the "guys"..................I'm just thinking that if you wanted the extra 4-5 mph that the 1900kv versions may be able to swing the props with higher total pitch. The m445 and that motor will be a very reliable setup that will run cool and last..................oh, and good speed!

i hope it will be that was the roughest prop ive ever seen it forever to b&s that prop hope it works well which you say it will so im good with that info at this point i hope it busts 40mph lol
