Lol you putting that into the geico?!

2030 means the can is 20mm wide and 30mm long. Find a jacket that is 20mm ID but shorter in length than 30mm... I believe hobby king has them... But that's a month away:/

[Zackthrills]

Us why do you think that will nurse to much for the mg17 ? Would you post a link to a water cooling jacket that will fit it please? I looked but was unable to find anything

Just run with this...

[Gabe_k]

Should have gotten a 2045 like I told you... Right around 2500kv would be a rocket ship

[Zackthrills]

I am going to order one this one i had already ordered two weeks ago

7780kv on 2s is way to high in a boat @ over 57000rpm unloaded.

[Zackthrills]

Ok I'll just hang on to it then for another project. I have been using the minimono motor which is smaller then the 380 brushed motor it came with. What would you all recommend that i put in there. I think I'm going to use a motor like Gabe told me the 2045 what you guys think on that? Is that motor going to be small enough to fit in that boat.and the thing is is it has to be able to run on 3 s

[larryrose11]

In my limited experience with small boats, anything over 3600 KV is too much, unless you have room for 2 batteries. High KV don't produce that much torque.
Just so ya know, KV is Volts per RPM, but motor KT is Amp per Tq. As KV of a motor goes up, KT goes down. High KV motor will have low KT, and vice-versa. Its just the physics of the situation.
So, a high KV motor requires more amps to make the same torque as a lower KV motor of the same motor. High KV puts more strain on the small batteries and ESC's

[Heaving Earth]

Yup wayyyy to much kv.

[Zackthrills]

awesome that's cool to know I didn't understand that you made it to where I can understand it I really appreciate that. I still need to know what size loader should I put in that if it originally came with us 380 brushed motor that would be equal to the same size?any suggestions on what motor to go with would be greatly appreciated

[Heaving Earth]

Leopard 2860 available at ose

[Zackthrills]

Some thank you

[Heaving Earth]

sorry zack, i gave you the wrong kv for 2s. i was thinking 4s.
lets try this again
kv you want 4050kv

[Zackthrills]

K need to run on 3s pack is that ok

[Heaving Earth]

also the leopard 2845 4420kv would be great

[Heaving Earth]

so how many cells you running. 3? thats a definite answer?

[Heaving Earth]

for 3s i would go with 2860mm 2730kv or
2845 3300kv

[Heaving Earth]

heres the deal, you want your motors to run between 25,000 and 35,000 rpm. i like mine to be 30,000 to 36000 personally. right in the middle is great at 33,000 or so.
to calculate just multiply motor kv x cell voltage
ex. 11.1 (3s) x 2730kv = 30,303 rpm

[Heaving Earth]

i think you need to slow down and understand what your doing instead of just impulsively buying stuff and changing your mind every minute. jmo

[BHChieftain]

+1.

I like the 28-32K range myself. The higher the RPM the more you need to worry about vibration and wear in the drivetrain.

And no I'm not trying to be mean here. Just trying to save you aggravation and money

[Zackthrills]

no I completely understand and agree with you earth. I happen to buy that motor for the recommendation of a local guy at the hobby shop which I should have got on the forms first but I was unaware of this for me to recently. So what I had figured is since I already bought the motor and I got it for such a good deal is that I would go ahead and run it until I got the motor that you guys recommend would be the best for it and if it burns up then it burns up. As last night I was testing out my MG 17 and I think I burned the motor up again.I really don't understand why it would have burned the motor up as I'm running the exact same setup that is in the mini mono motor ESC batteries everything.

[Zackthrills]

I really do appreciate all the advice and I'm going to look at buying one of the motos you recommended and trying to keep the RPM range as you we discussed. To me this is just a project and a lining experience that to be honest is relatively cheap for me. I have always had hobbies setup cost me a lot of money and to be honest with you this one is one of the cheaper hobbies that I have had. Show for me to burn a boat motor or two like I have done at 2030 dollars a motor is really not breaking the bank. But I do understand what you mean and there's no need to waste money when I can get it running properly which that's why I've come to you for the answers. I respect you guys that I've been doing this for a long time greatly and look for advice from you and the wisdom that you have gained over the years and look to further my knowledge

[osprey21]

Where in Fla. are you?

[Zackthrills]

Tampa hillsbrough county.you?

[osprey21]

Bradenton (Manatee Co) You should come down on one of our TnT days to ask questions and see many different boats/set-ups in action.

Just sayin' :tiphat:

[Zackthrills]

I definitely will that sounds great

[Basstronics]

I have a 20 sized water jacket available $7 shipped.

Same one shown here:

**Edit**
Mine has the water inlets/outlet at 90 degree instead of 180 as shown. Overall length is right at 30mm.

[Zackthrills]

I'll take it pm me pp I'll send to zackthrills@yahoo.com thanks Bass
