Default My Kyosho Sunstorm 600 Brushless Experiments

Ok, I picked this Sunstorm up pretty cheap, $50.00 shipped. I have just dropped a Feigao 5498409L brushless motor in and have hooked up the water cooling. I am in the process of picking up a Brushless ESC for it. If anyone knows of any good deals on a brushless ESC, about a 80amp should do, let me know. I will try it on 6 and 7 cells first. If I don't get the results I am looking for, I will have to cut out the entire rear inner hull and remount the servo so I can drop in 12 cells or so. I can't wait to get her in the water and see what a Brushless motor will do for a Sunstorm. Next I will be trying this in my Aquajet, to see what happens.

Sounds like a plan! I am sure that it'll boogie!
About the ESC, I pesonally like the Barracuda 80 (there is a 125 version),
they have an option to install a cooler for about $20... I believe you can
find that ESC for 140ish at most places.

That is neat.
I had a small fast boat that would skip across the water,I think yours will do the same.
If you are able/willing please post a video.

Thanks

thats sweet
you can impress your freinds saying its just a stock boat ! lol and ppl will look at it like it should be at the bottom of the lake , and then zooooom lol
can the motor handel 12 cells ? i thought it was only good to 10 ?
oh but you have water cooling so you should be good !
and rember to change out the prop !

Thanks for the suggestion, but I am not interested in running LiPo's in boats right now.

I emailed Jamie at Starluckrc today about the number of cells/volts the motor can handle and here is a quote from his reply email.

"It is mainly a 12-14 cell motor. Some have ran up to 16 cells, but that is
a little beyond spec. You have to be very careful
with heat at the higher voltages. Best rule of thumb is too keep it around
30-40k rpms".

So I guess 12 cells is safe. But just for the sake of not ripping out half of the upper hull where the radio box and servo mount is, just yet, I will try 7 cells first, and if I am not happy with the results then I will begin to modify the upper hull.

nice, but I dont think I'd try 7 cells, if they say 12-14 thats what you should use. maybe you went overkill. If you cant fit them in the boat, is there a chance you could use AA's or lipo's. you might need to. The setup looks and sounds sick tho.

Default RE: My Kyosho Sunstorm 600 Brushless Experiments

Thanks quicksiler, Using less batteries won't hurt, so just for kicks I will try 7 cells first just to see how it goes. I would hate to think that it could work out great and I didn't even try it. If that doesn't produce some speed, I will then modify the upper hull and then 12 cells will fit very easily. I have studied the area that needs to be modified and it will be very easy and I won't even have to mess with the way the hatch mounts at all. AA's do not have the capibility of supplying the amp draw needed for this set up, Or for any fast electric for that matter. As for LiPo's, as I said above, I am not interested in LiPo's for this project. I have them in some micro cars, but I don't want to spend the money for a LiPo that can handle the amp draw of a large boat application right now.

Sorry if this is a down but 30k is out of the question for that hull motor and drive system

if using the stock prop stick to 6 cells - you will geta good turn of speed
if you get an eco prop then you can put more cells - however the hull is only designed for modest speed so if you want 35mph grab yourself a small race boat.

35mph?? I didn't say anything about 35mph. I have a small race boat that is somewhere in the high 30s, its my Gecko running a Feigao 400 brushless on 10 2/3A batteries. I am experimenting with this boat becasue I picked it up cheap. Just wanted to see what would happen and of course I will be experimenting with different props.
PS What is 30k? are you talking about 30kph? If so then please say it that way. And if you were talking about 30kph, then thats only 18mph and that is not unrealistic. I am looking for mid to high 20s. I'll keep you updated as soon as I get the ESC.

mahogany dreams, I was out of town for a couple of days and I still haven't ordered the ESC yet. I really haven't decided which one I am going to get. I think I am going to get the Baraccuda 70. I should be able to make up my mind by tommorow and order it. I should have it installed and tested by next weekend.

GRK you should put that gecko in the SAW's (google it) its a record setter.

The 30k refers to rpm; 30,000 rpm - the other thing i mentioned was a prop - any thoughts on what you might use there?

good luck with your project - lookign forward tot he video

Well, I googled SAW's and way too much info popped up, do you have a link?
I don't know what size drive dog it is, but I do know that my Aquajet Extreme has a larger one but the same size shaft, so I may pull the shaft out of my Aquajet and put it in for test.
Any help with the drive dog size and props would be appreciated.

Look up SAW legge Lake NAMBA - that will get if for you

the motor makes 2371 rpm/v - its good for 7 cells but the efficiency is poor - especially up to 45 amps - it needs water coolign and you may find it runs cooler over 45 amps than under it. It isnt a long run time motor but it wil be quick.

The prop you need is an eco prop. You can get them from Hydro and Marine in Germany get a 29 3blader and a 31mm 2 balder - these props are very very good for submerged drive - you can modify octuras and stuff and they will be ok but these little things are like scythes. They make for great performance - importantly they let the boat settle in the water and rund ecently - a modified surfacing prop wont - unfortunely the motor is doing too many revs for any of the scale props in USA - make sure you get the props sharpened and balanced. And the earlier advice ont he barracuda 80- is good IMO this motor can suck amps and make heat

I am now considering modifying it to a surface drive. That would keep me from having to order props from Germany and I would also be able to borrow my prop from my Aquajet extreme. Doesn't look like too hard of a job. But I will need some new hardware, like a longer rudder mount and a servo mount. Offshore has a nice JR servo mount thats pretty cheap, I will probably pick up one of those.

Here is the before and after pics of the first step that is now completed. I cut out part of the upper deck to gain access to the bottom of the hull for new set-up and more batteries. I was already dremeling when I remembered before and after pics would be nice, so thats why you see some dremeling already done in the first pic.
Next steps to complete the project will be as follows.
1. Seal original shaft exit hole.
2. Make new hole for surface drive set up and install stuffing tube.
3. Move motor mount.
4. Install new rudder.
5. Install servo mount and servo.
6. Mount motor
7. Install ESC and Reciever.
8. Charge batteries and head to the lake.
Let me know if I left out anything. That might not be the exact order in which I will complete each step.

Default RE: My Kyosho Sunstorm 600 Brushless Experiments

try this

what you have done is good for sub surface too - it lightens the hull and you can reo the running surfaces so the are stiff

use t pieces of very light ply or balsa strips - glue with ca

this is a short fat hull and surface drive isnt what it will like -- it willbe fast but will flip roll and end up full of water. its built around subsurface and will make a passable boat if you keep it that way.

keep the submerged drive and use an Octura X430

this will keep the boat upright more often than not - you will loose some top speed and runtime but the thing will corner in a manneer which will blow you away - a surface drive version of this hull will be a dogs breakfast - it wont be stable in a straighline in will be slow.

BTW I have the eco props if you need them.

My advice is dont try and over do this hull you will end up with something you will throw away out of frustration.

Thanks for the advice, but I wish you would have come around before I drilled the hole in the rear of the boat. but thats ok, I can easily seal it up. That would be great if you could send me an eco prop. Just let me know what you want from me. I am ordering the esc tommorow, so I am eager to get her finished.
