Who's Running a Micro? => Less than 16"

[Meniscus]

Very cool damfurst. What props are you running? If you don't know, at least measure the diameter so that others can benefit of knowing what setup works for you. Any pictures?

Thanks.

Not wise but doable.
I have a 22" tub rigger that has a 7S-5070kv can that I once fed with 3S to the 432 prop for low to mid 40krpm at the prop

What is being suggested above is good for low 50krpm at the prop and there is no surprise that he blows carbons at those rpm. I blow them at 40odd krpm. Given they are suggested for up to 25krpm then we are all having fun.

Some guys use high rpm for speed and some go for prop dia. I like rpm. It sounds nice.

If the you-tube vid will ever load then I may get to see his boat doing its thing, for now I believe him.

I was just trying to say it sure does'nt sound like 50-60 thousand r's in that video

This is what a 60,000 rpm set up in a micro sounds like.

Bad link, "http://http" should be just one.

I need something that can fit my 2s 3600mah lipo and turnigy built in watercooled 3600kv. Would prefer a hydro or cat. I had 2 hulls before and was not satisfied with the severly warped hatch and the one I just got in the mail is too small and can't fit them in.

what is the physical size of the 3600mah battery? You may be asking for a lot to find a boat to carry that and still perform!

Can you provide dimensions of the lipo, motor and the ESC you're planning on using?

Here is the motor and battery. 60amp Turnigy

It looks like you have some good components to get you started. The motor mount you are referring to is sold here on OSE: http://www.offshoreelectrics.com/pro...prod=ose-80100

If you take into consideration that:

• your lipo measures roughly 5.5"
• your ESC measures roughly 2"
• your motor measures roughly 3"

Then you're talking about a model that has to have 10.5" worth of space up to 13-14" when you consider the receiver, stuffing tube, etc., without having to cram components in. This means that you'd probably be in the 17-18" model range in order to fit this configuration and allow for COG (Center of Gravity) adjustments.

My concern is, with your lipo being 2s or have a nominal voltage of 7.4V and the motor being 3600 KV, you are looking at 26,640 RPMs before considering loss due to driveline, slip, etc. Many of us are running RPMs more in the 33k to 36k range for sport boating.

You have a few options when you add all of this up. With the lower RPM, you could run a larger prop to make up the difference. Of course this will result in a larger amp draw which shouldn't be an issue for the lipo, but could be for the motor and the ESC.

Another option you have is you could pickup a 3s lipo at 11.1V. This would result in a high RPM, but would allow for smaller prop and result in less torque roll.

Regarding a hull for this exact setup, a good option might be a mini Sea Drifter at just under 18". You can see a picture here. This one is mine, but I might entertain letting it go. I don't know what your budget is and I don't remember seeing your goals for this build. This specific model is a little taller and your lipo may fit sitting sideways in the front.

Anyway, just a few ideas if you are intent on using the equipment you already have. Here's a link to one of these new, along with a video.

I hope this helps.

On the Gecko I have ran Graupner 4mm 30mmD 2 & 3 blade. Right now it has a 29mm 2 blade. Here is a couple of vids of it one with the brushless & one of the 480 brushed on the creek

The Micro Hydro has had a 32mm, with a 27mm currently with the 3800kv.

Here is the only vid of it in stock setup.http://rcuvideos.com/video/Micro-Hyd...nShock-Mini-Ca

Hay fellas this may not qualify but i have a 17'' pickle fork hydro i got used, im trying to put back together, hull is plastic has a 4200 or 4800kv motor not sure wich one,will be using a 30amp esc i think and it came with a plastic prop and two octura x427 props. gotta put everything back together, hulls in two halfs. O will run on a 3s lipo, i think,,,

I now have a micro rigger ...

[HYDROJERRY]

I now have a micro rigger ...

aahhh looks cool, where did you get it,how much, how does it run,any pics of the inside lets see please....

LMAO!!!

I was just admiring this pic in your avatar in another thread. Then I find it here! There's something suspicious about those numbers on top

Hilarious and caught me off guard. So, I can I buy one of these micros at the street vendor over by the Loch?

[Meniscus]

OK, I'm bringing this thread back up.

Share what you have in micro size or close to it!
