Default Micro rigger (12 inches)

Hey im making a micro rigger for fun. doesnt have to haul, just cheap fun.
here is what im planing on using
[link=https://www.unitedhobbies.com/UNITEDHOBBIES/store/uh_viewItem.asp?idProduct=5379]Motor(micro outrunner)[/link]
[link=https://www.unitedhobbies.com/UNITEDHOBBIES/store/uh_viewItem.asp?idProduct=2054]LiPo Battery[/link]
[link=https://www.unitedhobbies.com/UNITEDHOBBIES/store/uh_viewItem.asp?idProduct=4317]Esc[/link]
Im making a .032 wire drive for it. im open to any suggestions...

BTW, the only reason im using an outrunner it because i cant find small enough props that will work with an inrunner, if you guys know where i can get really small props ill use an inrunner

here are some pics of it so far...

if you want t heat epoxy, use a hair dryer. if you want to thin epoxy, use epoxy thinners. heat helps it set, it will make it runny for a brief period, thinners helps to get a nice smooth coat.

To thin epoxy, use some denatured alcohol. You can put in on then wipe the excess off with paper towels. Yes, the paper towel trick works but do it right after you lay on the epoxy.
Try www.microhydros.com for more ideas if you already haven't. It's a great site for info on small boats.

cool rigger. I hope it works. I dont think I will have a rigger running for a while just b/c I dont have the money for the hardware. Its all so damn expensive. If I do get money for hardware, I will remake my rigger out of all balsa, b/c mine is too heavy. I will probably also make it smaller kind of like yours. good luck

Even if you do have the money, you can still make your own and save probably $60. Plus, it's fun and rewarding.

OSE has the most reasonably priced micro hardware I've seen yet. http://www.offshoreelectrics.com/pro...mcr-mhd&cat=69 If you made your own you'd still probably save around $40.

hi,
looks great, your really moving on the build it looks like. i built a few scratch riggers too and tried outrunner motors, they tend to get hot, i found a pretty good cure for my last rigger. when you make your motor mount use "L" angled alum (from like home depot or so) cut it the full width of the hull so you can epoxy it to the sides, have one side hold the motor and the other side go right through the bottom of the boat so that it is exposed to the water but epoxied flat out side of the hull. water will cool the exposed part and transfer heat from the base of the outrunner. you can see the exposed part in a couple of the pics that show the bottom of the hull.

to see the pics, look at post number 40 and 41 here http://www.rcuniverse.com/forum/m_60..._3/key_/tm.htm

building can be fun,
john

i just looked at your equipment list, im just guessing here, but i think the 10amp speed controller will not hold up very long in your boat. maybe find one in the 20 amp range, boats are hard on esc's. my suggestion to stay within a low budget would be a thunderbird 18 controller for that motor. you can get them for $25.
once again, the boat looks really cute so far, it should be fun finding out how it runs.

im still debating on whether or not to use rear sponsons. what do you guys think? someone said that you can use a bigger prop if you use them so i might.

i would need to see a side profile picture of your hull to give my opinion on the sponsons, its hard to tell from what i can see from the other pics, i think you will need sponsons though to get enough hull out away from the waterline. i need to see the angle of the tub and front pads to see if it looks like it will plane or not.
