I just got bought some balsa for the sponsons. I will hopefully make and finish them tommorow. I will for surely post pictures sometime tommorrow night.
mIke, have you started yours yet?

you better start soon. Your going to need all the time you can get to build a rigger that beats mine.[X(]

ya probably. what size motor are you using? i have a esc for a 480 size motor

I am using that graupner 480BB motor. I have all of my other electronics from my old boat. I might try to make a custom rudder but I'm not sure. I still need to buy the motor, battery, laquer and epoxy for the hull, and a flexcable and other misc. hardware. Are you for sure making one or not? IS your BBY boat running yet?

no hardware isnt in stock yet. this should tie me over till i get it. i have the money any way.

im using a 400 7.2v graupner motor and 1000mah lipo. the dimensions will be 17x10. i know its big but i will upgrade to a 480 eventually if the speed is poor. im hoping to hit 20 which it should but well see

I got the sponsons of my rigger done. I went with a really simple design that was recommended from another site. Tommorow I need to finish all of the trimming on the hull. I will get pictures tommoroow b/c my brother is gone and I'm not sure where his camera is. I still need to mount the sponsons. I will do that late tonight when I get home from fishing. When you see pictures tommorow the hull should be slmost completely done beside epoxy and sealing,ect.

What are you making your hull out of? I used pine for the main hull and balsa for the sponsons and all other stuff.

im mainly using balsa. i printed the plans out and im ready to build just need to buy the balsa now

Will dylan make one? he should so we can all race. where are you going to drive it?

I dont think he would make one. but Im not sure. I just got back from fishing from him and I was talking to him about it.

I am finishing my boat tonight and tommorrow morning. I am using wood glue to glue everything together b/c it is very strong, but I need to make sure I seal it well b/c it will come off in water. I got a bunch of tips from a few sites about building riggers. One site suggested that you mount the sponson rods on top of the sponsons. I did this. It explained why but it was really complicated. But I did it anyway b/c they said it was the best way to attach them. I also switched the sponsons that I made to more "simpler" ones. I got the idea off a 6 cell brushless SAW rigger. They are very easy to build and they are supposed to provide a lot of lift.

btw, I will drive it at the pond by my house and the fairhaven pond.

sweet. make sure you post some picsa of it whenever you get them. sounds like youve done a lot of research on it. good luck!! i hope mine turns out as good as yours. so you are using the 480 bb race. im just using the 480 race 7.2v. you will have more power than i will. my esc cant handle the draw of the bb cause it is rated 15a and the bb pull 16a and probably more on water. o well, i hope it is goin good for you.

your boat will probably weigh less than mine, though, b/c mine is made out of a lot of pine. If you make yours completely out of balsa, it should be about equal b/c of the weight difference. what plans are you following?

predator scaled down to 2/3 size

what hardware r u using. custom or what?

I am going to have to buy some nice, adjustable hardware. For riggers this is a must b/c the prop angle and rudder setup is the most important factor to how it runs. I will NEED adjustable hardware to make it run right. I am going to be doing a lot of setup on the rear end before it runs good. I have heard of people who spend hours setting up their riggers prop angle. (prop angle is the most important factor)

yup. u got it. the hardware that im using im goin to modify to make adjustable. the strut angle is adjustable just not the hieght.

r u usin fullers or sumthin?

I'm not sure what hardware I'm using yet. Ill figure that out when the time comes that I need it.
They have good Midwest balsa at sidetrax hobbies. I got 3 sheets of balsa (4 inches wide by 24 inches long rectangular pieces) for 8 bucks. I think they also have some at hobby lobby.

ya they have it there too. im ordering mine because on balsa usa they have bigger pieces there

I got pictures I just havnt had time to upload them yet. Tommorow for sure they will be up.

and balsa is cheaper. only 9.00 to do the whole boat. but shipping might get pricy tho. its light but takes up space so i guess i will find out soon.

did you order the balsa yet?

no im making a boat for a guy at the marina where we put our real boat in. hes giving me 200 to make the boat and i can keep what ever is left over. ill order it soon.

what would be better in a 21 inch rigger a 7S brushless motor or a 9L ??

im look to run 6-8 nimh 3700 cells

idk for sure because im just getting in to building and seting up riggers. but i would use the 9l if you use 7-8 cells. a 7s would be an extremely hot setup on 8-cells and hot on 7.
