Mini Rigger

[Basstronics]

Ive been wanting to do a rigger for awhile now. Just not familiar with them and whats good.

After the reading I have done I would like to build a scaled down version of the JAE.

I have downloaded the DXF and scalled it down by .6666"

This is giving me:

20" overall tip of sponson end of tub
12 11/16" sponson to sponson
2" wide x 18 13/16" x 1 3/8" tub
Sponsons 7/8" wide

Im thinking this might be a good start point.

Power would be:

or

Think this is going in the right direction?

If anyone has hull ideas/plans, etc I have CAD (AutoCAD). I also have 3D CAD and I can do complete 3D models...

What cell count will you use?
Will it be laser cut, or manual cut?

[Basstronics]

Im thinking 3s, 427 prop?

Im still green in the hobby :) But I have goals.

It will be hand cut and home made hardware.

[Diegoboy]

Did you scale down the 21G2??

[Basstronics]

Yes sir.

Thats what the measurements came to given the scale.

I think the height needs to be adjusted larger and add a little more on the width of the tube- maybe another 1/8".

It was just a quick select all and scale.

If things are sounding good for the seasoned I will get my motor and get a full 3D model whipped up.

[Diegoboy]

I just learned that the 21FE tub is narrower than the 21G2. SO you scaled down the larger tub design!! Good job

[Diegoboy]

I like the 1st motor you linked to

[Basstronics]

Eh, cool!

The width didnt seem to bad. I think it will hold most batteries I would want to use.

I'm digging these:

I started on one, but I'm going to have to re-design/build the tub. As it stands now it'll barely fit a 2040 motor with cooling jacket. I basically designed it to fit a 3s 2200mah pack, but forgot to even consider motor size.

The bigger tub will be made to fit a 450 outrunner with water cooled mount.

The first motor you show the red one is the more powerful out of the 2. I run one of the other motors, The Typhoon in 3450kv at times. It has much thinner wires coming from the motor so they do get a bit warmer running on 3s lipos. The amps on the Typhoon is lower than the red motor. I think youll find the red one the better option, Their again these little 450 size motors are so cheap you can try both. Thats the fun of these mini / micro boats you can buy an assortment of motors to try with varying kv & have fun developing them for very little money. Thanks Martin.

I'm running the 3200kv turnigy one in my jet sprint and it has been super reliable.

[Alexgar]

i think your prop is to little on my 3s renegade rigger(16") i run a 531 and its pretty quick the motor is a 2600kv outruner

[martin]

Im running a 450 outrunner 3600kv on 3s with an Octura x435 sharpened & balanced prop, Although this is in a 15" deep v mono. Thanks Martin.

I would suggest a little wider than 2" on the tub. I will post pictures when I get the electronics in my new build(waiting on paint). It is 16.5" long x 2.125 wide x 1.25 high. It is a tight fit. The rear sponson tube does not go through the tub in order to allow room for batteries.

On the one I'm working on, I moved the rear sponson boom back to allow a 3s 2200mah pack to fit between the booms.

Any more details on yours? Is it a scaled down JAE with a bigger tub as well?

[Jim Bob]

Yes it is. I intend to run a 3s 2650 pack. I run 2150 zippy packs in my old rigger and only get about 4 minutes runtime and the battery would get warm, so I wanted to go with a litttle larger battery. In order to keep the CG where it needs to be on a 16" boat I needed to be able to run the battery close to the motor. The mounts I made for the rear are just as stable as the front boom, which is one piece. I also ran into an issue with putting the collars on the front boom, so I secure it with one screw through the bottom of the tub and front boom. Here are some photos.

What motor mount and strut are you using? Where'd you get the hatch?

[Jim Bob]

I made it all. Hatch is 1/32 plywood.

Oh man!
A mini rigger that I could run my small 3s 2200mah packs in would be killer!

What kind of speed are you getting out her??

[Jim Bob]

Have not run it yet, and don't have a wy to tell. No gps or radar.

[Brushless55]

I want one!
