Jae 12

[teach]

Well here goes. Be gentle this is my first shot at a build thread.

JAE .12 rigger by Zippkits. $50 shipped to your door. Comes with everything to build a "roller".

Built per instructions until installing the lower tri stock pieces used to support the tube bottom. The location for the motor mount just won't work for FE in my opinion.



Cut off the ears of the mount and extended the tri stock to meet the boom supports.



I left the center tub suport in until I felt the tub would not warp. Second guessing myself I would have just left it out to begin with.



I wanted a single hatch so I took some 3/8 square balsa and used a belt sander to make them into tristock. Glued them in and sanded flush with the top of the tub.



I cut the tub top so I could use the top and still use a single hatch. Here is what it looks like with the tub top taped on.



Now for the bad news (for me anyways. 1 1/2" wide. That's going to be tough to get the gear in.

I really wanted to use one of the P spec systems but after seeing how small it is, I need some help from you folks with smaller cans. What would work?

I also plan to build two of these someday so I'll be following your thread with anticipation... What were the quality of the kits and the instructions?

This is a 2s boat guys, use a 4s and you may have a submarine in your hands. you will be in trouble if the hull isn't tall enough to fit a battery pack... how tall is it? You'll ned around 1 3/4 to stand a cell...
Maybe if you built the top reinforcement a bit different... be sure to have the system that you'll be using available to try it in there. As far as your build quality goes, I am not an expert builder but it looks good to me.

Ya I have to give up on the 4s idea.1 1/2 is the tube depth.

I really should have waited for the .21 to come out....but waiting sucks. If I never get a power system in it that's ok with me. I like building it so far.

The instructions are top notch. The quality is even better. They even send a few 90' squares to help.

Do you mean 1.5 inches deep? Half inch sounds a bit extreme...

Is Zippkits planning a .21? When? hmmmm

Coming soon to a... website near you.
They are in Beta test already.

Guys, you need to understand this was a NITRO boat by design. They don't need to have a tub that is 1.5" deep. It only needs to be deep enough for servos and fuel. Most nitro racers use metal fuel cells, so they can be made to any shape to achive the correct volume.

Another point about waiting until the .21 comes out. I think your all going to be disappointed to know the tub height on the .21 version is not going to be much taller. The hull will be longer, but the tub height is not going to be taller than .75"

These JAE boats are not great for converting to FE. Your better be is use the design critera implimented on the JAE and bulid your own.

Mike you wrote this to me on anther thread about this hull???

Rich,
The .12 tub dims are 22.625 Long X 2.5 Wide X 1.4375 High
Mike

So, If the tub on the .12 is 1.43" HIGH,,, how is the .21 going to be .75" tall??? Also why say the .12 tub is .5" high?? These are not accurate....

22.625 Long X 2.5 Wide X 1.4375 THESE ARE THE CORRECT SPEC'S.......... NO 1/2" TUB......

I am sure that a Fiegao 380 size motor and 2x 2s 2200 or 2600 packs will be fine... IF i have to design a bubble hatch for the FE user,, it wont take long to make a mold and start making them in epoxy/glass..That would make it easy to tape and provide more clearence for the motor.. As soon as I get my kits I will start working on a hatch to make a mold...... These will be FAST little boats if setup with proper equipment...

Good catch. Fixxed.

Sorry sir it was just a missed number at midnight.

Txboatpilot is right,

I didn't re confirm with the dims I posted yesterday... My mistake

Eventhough, I still stand by my comment about converting to FE. I don't have the .21 dims right in front of me, but I am pretty sure the tub height is the same as the .12 hull. If I remember when I am at work on Monday, I will reconfirm the .21 tub height.

Bottom line is, as currently designed, the .12 boat will be tought to get 4S1P to power a UL, SV, or BJ power system. I am also of the opinion that the .12 boat is too short, mainly for packaging this power system. The boat can handle the speed, but it's packaging all of the components. Another thought to keep in mind, WILL THE BOAT FLOAT? I think that you will find the weight of a controller, 4S1P batteries, and motor (w/cooling jacket) will out weight a .12 size motor and a fuel cell that hods (about) 6 oz of fuel.

I think that you will find the same issues with the .21 size boat regarding tub height and power systems weight...

You loose one sponson on either of these boats and you will be looking at the bottom of the lake for your boat.

Just my $.02 guys
