My JAE FE Build Pictures

[longballlumber]

I figured with all of this JAE mania, I would build one to use as a P-Limited (P-Spec) boat. I decided to build my boat from the 21G2 (Nitro) plans. I wanted the option to make some changes to the boom tube location to aid in the packaging of the power system. I have been working on the build for awhile now so I am missing several pictures from the beginning stages… Anyhow, this is where I am at as of this morning. The tub is built and the rear sheeting (lower) is on. As far as the sponsons are concerned, I have the inside and outsides glued on with the beginning stages of sheeting.

These are the sponsons as of this morning...

This morning I started sanding the bottom sheeting of the tub to conform to the front angle of the nose or the front sheeting if you will. Since I need to use the nose of the boat to sand in the correct angle, I didn’t want to change the shape of the sides and the nose bulkhead. What I did was put masking tape on my sanding bar so it would only remove material the area that I wanted. It ended up working quite well

I also had to sand the sponson sheeting that was already glued on so that I could continue sheeting… As you can see in these pics I have glued the bottom rear porition of the sponson. Next will be the sponson top.

Next I had to put the front sheeting on making sure to leave a nice overhang as it transitions to the bottom. You will notice I am using two levels as straight edges to keep everything nice and straight. I have also been continually checking the boom tubes to make sure everything is nice and square. The last picture is the front of the tub being weighted down while the glue for the front sheeting is curing. Up to this point I have used 30 min epoxy on the entire hull. I feel like this will make the hull MUCH stronger in the end.

Looks really good!

Why I never thought to use a pair of levels as straight edges is beyond me. Great idea!

Hi Chuck,

I will be running the UL-1 motor and controller and plan to race in the P-Limited class.

WOW.... So I start this in sometime January this year... That is sad...LOL B)

Here are some pictures of it now. I tried running it twice yesterday. I have a few kinks to work out. I think the flex shaft was slipping in the Octura coupler. I guess it's the new boat blues. Now need to work up the courage to try and paint it with the Klass Kote that I bought in Toledo this year... :lol:

A couple of suggestions:

I see you are using bullet connectors on the batteries, but I've melted the solder on the stock motor connectors. Change them to bullets.

The stock UL-1 speed control is great but has high internal resistance. That matters if you are allowed to run other speed controls.

25C 4000 mah batteries get very hot. Try 40C or better batteries.

An S-15 prop detongued, back cut and cupped to 4 to 4.7 inches of pitch runs great.
