The inside, but seen from the other side.
Looking from the right side, looking to the left side, showing the inside of the hull.

Oh and : did you make 4 holes only ? Is there a hole in the front of the chamber ?

Hi there is a little hole up front see in my photo above this lets the air out when the boat fills up with water and then flips back over.... I will get a photo now hold.

I'm building an eco, almost the same as yours.
Nice to see one finished.

It's a cool looking boat that's for sure!! One thing i did to mine was go around the motor mount brace and water inlet and rudder holder with apoxy to streanthen and make sure they are sealed... another note on it is I had to use a servo slightly smaller in size than a standard servo for the steering as a normal size servo is to tall and won't fit enless you make the steering rod way longer than shown in the plans ...but this will move the servo up towards the front of the boat.

Have fun it's a sweet boat!

One thing to watch out for, and I don't know if this is a common thing or not, but the drive set on the ECO Power (a similar boat with the wings cut down) we had here fell to pieces in about 6 runs. The tailshaft ball-race seized, which ruined the shaft, and the skeg holding the stuffing tube into the boat cracked off, so the stuffing tube was left unsupported.

The solder joint along the length of the skeg failed - it looked like the solder hadn't fused to the skeg. From memory, the stuffing tube was brass and the skeg was thin stainless. To the best of my knowledge, you can't solder stainless with soft solder...

In the end we ripped out the original drive and I made a new all-stainless shaft assembly with PTFE shell bearings.

Hi the stuffing tube in this model is a shiny chrome and looks like it has brass inside it.... and the drive shaft is a rod with about 1 inch of flex shaft on one end.

Ok, it's a different setup then. Ignore what I said
