Hyper - Looks pretty good to me. Glad to see other builders out there. The ready to runs just aren't as satisfying.

One thing that I see that might give you a problem is the size of your radio box. It looks really small. But, then again I have seen some with tiny radio boxes and they seem to get everything in there. Is your engine mounted? It looks like you might have to lean it towards the back of the boat a little more so that your flex shaft can exit the transom without any weird bends.

Like me, you chose to build your first boat. You'll learn alot along the way.

The 3 ply plywood formers that you are using is not a recommended quality for boats. 5 ply aircraft grade birch is the norm. Since you have already built to this stage, be sure that you put several coats of epoxy an all the interior surfaces to keep water from soaking into the wood. That stuff will soak up water like a sponge and fall apart shortly after. I would also suggest that you reinforce the keel seam on the interior with some fiberglass cloth (2 oz cloth is good). Do the same where the transom meets the bottom sheeting. The engine looks to be to far back, you will have a problem getting the drive line in place without putting sharp bends in the flex shaft. It also looks like you will have to run the shaft log through the radio box, further restricting the space you have for the radio gear. With the miniaturization of todays receivers and servos you may get away with it. I'd suggest a very small servo for the throttle and nearly as small for the rudder. A 600 to 700 mah nickle metal hydride battery will also save space. Many people think you need a servo strong enough to open a barn door for the rudder when the opposite is true. A .21 powered boat will do very well with a 40 oz. in. servo. Especially at the speeds you will be seeing. Look at the Hi Tec HS 81 for the throttle and the HS225 for the rudder. They will provide more than enough torque for your purposes.

Just being honest and trying to get you on the right track.

Good call on the plywood John. I also agree on the epoxy coating, 30 minute or slower epoxy would be best.

Before getting too far on the deck, do a test fit of the exhaust and other hardware. The ability to get at things once they are installed can be a problem ot just putting them in after you have finished the hull work could be a challenge.

my exhaust is gona sit on the deck alongside the engine, im just using the buggy exhaust caus ive got a spare one.
i will make sure the hull and all the internals have a good coat of epoxy so i dont get water damage, and the radio gear..... i think the gear im using should fit no trouble. thanks for the feedback, at least i no i am on the rite track

ok, i did what u said i put the engine on more of a lean so the flex cable wont have to much of a bend in it, i also cut the servos in to the radio box and it all fits nicely..... i think

would a heat sink work for a boat? are there advantages/disadvantages?

Heat sink heads work fine in boats, most of the time better than in a 4-wheeler as they get more air and cooler air coming from off the water. The only downside that the Pro's have found is more loss of speed in the corners than water-cooled heads. I would only use them myself for up to .21's as anything that size and under really don't need water cooling. My .12's run so cool that I took the top 3 fins off a heat sink and it still wasn't getting warm!
The downside also is how the engines come equipped. SG cranks are all but impossible to hook up to a flywheel and flex cable collet. some of the carbs are too small for us. We can use whatever will fit in the hole, the car guys are restricted by ROAR, IFMAR, etc.
