That's another thing I haven't noticed with lithium batteries- they don't get hot when charged unless you're seriously overdoing it. I tend to charge at 1c, some batteries can be charged at higher rates, but I think it shortens their cycle life.

Bonding the lead weight in the bottom of the hull with polyester resin. I used plasticine to build a damn for this lessoned learned, it a pain to get off. Blue Tac or similar works much better.

The watertight box.  I prefer using  Simmering seals to seal water tight shafts on subs, so I made some holders out of aluminium rod to fit 6x11mm seals. I used Posilock connectors as through hull hull connector to bring cables put of the the WTC for servos, lights etc..

Bonding the WTBox into the lower hull is probably the most important step in building this model. Naturally the box needs to be level and at just the right position so the motor output shafts line up with the prop shafts (though if you use universal coupling rather than the ridged couplings supplied you have a little leeway). However more importantly if the box is bonded in too low you wont be able to get the piston tanks in, and if its too high you wont be able to submerge from a scale waterline. The instruction say that the top of the box should be 26mm from the top of the lower hull, and its well worth measuring this a few times.







Once I got the water tight box into a position I was happy with I spot glued it in 4 places to hold it whilst I went about bonding it in with Polyester resin.

You will need to have a word with Mr Perrott, and cross his palm with silver.

There are details of how to grow your own in the files section on the Dive-in FB page. I'd say a small lathe would be useful for machining some of the parts, although a lot of bits look like they can be made using standard hand tools.

That's a rather large Gap between upper and lower Hulls...

They all seem to be like that (even the product pictures on the Engel website). They will pull together with compression though, but I decided not to put any tension into the hull.

I know you said you have it under No tension.

If it was compressed would this no effect the way the top sits elsewhere?
And surely it would want to come apart at the bow, even with the retaining clasp.

Is it going to be Ron Perrott Torps
Or are you going to use the resource Andy mentioned?

No the hull seems to fit all around reasonably well with the bow compressed. The Engel locking method for the two halves is a bolt through the top and bottom which pulls the bow together.
Torps are top secret till I get them working.

Think the missile hatches have working missiles planned, don't they?
