Lesro Magnum
« on: October 03, 2009, 09:13:02 AM »

What's in the box?

A very full box of bits...hull/deck/hatch mouldings in very good quality styrene, already trimmed and ready to fit together. A bag containing rx aerial tube, propshaft and prop, a bag containing all the internal mouldings for the servos, battery boxes, rudder linkages and ball joints, nice brass rudder and tube, a tube of styrene adhesive and a bag of instruction sheets and decals. There's even a moulded boat stand included in the kit.

IMHO...although there's no motor included, the kit is very good value for money. Sandra at Lesro looked after me very well, I received constant communications as my order was being processed, and Lesro gave me a very good deal.

Rich,

Just do not ask for advice as to what might be the best motor!!! {-) %%

Morning Ron,

Once bitten, twice shy mate!  ok2
I have a Tamiya 540 motor coming for the boat, and an eight cell nicad pack is on order as well. I'll try it with that, and then see about changing the motor later if I feel the need....

Flexi drives? Brushless motors? Water cooled thingies?  <*< <*< >>:-( <*< <*<

Well everything certainly use usable, nice to see a strong (Huco) coupling in there too.
Micro switch motor control?!!? ....  Haven't seen that for a few years.
( I'd round off the lower corners of the rudder for safety reasons! )
Nice brushless in there would be good.... I wonder if something like this would suffice?

Back to sanity(Martin...go away!!!) <*<

Made a start on the dry fit of a few bits, Tamiya motor, rudder and arm, radio switch, rudder servo and rx in temporary positions just to make sure things fit ok.

So far, so good...

Done a bit more today(inbetween watching the MotoGP and the F1(boring)...got the water cooling inlet/outlet pipes installed and changed the rudder linkage.

Tuesday PM update...

The top and bottom hull sections are now glued up. Instead of using plastic solvent, I used silicone sealant to give me a certain amount of flexibility when joining the two halves and also to give me an easier ride. I also added some pieces of closed cell foam, siliconed into place up in the bows for bouyancy...just in case. At the same time I siliconed the prop shaft and rudder tube/water cooling inlet pipe into position.

The flat now stinks of vinegar.... >:-o

Ballast needs to be on the left side if you need any at all Rich...

Use the BEC on the ESC, it will be fine on the voltage you're running, and with only one servo to pull round.

AFAIK, Richard is using an ESC, not a microswitch. You'd have to be mad to use the latter on a fast electric these days surely?

A linear regulator is not going to get very hot dropping a couple of volts and powering one servo. Switchmode BEC's are great, especially for submarines or a boat running a high voltage (over 12 volts), but I see no benefit in forking out for another gadget when you have an adequate device built in already.

My heat comments where about resistor speed controllers not bec's as I thought that was what he had.

I'm building this more or less from the box chaps, I have added water cooling admittedly, but that's about the only deviation from the kit plans. I'm not getting into circuit racing with it, so the instructions say battery pack on the right, so that's where I've put it.

As for bec's and such stuff...no thanks, far too technical for me and this boat.

It's what they sue for a warp drive in Star Trek, Richard. Martin is pulling your leg.

Nothing technical about BEC's I assure you, just plug and play. It can't get any simpler, and you only have the one battery pack to worry about.

In the sub Andy....yes, but not in this little fella. This purely for fun after work, just until the Dragonfish is ready for operational duty.
