Would be good to have missiles firing but think it would fall foul of the uk firearms laws think there was something on here writen by an ex bobbie a few months (years back)

There's been debate over operating torpedoes and missiles fired from model boats/subs for donkeys years now...if you don't go mad with them and have the things firing forty feet up in the air, or capable of blowing up another ship, my thoughts are that you'd be ok. My torpedoes that are going in the Akula will only fire about ten/fifteen feet...enough to look good, but incapable of damaging much if they do hit anything. Look at Mick Higgott's...they look terrific, but they wouldn't even ruffle a duck's feathers.

Don't necessarily have to have ballistics to get a missile going.

However there aren't much in the way of rules and regs with regard to model rockets when kept small. Just basic common sense- no launching them in densely populated areas for instance, keep a safe distance from spectators etc. private land is more restricted than common land.

The model rocket boys are the best people to speak to about all this.

Exactly...if you start firing missiles and/or torpedoes down at your local lake with Joe Public swarming all over the place, local wildlife and loads of other boats on the water, then be prepared for complaints. Just keep it low profile and you should be ok.

I never find lithium batteries getting warm when being charged. I always charge at 1 c or lower anyway, I think it helps the cycle life.

Is that a bow thruster I see there? I take it the motor to drive the unit is back in the WTC and that brass rod just drives the mechanics inside the thruster. Also, does the position of the thruster being off centre make any noticeable difference to thrust on either side?

Hi Adam, it's the standard 14/16 paddle bow thruster made by Raboesch

I can imagine the bow thruster body being off centre will make any differance. Of course I haven't tried it yet.

Could always use small centrifugal pumps like the Spanish modellers did a few years back. They used brushed versions but you can get brushless versions now, and they cost peanuts if you buy them direct from China on ebay.

Probably be a bit slower than a dedicated bow thruster unit, put you can use small holes which are more discrete.

centrifugal pumps only flow in one direction irrespective of which way they rotate

one scroll case, two radial outlets, flaps control flow from either.
Flows in pump is always one way, but exits either side dependant on flap position.
simple flap switch control, Left or right, no reversal to motor.

one suggestion of at least a dozen solutions to the use of centrifugal pumps as thrusters in model boats, no problem at all.
