It's a sad day!. by BOATSHED Fleet Admiral!   Posted: 8 days ago
I used to use Blackheath pond South London but last time I went there with a boat I had just come off the pond after clipping the pond side and bending my prop shaft,The local park ranger pulled up in a van after someone making a complaint. The boat isn't noisy as the cooling also runs out of the exhaust. He told me I was very lucky as if he had actually seen it running on the pond it was an £80.00 fine. He saw me lifting it off the water but engine wasn't running. I don't understand it as some of the boats I have seen running with brushless scream more than my 26cc PT109. I do have a Proboat Miss Geico she isn't too bad on noise, I also have a Graupner Rhode Island with a brushless outboard but she is still untried on water up to now.

MAS 562 update by CB90 Commander   Posted: 20 days ago
Skinned the frames added deck and splash rail also started on cabin and superstructure, added rudder and installed twin brushed Graupner 600 motors via Graupner style direct couplings. Motor mounting system through a bulkhead gives extra support to motors which mount on to end of the shafts. currently adding a rudder servo mount, as rudder is a close copy of the real boat's and still functional.

47" Fireboat power question by rolfman2000 Fleet Admiral!   Posted: 23 days ago
Thanks Ron. I always though the I'v times the voltage gave the prop revs. As my G-60 is only a 500kv, then my 4s at 14volts should be sufficient, but a 3s might be a bit short at 11.1v. But I will give the Graupner 50mm hydro a try, which at the least is a place to start from. Once again, thanks for the advice Ron. Happy sailing, Dave W😊

47" Fireboat power question by ronrees Sub-Lieutenant   Posted: 23 days ago
Hi Rolfman, This one is for you.....I wouldn't fit a 6 cell Li-Po to run your 47 inch fireboat!..It would be uncontrollable almost, even if you throttled back. That relates to an output speed in excess of 11,000 rpm at the prop. Safer to try a 5 cell (9,250rpm) or even a 4 cell (7,400) initially. Also see my message to Shaun. I use a G60 in mine with 4 cells which is ample, the extra battery pack in Shauns will double the running time. I only use 1 cell. I use a 50mm two blade Hydro Graupner prop (From Gliders UK), it could handle a bigger one but everything starts to get a bit warm!! Cheers......Ron.

Have finally got round to sanding the deck edge to blend into the hull using permagrit files and 200grit sand paper ready for its couple of coats of a water based varnish before applying the paint Ron

HMS HOOD by Trumpeter by cormorant Fleet Admiral!   Posted: 1 month ago
Hi Peter If you look at this website http://www.hmshood.com/hoodtoday/models/trumpeter/trumpeter2... you will see that there are enough incorrect items to drive you mad. I have decided to get it as accurate as the kit allows. I have installed a Graupner 6v smoke generator in each funnel with a computer fan at the base of each - yet to be tested. I propose to switch them on and off with a receiver controlled switch. I would like to be able to colour the smoke but have yet to find the correct formula. Steve

The deck has been fitted today after dry test fit before glueing. The timber framing and underside of the ply decking was coated in a water based varnish before applying the titebond 2 wood glue. Used a number of clamps and bungee cords to hold the deck down.
