Proboat Aplha - ready to run.......model of Patrol Boat Riverine used by US Navy, Vietnam between 1967-72. Basic 1/18 scale able to attach small action figures for added dimension, model always look better with crew.
Great starter....already looking at larger scale military kits and really impressed with Deans Marine product range, unfortunatly little options to explore in Australia....so have to order most stuff in....vids will get better with experience...stay tuned.😉
Clyde Puffer - Posted: 1 month ago by lesliebreame

At Illfracombe pond last week . Have made an automatic feed water system for my coal fired Puffer and went to the pond to try it out. I think it needs bigger capacity pump as there was very little water in the boiler after 3/4 hour running. Gordons hydro is beating me up as usual !!! Les Breame
If you go to page 11 video blog and half way down there are 2 better videos of the Schumschimmer taken last year on its first voyage [ for Gordon that is ] I think he bought it on ebay . Its very light made of thin plastic carries a brush-less motor and modern batteries both of which i dont know the details but could find out if you wish.The smallest leaf or twig causes it to come off the foils which is why in the video you see it reversing to clear them.

Correction on details of Hydro. Gordon tells me the boat is Japanese from the 1980's made by Gunze Sangyo . It has the original Mabuchi motor and mechanical speed wiper controller [gets very hot ! ] . The hull is fine glass fibre not plastic.
Only 2nd run of "IMARA Tug", my lad did the shaky video. (O well) Nice model lots of ballast, batteries, MARX Hectoperm motor for huge power reserve. Running on electric but Cheddar Proteus steam plant also fits in instead with ABC boiler control. plan for the future to try this never run not even on air yet!
great job on the model.Runs nice too.Nice to see lots of lights.Will look great at night.BTW anybody check to see if the Canada geese had their passports.
Modav Huntsman 31 - Posted: 2 months ago by Will-I-Am

Built originally in 1973 from a modav kit and powered by an Enya 35bbiii. Now running a 3548 brushless motor and 5800 3 cell lipo. Model in video was running an x35 prop with +/- 20 degrees of rudder, very sensitive on turns. Today's run was on x40 prop considerably faster with reduced rudder throw of +/- 15 degrees. Current draw was 30 amps max watts 376. Still too sensitive on turns.
Very nice boat I am in the process of restoring one myself. Could you reduce the size of the rudder, may increase straight line speed, and calm the turns.
Looks the same as the one in my Sea Scout William. For size idea; the prop is 35mm. And it works beautifully, see trial vid. https://youtu.be/zPgYicA0yGw Cheers, Doug 😎
Hi William, S, X35 !? No idea😲 I assume they are terms from the racing world which I have no particular interest in. My intention wasn't to make her into an offshore racer. As it is she's well over scale speed, but fun to run, and that's what counts ain' it? 😉 Gives a good long run time, 1 hour plus, using a Propdrive 2830 BL and a 3S 4Ah battery. All up weight 1974gm. LoA 24", beam 8.5". My prop is simply a 35mm ca 14 pitch from Raboesch. Actually wanted the one with a blunter hub but they weren't available when I wanted it. The pointed hub variant is actually more like as fitted to larger naval units in WW2. Sorry🤔 Cheers, Doug 😎
Doug, Thanks for the reply, as far as I was aware the S type plastic props were less pitch than the X type plastic props. If your 35 mm metal prop is 1.4 pitch then it is similar to the X35 plastic prop I used in the first video. I think I need to investigate diameters and pitch a little more. Last week running my Huntsman I had an X40 plastic prop on and it was too large and way too fast, a friend running a 34 inch fire launch runs an X 35 so I may go back to look at a 😎35 mm dia metal prop and look at the pitch. Regards Ian
Aha! Now I've learned something too👍 Thanks William Actually I've been busily changing all my 'frayed' 😲 plastic props for cast brass ones. Cheers, Doug
Tug Brooklyn Tub Test! - Posted: 2 months ago by figtree7nts

Just a 2 minute tub test. While adding her ballast! She's a beast! She must weigh in at 9 or 10 pounds!😲
Eat more spinach Ed😁 I know, I know - I hate it as well😉 Would be glad to help but - wrong side of the pond 😭 Build a trailer for her and I'll send you an RC Beach Buggy to pull it! Happy pond trials, cheers, Doug 😎
Thanks Ron. I have tried to be most particular with scale speed and waterline. I used 1.2kg of ballast carefully laid out whilst hull was floating in the bath. Once in place I secured it with expanding foam.
