My old Lindberg model of the USS Melvin DD 680 has sunk at least twice in the model boat pond at Spencers, so I've decided to add about 1/2 inch to the bottom of the hull. It's an experiment. I think if the hull is a little bigger, the wind won't tip it over. I also upgraded the motor & rudder servo. Hope my experiment works.P/S seemed to work in the tub. I need to get it working properly as CMM Modelers is having a Warship Regatta at Spencer's Sunday,Sept 14th at 9 AM till noon

I need to stay off the internet, LOL
Noticed an ad for an Estate Sale. I went, I looked, and found (i.e. bought).
The Midwest Rowing Dinghy, Canadian Canoe, and Chesapeake Double Kayak are all nice boats.
They will look nice in a Diarama or just on display in my Home Office or Family Room.
I plan to do some work on the Cranberry Isle Lobster Yacht. It was not built/finished to run.
I'd like to open it up and put running gear and electronics in it to make it a working RC.
The front opens to access where the motor and electronics would go, but the rear is sealed tight with no access to attach a servo to the rudder.
Does anybody know where I could download the plans/instructions for this boat? I would like to see how the rear is constructed before attacking it.
Thanks for the help!

I hope that this helps; the plans show the rudder servo forward of the frame but I think it is better close to the rudder control arm. I use a NiMH battery laying beside the stuffing box and a counter weight on the opposite side. The original builder put a Y battery harness in so the boat could run off of two batteries for a longer duration. I just use one so as to give the brushed motor a rest .

Was asked for more info . So here are a few photos . This mini humidifier uses water only to generate fake smoke no smelly baby oil & varsol odor 50%-50% mix for Graupner smokers .I get the power to run unit from the receiver battery port as the unit uses a USD port to make it work so I got a old servo & cut the wire off it removed the signal white wire & used the black & red wires to power up unit . I have to turn model on then power up the Humidifier to start fake smoke put the cabin on model & away we go. Make sure Positive & Negative are put in proper receiver slots Please don't damage receiver if it's plugged in wrong.

According to the motor, ESC is underpowered. I needed at least A 60A ESC.

Many of you guys know that this is an old model that has been in the market for a long time and reproduced by many model companies like Dummas 1259 SC-1, ITC Model class craft 1:74 (plastic), Ringo Toy Corporation NC. C-5820200 1:74, Glenco model 1:74 (plastic) and a few others.
I don’t know if I have mentioned this before but I receive many request to build models for a local well know model company that is Model Expo owned by Marc Mosko, also owner of Model Shipways, Model Trailways, Model Airways and Guns of History.
This Subchaser is R/C but I never added all of the radios and servos since it was going to be shown on the Model Expo showcase.
So here is what I build with many scratch build items.
I hope you guys like it.

It’s a very nice and slick looking model, thank you for sharing that picture with us.
My kit is a Nauticurso from Brazil but Model Expo distributes it. There are so many things you could add to the model to make it look as real as possible.
“The Sub Chaser Archives” is the website I used for all of the reference need it.

I built this about 40 years ago, quite a rarity now I believe. Has not been in the water for about 30 years. I plan on bringing it up to date with speed controller and lipos as it used to use large heavy batteries and manual speed controller powered by servo. 👍

Camera Boat 5 uses another simple "pontoon" design with 90` rotating motor and fan unit with rudder which was added later. Gopro was mounted on rotating servo which gives 360` vision.
Camera operated with phone using Gopro App.
Regarding filming techniques etc. - Still plenty of issues to improve and overcome along the learning curve !.
Mni Tnx Graham for being there with "Bill & Ben" and Jon G7NFK for all your previous help and support since my stroke.

Part 1. ideal conditions; nearly 30°C, cool Bier at hand😜
Sea Scout built by Dad in the early sixties with a Taycol Target and 6V lead acid wet cells (very wet😡). Renovated and dragged into the 21st century over the last several months 😉
See Build Blog 'Sea Scout 'Jessica'' for details!
Motor: Propdrive 2830, 1000kV, 30mm 3 blade Raboesch prop. Quicrun 16BL30 (30A) ESC with BEC.
Tested with 3 battery types, all started with 99% measured capacity-
1. NiMh 4.2Ah 7.2V, nom. 408gm.
Result: Speed sedate (OK 😉scale river cruising!) No planing.
Max current: 3.6A
End status V / capacity left: At end of short run ca 3 mins. 7.78V 99%.
2. 2S LiPo 4.0Ah 7.4V nom. 257gm.
Result: Speed still sedate but due to lower batt weight at least the forefoot came out of the wet stuff! Max current: 4.1A
End status V / capacity left: At end of short run ca 3 mins. 8.25V 93%.
3. 3S LiPo 4.0Ah 11.1V nom. 315gm.
Result: Now we're getting somewhere!!😁
Good speed, manoeuvrability and planing 😊 Max current: 7.5A
End status: 11.95V 74% after several long runs, ca 20 mins total.
Estimated (extrapolated) endurance on a 4Ah LiPo around one hour - mostly 'full bore' - 'Pedal to the metal man' 😊

The competition!
https://www.youtube.com/watch?v=zPgYicA0yGw
Final run. (Beer was getting warm😁)
Cap'ns log entry:
Boat dead-weight w/o battery: 1.8kg.
Spray rails to be added!😲
Slight list to port to be trimmed.
Rudder servo to be reversed!!😲
Keel protection to be added: some scratches and flaking from stony sloping shore 🤔
Summary: much as expected👍 Forget anything less than 3S.
Anyone want to buy a batch (4) of new 2S 4Ah 45C Lipos? 'One careful owner'!
Happy boating people, Cheers Doug 😎
PS Many thanks to Camera girl Gisela 👍

Part 1. ideal conditions; nearly 30°C, cool Bier at hand😜
Sea Scout built by Dad in the early sixties with a Taycol Target and 6V lead acid wet cells (very wet😡). Renovated and dragged into the 21st century over the last several months 😉
See Build Blog 'Sea Scout 'Jessica'' for details!
Motor: Propdrive 2830, 1000kV, 30mm 3 blade Raboesch prop. Quicrun 16BL30 (30A) ESC with BEC.
Tested with 3 battery types, all started with 99% measured capacity-
1. NiMh 4.2Ah 7.2V, nom. 408gm.
Result: Speed sedate (OK 😉scale river cruising!) No planing.
Max current: 3.6A
End status V / capacity left: At end of short run ca 3 mins. 7.78V 99%.
2. 2S LiPo 4.0Ah 7.4V nom. 257gm.
Result: Speed still sedate but due to lower batt weight at least the forefoot came out of the wet stuff! Max current: 4.1A
End status V / capacity left: At end of short run ca 3 mins. 8.25V 93%.
3. 3S LiPo 4.0Ah 11.1V nom. 315gm.
Result: Now we're getting somewhere!!😁
Good speed, manoeuvrability and planing 😊 Max current: 7.5A
End status: 11.95V 74% after several long runs, ca 20 mins total.
Estimated (extrapolated) endurance on a 4Ah LiPo around one hour - mostly 'full bore' - 'Pedal to the metal man' 😊

The competition!
Final run. (Beer was getting warm😁)
Cap'ns log entry:
Boat dead-weight w/o battery: 1.8kg.
Spray rails to be added!😲
Slight list to port to be trimmed.
Rudder servo to be reversed!!😲
Keel protection to be added: some scratches and flaking from stony sloping shore 🤔
Summary: much as expected👍 Forget anything less than 3S.
Anyone want to buy a batch (4) of new 2S 4Ah 45C Lipos? 'One careful owner'!
Happy boating people, Cheers Doug 😎
PS Many thanks to Camera girl Gisela 👍

Hi Will,
The videos were all taken at stage 3. 'Now we're getting somewhere' with the 3S LiPo.
As depicted in the report there wasn't anything worth filming on either the 7.2V NiMh or the 7.4V 2S LiPo. Plod plod boring! I wasn't really surprised. I just wanted to know 😉
Cheers, Doug 😎

Finally got a good day, so raced down to the pond and threw the boat in. 2 problems, 1: battery had run down a bit with all the testing, and the new 18kg digital servo winch needed every bit of 4.8v, so functioned intermittently, meaning not much sail control, 2: jib boom needs a kicking strap to stop it 'skying' and tangling (knew it would happen but wasn't a worry). Apart from that, everything worked perfectly ( cheapo China Futaba knock -off rudder servo still worked fine on the low battery which is a bonus)
Sailed brilliantly like it did over 40 yrs ago, and as it's set will sail hands off on a reach, being nicely balanced, (even with the crappy jib,- which I had to make,- well actually my mother made for me,- back in 1980 after the original was stolen by a kid at the beach, while my back was turned😠) Funnily enough it was made on the same Bernina I used to sew (horrendously) the jib foot after trimming it for the boom a few days ago.
A few more things to improve and add, but pleased to have it back on the water. Another crap video, -seems to get blurry once it's been through the movie editor and You tube ) One day santa might bring me a Gopro, ("yeah right"!)

Looks like a perfect day. I find sailing very relaxing and quiet, with no engine/motor noise. Can be quite challenging though, especially when you need to bring it back in to the dock.

Hi the Graupner yachts are the best, I have a Gracia and she sails very nicely and such a pleasure to watch. She had a small change last year to the servos and works for ever on a 4 AA cell pack 2300mAh. I have a little less sail area and have a sail servo the same size as a standard servo and this copes OK.
regards Roy

Steering and reversing bucket servos fitted and operating. Final adjustments will be made once re-fitted after hull is finished.

Probably not Martin, but I'll figure something out, - perhaps some bituminised cloth made into a tube? Won't need much as the slots will be much smaller when it's all done. Just a bit large due to all the experiments, - plus they are quite high up, and I may be fitting a bilge pump. Was going to buy some boots from Ali Express, but the prices are stupid.
Ali Express is starting to get like HK, now that HK has been going down for a while,- every time you go back to buy the same item from the same seller, the price has gone up 1 or 2$. Everything's double the price it was 2 yrs ago and free shipping has been slowly disappearing! Going to be cheaper to build a real boat soon! Chinese are starting to take advantage I think, now that the govt has background control of A Exp and are probably trying to suck more money out of the sellers and A Exp as a whole, like they do with all large businesses there.

Managed to fit the steering servo for the jet unit, works quite well.

While I'm at it I have put up this video of my tug. I had been having problems with this and I completely replaced everything inside. Turns out the rudder servo was dodgy and the motor, a geared 500 was far too poky. It now performs beautifully and very quietly. Obviously it's an old Graupner Bugsier but refurbished by me to look a bit more like a British tug. The motor is a low noise 500 with direct drive mounted on a rubber sheet - the only noise is a whine from the esc.
