📝 Aliphatic resin glue

Without knowing the exact type of glue it is difficult to answer your question. My immediate thought wea cascamite but you mention a bottle which rather rules this out. Most glues have a shelf life and some require you to coat one surface with the glue and the other surface with a setting agent. Many also require that you clamp the two surfaces until set (often 24hrs). As they are water based temperature will play a part but more in respect of the final strength.
I did Google and found a very informative article on aliphatic glues which may help
en.wikipedia.org/wiki/Wood_glue
I recall dad made me a model boat out of plywood (tea chest) and that was glued with cascamite. I can still recognise the smell after all these years and sailed the model for several years.

📝 LiPo Batteries

Could it be that your settings are for other than a LiPo say Life? I have a similar unit and have to select the battery type with a button. The small plug in checker should show each cell voltage then the overall voltage.As long as each cell is below 4.2v (more likely 4.15v) all is ok.

📝 LiPo Batteries

Just an additional comment re your charger. It has a setting for Hv LiPos which will charge that Hv type of battery to 4.35v. In your case you need to select the LiPo option for 4.2 v max. Also make sure 3 cells are selected. What instrument gave you a voltage of 14.1volts? If it was ther charger it could be faulty. A check with another voltmeter should confirm this. If it is faulty the max charging current might be faulty also. If you need to change I use a Giant Power Intelligent Balance Charger G6AC.

📝 LiPo Batteries
10 days ago by dave976 ( Lieutenant)

Sorry to have confused. I was referring to the min discharge voltage. Modern higher capacity batteries now recommend a min discharge of 3.5v per cell. Earlier lower capacity batteries recommended 3v per cell. I use 3.5v as my cut off voltage to preserve the life of my batteries. Suitable ESC's have this as a default setting but are also adjustable to other cut-off voltages. The ESC doesn't cut off completely it just limits the current draw to a sfe low level to allow you to return the model to shore.

That charger is quite suitable for your purpose providing you use the main connector and the smaller white balace charge lead.

📝 LiPo Batteries
11 days ago by dave976 ( Lieutenant)

If I could just add to the very good advice already given. LiPos will be damaged if discharged below 3v or higher, this damage is cumulative and involves an irreversible chemical change in the battery. You can buy add on devices that sound a warning when the voltage of a cell drops below the set min voltage but many ESC's now come with built in protection which does a much better job. Water is best kept out of our models whatever battery system we use. I always place all my electrics as high inside the hull as possible as water will always find a way in.

Beautiful model. We have an almost identical model in our club and that too was built from an enlargement of the plan in FJ Camm's Model Boat Building. I agree the model sails really well and like yours attracts much interest when sailed. It's now with its third club member and I restored leaks in the hull earlier this year by covering the whole hull in fibreglass cloth as the ply used in the keel construction had delaminated too far. Now 100% watertight so worth the effort spent. Pic attached for comparison as well as a page from the book showing the outline.

📝 Motor and esc problem
19 days ago by dave976 ( Lieutenant)
Lieutenant)
A motor can run off a range of voltages but it has a max rating regarding the power it can produce. This is measured in watts and is the product of the voltage applied and the current drawn. So 12v times 5amps = 60watts.
Increasing either voltage or amps increase the wattage and if you exceed the max the motor will overheat. I suspect your coarse prop is the problem as it is overloading the motor and increasing the current draw. If you change the prop to a smaller diameter and less pitch it will reduce the current drawn and your model will perform much better. Three bladed brass props will give good results and I would avoid the two bladed racing props. As a general guide the prop diameter should be less than the diameter of the motor casing.
It is a case of trial and selection so good luck.

📝 JOHN HEMMENS LADY JANE
20 days ago by dave976 ( Lieutenant)
Lieutenant)
Hi Andy
I have to agree with Nickthesteam on his comments re your boiler and engine.
Steam plants do need regular maintenance and if in a similar condition to the Lady Jane there is a real possibility that most of the pipes will be blocked and need dismantling and cleaning. The boiler is likely to be heavily scaled inside and you should not attempt to steam it until it has been checked and cleaned and then water Pressure tested by a registered boiler tester. For your own safety please do not attempt to steam the boiler until this safety test has been completed. The fact that the water tank was full of solidified gunk suggests the previous owner was not cleaning down after use. The Hemmens units are well made and usually perform very well if used as designed.
Hope you can resolve all the issues and get the unit into working condition.

📝 Where are you allowed to use with out belonging to a club?
21 days ago by dave976 ( Lieutenant)
Lieutenant)
You may wish to look at the Useful Links section on this site and scroll to Places. This is a list of Model Boat Clubs and you may see one near your location. Joining a club will help you sail your models safely and at a place that allows model boats, plus you will have the help and expertise of dedicated modellers to help you resolve any issues. Others have mentioned the importance of 3rd part liability insurance which really is a must in our claim society.
Nice looking models and please ask on this site if you need help and advice in the preparation, but please use a fresh blog with an appropriate heading.
Good luck

📝 Water up shaft..
24 days ago by dave976 ( Lieutenant)
Lieutenant)
You should have a thrust washer at either end of your prop shaft to take the horizontal thrust as the prop revolves fwd or rev. This should be a close fit to the bearing and the prop shaft. Use nylon /brass or stainless steel. At one time Rizla cigarette papers were used to set the gap. You should also fit a lock nut between the washer and prop to avoid the prop from spinning off. Same at the other end if the shaft is threaded. This with thin grease/oil will help keep the water from seeping into your model. There is a more efficient method using a stuffing box on the shaft at the motor end but this may not be needed for your occasional use model.
Please ask if you need further info

I agree Nerys. Built in large numbers by our friends over the pond and used to ship vast amounts of goods and munitions in our time of need. They were I believe stacked high on deck with munitions and vehicles and my example depicts a typical post war livery version. May be when I complete the Robert E Peary it will be in wartime livery complete with deck cargo, I seem to remember there were many military scale vehicles which my friend Bill Handy had purchased.

Yes but not by me. Built some years ago by my friend Bill who now resides in a care home. I suspect he made a plug and mould and cast his hull in fibreglass. The motor is a 55 brushless and the prop a 3 blade brass which he made himself. It requires about 2lb of lead to ballast and this is held in gaffer tape and marked for position so is removeable to make transport much easier and helps avoid damage. I have a Dean's kit of the Robert E Peary part built by another club member who found it too challenging. On the back burner with several other models. I need more hours in the day.

This model has sailed with our club for many years and evokes many memories from the 1950/60's when this type of speed boat was raced round the bays in the UK and elsewhere. Cindy and friends seem to be immune to the risks both from the water and the sun. I intend to replace the motor with a small brushless and use a LiPo to reduce the overall weight and improve the performance.

Another model acquired from a former club member. Modelled on the Whitby Bay pleasure cruiser and populated with scale holidaymakers. A delightful small model that always attracts attention. The prop is a racing type two blade which I will replace with brass 3 blade and replace the motor with a 555 type as speed is not a feature of this model. The rudder is also too deep and gets damaged in transit so I will replace or modify to a smaller size.

Recently acquired from a fellow club member. I had restored the model some years ago to display on our club stand but it's in need of some more tlc and I believe I will put a small brushless motor and replace the prop. My Sea Queen sails much better with a brushless.

It's a Vosper Sea Plane Tender.
Google Vosper Sea Plane Tender. There are a few variants but your model certainly fits the general details. In the 1950's we tended to do much scratch building and it is possible your Grandfather did just that. As you say it is not a scale representation but follows the general design and shape. There were several manufacturers around and some plans so unless you have further details it will be difficult to decide its provenance. It has certainly restored to a nice model and will draw attention when you sail. We have one in our club and I attach a pic for info.
