First Kits
« on: April 03, 2020, 04:03:40 PM »


Hi All,


Thanks for letting me become a member of this site. It looks like it is full of lots of really useful information.


My 10, nearly 11 year old son recently went with one of his friends to have a go at model boating. His friend, friends father and brother have all been boating for ages. My son never been before. Now he has become quite interested in it. And after a few chats with his friends father, who has been very helpful, I decided to get my son a boat.


We decided to buy an Aero-naut Classic Sports Boat kit. I'm sure he will need some help making it, and we will build it together. I also, possibly rashly, decided to get an Aero-naut Jenny kit too! Something for me to play with, so we can both have something to take to the water.


Over the next few weeks, I'll start buying the rest of the kit we need, at least to complete the first boat. Looks like this s a good place to look to see what other kit people use/recommend.


I'll try and keep a record of how we get on with both boats. I see a few people have done the same.

Hi Klunk,


We are just North of Luton.
I believe that my son was taken to one of your clubs meetings at Wardown Park.


Good to make contact with you! Maybe we can meet face to face at some point soon, once the Covid restrictions are lifted!

Hi Martin,


Thanks for the welcome.
Hopefully, two links to pictures below will work!


As it's not Luke's birthday for a few weeks, they will have to stay in the boxes for a while. Unless of course the boredom of isolation proves too much!

Hi Rich
Classic is a good place to start, and gives great little model.
Check out my build of it here https://www.modelboatmayhem.co.uk/forum/index.php/topic,57838.msg602811.html#msg602811http://
And please do you self the favour and replace the propshaft with some thing better, you can see my choice of parts in the link.

Hi Carsten
Thanks for you link. Always good to see other peoples builds! I have seen a couple of builders say the prop shaft needs to be better. Did the one you use fit as a replacement without too much bother? Ie will a relative novice make the change without too many problems? I assume it's better to fit from the start than try and fit once the boat is built?
I also notice you fitted a Universal joint rather than the flex hose as a joint between shaft and motor.
I think I am planning to install a brushless set up. But will start with NiMh batteries, as I have a few of those already from buggys.
Was suggested this motor - Turnigy L2210A-1650 Brushless Motor (180w) - but I wonder if its a bit too much. Maybe a 1200kV would be better to start with.
We will read through your build post several times before we start!
Do you mind if I as what varnish and paint you used?

Thanks

It is easy to fit a larger tube, you can measure the old tube and the new tube and then remove Ĺ of this from each part of the keel.
Choice of BL: If you use Turnigy L2210A-1650 with 7.2V NimH you will have approx 11800rpm where I'm using a BL with 1380Kv, with Lipo it gives for 2S approx 10200rmp and for 3S approx 15300rpm, so just stay with that choice, your battery will also add some weight that will slow it a bit down. It sails great and scale like speed with the 2S, with 3S it is too fast and gets unstable in rough water.

Varnish: I'm using Junckers Skibslak,It's a Danish Brand of 1K maritime high gloss, you can use any maritime type of 1K varnish.
Paint: It is Vallejo water based, first a couple layers of varnish with a rubdown between, then the colour and then some layers of varnish on top of the that.

Thanks. I assume I'll also need to swap the prop, if I swap the shaft?

Yes you have to get another prop, I'm using a 30mm hydroprop from Graupner No. 2299.30 and please use a good quality UJ instead of that flimsy piece of silicon tube, it will not stand for the BL setup.

Hi Rich,


Iíve just started on the Aeronaut Jenny, first boat build for about 20 years since I did one with my dad so will see how it goes. If I can find somewhere to host the images Iíll put some up from the build so far. Have learnt a few things not to do but all part of the experience! I struggled a bit with the hull stringers as itís a real curve at the front of the boat and getting them to hold was difficult, cable ties seemed to work for me but not seen anyone else use that method online so possibly not a normal approach.


Would recommend getting some ratchet clamps, normal spring clamps really struggled to hold the hull panels in place.


To the rest of the community I had a few questions for help (sorry if some seam really obvious):
I have gone for the Aeronaut 650 Race Motor, so went brushed. I note on my old boat (now v old) we fitted suppression capacitors. Are these not needed now with modern controllers as the new motor didnít come with any?

It a thanks for info on the paint, I was going to ask about best paint, varnish people use and any recommendations they have that ship in the UK. I notice aeronaut recommend covering the boat in a coat of clear boat lacquer, is this what most people do?

I struggled to find an alternative prop shaft the right size for the Jenny online, itís a 380 mm tube with a 350 mm shaft. Did find this one online although itís a bit short

https://howesmodels.co.uk/product/13-inch-330mm-m4-boat-propeller-shaft-stainless-steel/


Would it make a significant difference to the as supplied shaft and is that one above any good or are there other brandís people use?


Have to say a big thank you to people who post build blogs, really helped a lot when scratching by head looking at build instructions and wanting to double check for my own sanity I was doing the right thing. Will try and also do the same, even if the build isnít quite to the same standard  :-)

Simon - just a couple of comments. When fitting stringers and panels (assume you mean skins?) You will find it much easier to hold them in place and take stress out of the hull assembly if you steam  (some prefer to soak) to the curve beforehand before gluing. I use a kettle with the top open and wear oven gloves to hold to the bend required.

As regards the prop shaft I assume you mean 380 shaft and 350 tube! Anyway, you can always get a longer one and cut it down.

Hi Chris, thanks good advice will try that next time. And yes youíre right, I did get the tube and shaft dimensions the wrong way round, that would have been an interesting installation based on my original dimensions I stated 😀


Iíll try and get some build pictures up this weekend, they were a bit rushed when I took them, but can show everyone  what not to do 😃

Sorry itís been a long time without any update. Work has been extremely busy and had some parts issues that I forgot to order and then with things as they are right now deliveryís are understandably a bit delayed.



I originally hadnít planned these photos so not the best. This is just a test to see if posting works.

Ah so that worked, well ok unconventional I know but I really struggled to get the stringers to stay in place, steaming them sounded a good idea and will try for next time. I seemed to work ok except at the front where I had an issue getting them in tight. Afterwards I found some ratchet clamps that held them well while gluing.

I the hull went on ok but I taped it together too tight on the practice fit and never spotted on refitting that it hadnít gone back down flush so ended up with a small gap between the hull and the centre of the frame  :((  Also had some difficulty getting everything perfectly aligned at the front. Anyway onto the sides and that was not easy. The method in the instructions of putting both on together, just couldnít get it to work, so did one at a time and weighted it down as instructed and that went ok.

Needed a bit of filler at the front which is now smoothed down. As recommended bought a new prop shaft and that is about to be installed so will post some updates as the interior fit out proceeds.

Hi Simon, thanks for your updates.
My son's birthday is on Tuesday, so I hope we will start building soon.
I'm hoping I've got most the bits I need, although electronics I ordered are delayed!
I'll check I've got plenty of tiewraps.

The zip ties are a good idea Simon. Especially the reusable ones  :-))
