Get some pictures up Stavros

I was thinking just how many people have done this type of conversion???
would be nice if companys like Impact worked with modellers like us to improve there models, seeing as a fair few of us have taken it apart and remoulded it into a nicer model.

do you not think that even with a 20 amp esc i still might blow the 15 a fuse? and also does the esc draw more current the larger it gets? therefore negating any pwer improvements.
regards Steve

It might still blow the 15A fuse, but you would have another 5 amps to play with - so could try a 20A fuse. The amount of current drawn by the ESC itself is more or less constant regardless of rating.

Barrie,
thanks for that, this is the way i am now inclined to go, i will try 20a esc & 20a in line fuse (as this is the nearest ampage i can get) but it should still give the esc protection.
This is my first r/c motor fitting, boy what a learning curve! Bottomless pockets required eh!
Regards Steve

I think including the cost of my model ive spent around the best part of £120 on my little Severn.
Im in the process of building a new super structure out of thinner plasticard which is proving to be difficult.

Thinking about it i might just buy another Severn and use the lightest hardware i can get and see how well it performs.

Hi Jay

The problem is that you are looking at this from a modellers view. I met the guy from the RNLI who was setting this model up a few years ago. What he was after was a RTR for less than £50. I am aware that there have been quite a few that have had problems with the pod motors. My hope is that a few kids will enjoy playing with them and when they break will find the information from sites like this and the articles that have been published in the mags on how they can be improved and have a go at updating them. Then hopfully they will see a model kit and get that and have ago a building a boat and that way we get some youngsters intrested in our great hobby. The main thing is that if a youngster comes to you and says I have a broken RTR what can I do with it don't tell them to throw it in the bin but point them to the information about how to convert them. This might get them intrested and then you have a young modeller.

I see what your saying John, maybe i should of thought before my fingers hit the keys.

just a thought it would be a good idea if the rtr boats had hop-up upgrades that could be bought seperately, that way kids could upgrade as and when money allows them to. Bit like us with our bigger models we buy a kit and upgrade as we go along.

Without Jay & Astons' posts on this site and marine modeller mag, my 10 year old son and myself an addicted sail boat nut, would not have tried this upgrade, we just didn't have a clue. So on that note we say thanks to getting two generations into this!
We have enjoyed it so much we now intend a type 23 Frigate construction.

Im glad i could be of assistance and im sure the late Aston would be happy.
I started with my little Severn then went on to building my Schutze and havent looked back since.

dont know whats next on the table but i want it to be BIG.

Could you use a single 500 motor instead of two 380's as this will run on a 15A esc with no problem.

Shipmate60 · « **Reply #34 on:** February 28, 2008, 01:58:50 am »

Yes, but a graupner 400 should be enough power.

To run a scale boat you would need two shafts and so a gearbox is needed can anyone recommend one.

On of the problems with this severn is weight, the hull and superstructure take her almost to waterline.
The original electronics is a single unit, but when fitting her out with rudders, receiver and servos can make her rather deep.

Bob

explorer750 · « **Reply #38 on:** February 29, 2008, 05:14:35 pm »

Running one motor instead of two would help this.

Willit · « **Reply #39 on:** February 29, 2008, 11:40:23 pm »

this is all very interesting

I've linked it to my friend who has one of these as bought.

Its performence was sluggish to say the least, and it took me a while to figure out the steering on it (yes it really did confuse me!)

I know for a fact he won't do any of this stuff to it, but its good for him to know. He is a young enthusiast who might, just might, take up the challenge!

I've set him off on a project by giving him an old ABS hull I had knocking around. This had a shaft and prop as well as a rudder already fitted, and I myself fitted a deck, so he's off to a good start.

Any converted one of these boats to single screw?

Martin

Shipmate60 · « **Reply #41 on:** July 31, 2008, 03:59:27 pm »

Yes Martin, there are lots about.
There were at least 3 at Beale this year all single screw.

Bob

Martin (Admin) · « **Reply #42 on:** July 31, 2008, 07:50:22 pm »

Excellent! I ran mine yesterday at lunchtime and the fitted motors are ..... crap!

Anybody on here got a photos of the internals of their single screw conversion of the "Baby" Seven please?

Shipmate60 · « **Reply #43 on:** July 31, 2008, 07:54:07 pm »

Be a devil and go brushless!!!

That's a coincidence, I just dragged mine off the shelf and started to convert to single screw yesterday.

I'd be interested to see your build Martin, before I get to far with mine

Martin (Admin) · « **Reply #46 on:** October 11, 2008, 09:23:04 am »

Will do...... don't fit an M2 prop shaft, use a M4! :(

J.beazley · « **Reply #47 on:** October 11, 2008, 09:35:40 am »

Blimey this thread still going

Almost a year on and my little Severn is still going strong except my son uses it as more of a bath toy now more then anything ::)

kinversand · « **Reply #48 on:** May 07, 2010, 11:50:19 pm »

Martin,

Still interested in hearing about your baby severn conversion.

Also, why do you say not to use M3 shafts ?

Cheers

Dave

Shipmate60 · « **Reply #49 on:** May 09, 2010, 12:02:55 am »

You wont get a ready made prop to fit a 3mm shaft.
The Standard Shafts are 2 mm, 4mm. and 5mm for scale models.
Some odd sizes for IC boats.
