RTR Severn Class Lifeboat

I just bought the 'ready to run' Graupner Severn Class Lifeboat. I'm pretty sure it is the same as the one offered in the UK.

I would like to fit 'real' R/C to this model. I have already done this with a couple of the low cost toy category boats currently available and have been very pleased with the results. Unfortunately this does not appear to be a simple task on the lifeboat as there is only a small access hatch for the batteries

Does anybody know how to remove the superstructure ? I have done some exploratory prods with a screwdriver and it seems that the top is only clipped on, not glued. I tried a little force, but chickened out to avoid causing damage.

Any advice would be very welcome.

Thanks

Chris P

Hi

The superstructure is screwed on from underneath, you have to remove the deck first.

There is a lot of information on the Mayhem site, have a look here to get some ideas.

Go to the top of the class and assume hero status.

That's exactly what I needed.

Many, many thanks.

I didn't realize that Graupner was the manufacturer of that little model.

Is it propellers and rudders or is it dual propeller with differential steering?

Well, yes and no; Graupner has it made in China and is the distributor.
It has the 'dreaded' tanksteering if I'm informed correctly.

Glad this popped up! Please keep us updated on progress. I am very interested in how the project goes togerther.

I was considering trying to modify one this winter but RC SCALE MODELS here in the US ran out of stock and I couldn't afford the hefty bill to get one special ordered. Thought about having one sent over from the UK as well but.....plans change

Ghost - have you converted a Severn? What type of glue/goop/adhesive would one use on a plastic hull to secure shaft tubes and rudders?

If I'm not mistaken, the UK model has been out for a couple of years and the Graupner model is fairly new. I assumed that Graupner was not the instigator of the model, but maybe I'm wrong.
Ghost - I don't know the term 'pod drive',but I can confirm that the rpm's change on one side when the stick is operated.

I have read the Mayhem site a few times and taken a good look at the model, but I'm not sure how to remove the deck. Is it glued on ? Does anyone know ? I just don't want to break anything.

On a different note - one person's comment on Youtube about this model was that his model sank. When you see the size of the gap between the deck and superstructure it's not surprising. So there's a real interest in doing the job properly.

I'm in similar circumstances. All I really need is for someone to tell me how to remove the deck and I'll work out the rest myself. In any case, I never did a kit bash in the past the same as anyone else.

nope, however to secure the various tubes that pierce the hull, treat it like a regular abs kit and use regular epoxy glue, (eg araldite).

I have a gutted NQC 'Pelican' that had the same pod drive and ran on 6 penlights, quite high up in the hull, causing an 'adventurous' CoG, making it sway from side to side.
I replaced the penlights by a 6V SLA deep down in the hull, which made for a much smoother ride.
Eventually the sealing on the pods started to leak badly and the motors rusted solid, I pried them out , but they'll never run as before...

The deck was fixed witn numerous screws, hidden under rubber stops and (how devious) deckfittings, I nearly broke the thing trying to find the last few.

So I'd try to remove all deckfittings. stancions, deck housing to locate the screws, you'll get there eventually.

Question from my end: what did you use as glue to keep the new propshafts in place, my hull is the type of plastic, nothing I have will stick to...
Very frustrating, as I have the parts for a refit with 'normal' radio gear at the ready.

Regards, Jan.

The deck is screwed down, the screws are under the black plugs on the deck. In the pictures one of them is under your screwdriver. The deck is sealed with a large o-ring which fits all round the top of the hull, so be careful when you remove deck.

I can dig out some pictures if it helps

You bet it would !!!!!

As there seems to be some interest, I would be quite happy to go ahead and report on my build progress.

Yes sir, way to go !!!

I just bashed a toy cabin cruiser and used nothing but 5 minute epoxy.

OK - I removed the five rubber plugs and the corresponding screws underneath them and the deck came off a treat. I found the mentioned seal / O-Ring and treated it with due respect.

I now understand what is meant by the term 'pod drive'. Yes, it has pod motors.
