Ten years ago, I bought out a Hobby Shop which carried a very good stock of Graupner and Robie kits, hardware and fittings.
I havevsold most of the kits, but still carry many Robie hardware items, along with a very extensive Graupner and Robie inventory of fittings.
If anyone is interested, message me with the items you need.

Sorry to hear you are bowing out, hope you stay to offer advice and comment too.
I know the feeling, have been building models for over 50 years, and still very active in building for commissions, layingbup fiberglass hulls, and selling and shipping model fittings and equipment through my model shop.
I know my wife says " What are you going to do with all this stuff??" Or "What am I going to do with all your stuff??" I'm not quite ready to even think of this yet, still having too much fun in my retirement.
Cheers

Not in total defense of Dean's, who have been in business for many years, however once z parcel leaves their door, it is out of their control for delivery have noticed many times where simple deliveries get routed all over the country because of mail processing and travel scheduling.
After you would receive your refund, would you be returning the plans back to Dean's on your postage coin? I know many time when I am shipping parts or plans, often it takes two weeks or longer, here in Canada.
My thoughts would be to wait at least one month, hoping it does arrive for you.
Cheers

If it is your intention to simply use the Gelcoat as a hull finish, yes you can brush it on, then sand to your perfect finish.
My preferred method though, would be to fibreglass the bare wood hull with poly resin and at least one layer of 4oz or lighter, first, to put the strength into the hull, then finish with gelcoat.

I do use Styrene often in my scratch builds, and I have also built three Krick cranes from printed sheet styrene.
I tried being a 'purist' and using solvent glues, but my best results were in using good medium set(15 sec.) CA GLUE..

Most of my model fishing boats are based on inshore and mid-shore Canadian lobster boats, which I build either 1:18 or 1:12 scale, and many of them, the client wants full R/C.
Being large scale, means the wheelhouse windows are large enough to warrant detailing the interiors.
I have bought some figures to scale and I do the interiors also.
- I'm including couple photos of interiors, plus working crewman near the gear

The only pre-requisite for LEDs is to ensure you have all + Positive wires together, and all

๐ Motors
5 months ago by
๐จ๐ฆ GregHiltz (

Hi,
You can have your motors counter-rotating
( recommended ), and also go one step further and have two ESC's, one per motor, allowing you to have great maneuvering, like turning in a very tight circle, and crabbing sideways.
Just ensure you have Right and Left pitch props.
For motors, I would suggest Mabuchi type High Torque 775 motors for the Dauntless. I stock them turning 6000 rpm at 12volt.

๐ Brushed motor capacitors

Ion, if you are still using the older (AM or FM Crystal) type R/C sets, which always were prone to wayward RF glitches, then yes, using 2ร .047mf ceramic capacitors do help if you are getting glitches in the servo action caused by the brushed motors.
I havevfound with the newer technology of the 2.4 mhz systems, they bind and lock the Tx and Rx together very well, and with all the systems I have geared up, find no glitches at all.

๐ Fiberglass boat hull
6 months ago by

I'm new to boat building and have reached a point where I'm ready to glass the hull. Questions (after reading numerous articles):what kind of resin, epoxy is best to use? I'll need some time to set and smooth.
I used to build model planes with silk wing covering (years ago) but very little of the material I use to use is still on the market. I go to hobby shops and it seems building is becoming a lost art, everything is foam!
Ant input would be helpfull.

For years I had used white Lithium grease in my ShaftTubes, but forcthe last 10 years, when I build ShaftTubes, I also make a vertical oil tube at the front of the tube.
I use SAE 80-90 Gear Lube , 15 to 20 drops in the oil tube per year.
It is heavy enough to not drip from the tail.

Your other option, so as to not leave you stranded out in the water, is tobuse Automotive type small circuit breaker, which will re-set after they do trip, usually in20 to 30 seconds.

๐ Fuse position Rttl installation mod
6 months ago by

My opinion, is to protect the ESC.
I always put the fuse between the positive motor lead and the ESC, since it is usually the motor which is the source of the amperage overload.

S, joining both motors to the one set of ESC leads will work, but always double check the motors combined Amperage drar, not to exceed the Fuse rating or ESC capacity.

Reversing motor rotation is simply swap (reverse) to motor leads on one motor.
Bear in mind, if the boat had both propellors pitched (handed) left or right, you will now have one motor wanting to send you backwards and one forward.
You will need one Right hand pitch, and one Left hand pitch, commonly available from Prop Shop, or any good model boat shop.

๐ Speed controller
8 months ago by
๐จ๐ฆ GregHiltz (
Chief Petty Officer 2nd Class)
Flag
Over here in Canada, we referred those rheostat friction controllers as Bob's Boards.
They are simple, resistance type controllers, very inefficient, as voltage not used(partial throttle) gets burned off in resistance.
Any of the modern ESCs are digital, and the circuitry allows any unused voltage to be returned back to the battery.
The price of the newer Controllers and reliability makes them the way to go in my humble opinion.

Simy put, if both wires are same colour, if they don't work one direction, reverse your wires.
Some LEDs have one wire longer than the other.- longer lead is often the pos.
The wires can usually be stripped with a thumbnail or small blade.
I solder the leads, then cover with small heat shrink tubing.

๐ What is this?????

๐จ๐ฆ GregHiltz (

Very old setup, and my humble opinion is to trash it all, and buy a new ESC and R/C system.
Today's new systems are very simple, have sync-binding features which prevent glitches from wayward RF, and the new ESCs do not rely on friction to regulate the voltage/speed.
Personally, I use and sell the Flysky brand R/C gear, and have had no troubles at all.

Ey are great connectors, and I use them very frequently.
The key is to use a high powered soldering gun, minimum 100 watt, not the little 35-40watt pencil soldering units.
I always use a little solder flux in the connector socket and on the wire, then load up your soldering tip with solder, stick your wire into the wire socket then hit the joint with the solder.

Very well built and executed model.
The Nautical Commander was the 'Dream System' in the 90's.
No doubt many mechanical switchery could be replaces with electronic modules. I cannot see the ESCs, and they possibly could go modern digital units if necessary.
I see the Pittman motors, they always were very efficient, and were the standard with Dumas kits.
I dare say your batteries will be 'Kaput', but could easily be replaced with a pair of 7.2v NiMh packs with a 'Y' cable.
Please keep us posted on your progress.
