If you are a foamie modeler or aspiring foamie modeler, this article provides good information on finishing foam airplanes with Silkspan or fiberglass, and Minwax Polycrylic. This report is about finishing foam airplanes with Silkspan or fiberglass and Minwax Polycrylic, and I hope that some of you will enjoy reading about results of my experiments. Minwax® Polycrylic® Protective Finish is a hard, crystal clear, extra fast-drying protective finish designed with the user in mind. The purpose of this experiment was to determine if a structure-less foam airframe could be achieved with fiberglass and Silkspan at an equivalent or lower weight than other construction methods.
Speaking of flight loads, I took the center section core bed and used it as a support for the completed wing and did a static load test.
If you take the wing as above and subtract out the foam weight, and then take the top and bottom surface area and divide that out, you get a covering weight with fiberglass reinforcement of 87 grams per square yard. This basically is saying that Minwax Polycrylic may be a safer, viable substitute for epoxy resin when fiberglassing raw polystyrene foam. Does anybody know where I can take some training in styrofoam sculpting using fiberglass and other product as hard coating?
Along with RC modifier and Madcroat and many other modellers not resident in the USA, I am unable to purchase Minwax Polycrylic.
I would like to provide some more of the Minwax quote, which indicates to me that it probably is a member of the waterbased polyurethane type. My first Radio Controlled fiberglass 42 inch model Lobster Boat based on classic Jonesport hull. The classic sleek powerful lines originating in Jonesport have been used on all manner of power boats to date.
Now in the 21st century what remains of these fine old lobster boats can be seen in th bone yards on the Maine Coast. I also built 17.5 inch plug for 32 foot Jonesport Lobster Boat to enable plank on rib construction. Battling Kit: Fast gun only kit includes the Hull Kit, Hardware Kit with ESC, Fast Gun Cannon System, Regulator, CO2 Tank, Pump, and Servos.
E-Fire Battle Kit: This is the same as the Battling Kit except that the traditional pneumatic buttons and other components have been replaced by electronic firing boards and solenoids.
For those looking to start up with a fast gun ship, the USS Brooklyn, USS Northampton, and DKM Lutzow are the most common rookie ships.
For the slightly more die-hard modelers out there, we are bringing back some of the pattern sets for wooden hulled ships.
I´*m interested in the product "Fiberglass RC Yacht Sailboat Thunder 1000mm", can you tel me what is the 2CH or more transmitter and receiver and the 4.8~6.0V receiver battery that is the best match to this model of sailboat? Can you tel me to, how many days would you need to delivered this items from a european werehouse.

This is with just a light sanding of the cores and straight Minwax Polycrylic right out of the can to apply the covering. The use of Minwax's Polycrylic coating in lieu of traditional dope or white glue as a cost effective, foam compatible covering material was shown to be effective.
Now, you still have to take into account the weight of filling the weave of the fiberglass, but Jim Ryan has already developed an excellent light weight method for doing just that. Is waterbased wood varnish able to be used as a substitute as minwax is not available in my country.I tried using a waterproofing membrane but that didnt work, the fibers dont sand down they just fluff up.
A few years back I did some research to find out what it was made of to get a substitute, and came to the conclusion that it was indeed, a water based polyurethane, and similar to several other local Australian products. The Hobbies & Crafts Zone offers selected adult hobbies, crafts, creative pastimes: model RR, model boats, kites, papier-mache, digital-scrapbooking.
Unable to locate any existing 1930's boats or photographs of their top sides the deck and cabin on my models are composites from boats at the Maine Maritime Museum and photographs of Jonesport hulled boats seen off the coast of Maine from 1960's to date. Driving through the area from Corea to Damariscotta, Maine you will sold wooden lobster boats passing away in driveways and fields.
Having read of model builders first making plugs to build plank on rib wooden models I built 32 inch plug for 32 foot Jonesport Lobster Boat. This typically includes a fiberglass hull, decks, prop shaft(s), rudder(s), styrene deck sections, foam and balsa superstructure pieces, scale plans, turret covers, and instructions. Please see our separate page for deck kits for more information, and order the kits from this current page.
The firing response times are typically better and after everything is waterproofed, the reliability is better. A little more difficult to build and operate are the HMS Invincible and SMS Moltke battlecruisers, but they are also more capable. These are large format pattern sets that have the ribs and keel (and many include superstructure) for making the ship by hand. All required items are installed, including mainsail winch, steering servo and all rigging, sail and hardware.
It is 100% handmade with FRP epoxy fiberglass and comes with a super smooth gel coat finish.
Import charges previously quoted are subject to change if you increase you maximum bid amount. Where I gouged it I did use some light weight spackle, but, as this is and experimental surface preparation, I wanted to press for a worst case scenario. Then you can patch and paste and lay down strips, and then re-enforcing pieces as required.


In addition, it is actually kind of fun as there is no odor and it just washes right off your hands with water. MadCroat i tried the varnish on just the plane alone and it has a relly nice finish but reacts with common spray paint to make bubbles. George pulled several glass hull for me and provided hulls to model builders here in Massachusetts. Then a layer of resin jel-coat is applied, allowed to cure, followed by layer of resin impregnated fiberglass. All you need to do is add your own 2CH or more radio system and battery!Boat hull is based entirely on an ocean going racing yacht and moulded in fibreglass with a perfect gelcoat and enamel painted finish.Don't be mistaken in thinking these boats are slow and boring.
If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
What's that track playing btw?b1heqh54: Thank you for taking the time to comment - I'm always delighted to hear that someone else out there has an interest in this sort of thing! Of special note is I used 20% thinned Polycrylic to cover the fuselage in an attempt to save some weight. When fiberglass is cured the plug is removed by pulling the bow of the plug from the new female mold.To manufacture hulls the process is reversed.
Most ships will also require a radio system, batteries, bilge pump, CO2 and cannon system, and running hardware to be combat-ready.
This tape is especially for cutting up your beautiful hulls, the width is the perfect size for marking off your rib widths.
In a stiff breeze they can be extremely quick and perform turns rapidly, proving to be very exciting.
This torsional rigidly was achieved to a greater extent than had at first been anticipated. It should be noted that the Polycrylic does not achieve full hardness for 2 to 3 days, so give it some time before applying flight loads. If I was to change any one thing in the lay-up of this wing, it would be to apply one more layer of glass cloth to the top, center third of the wing before applying the Silkspan. Still, my opinion is that this wing, as is, will survive any and all flight loads a speed 400 could place on it. Interestingly enough, the slight bowing is easily overcome with hinge tape and a fine hinge-line is produced. Until then I just cannot justify the cost of shiping one out of China (very costly due to being oversized package).
