Dremel 4300 Rotary Tool
With its universal three-jaw chuck, the Dremel 4300 doesn’t require additional hand tools to change tool bits, so it’s compatible with all Dremel attachments and accessories. It also features an all-new swivel light, which provides illumination for tight and hard-to-reach areas where you might work. The Standard Edition includes five attachments and a great selection of 40 Dremel accessories, with a molded storage case that holds the tool, all the attachments, and accessories. The 4300 is also available in a Platinum Edition, which includes eight attachments as well as the Flex Shaft attachment and 64 Dremel accessories. Its large storage case is equipped with metal latches, reinforced corners, and a foam-lined drawer.
The Standard 4300 tool includes a variety of useful grinding bits, sanding drums, polishing pads, and EZ Lock cutting discs, all of which are ideal for most RC modeling tasks. A noticeable feature of the 4300 is a built-in variable speed and electronic feedback circuit that helps keep the motor running at peak performance. When you switch on the tool, you can feel the torque ramp up, which minimizes stress on the bearings and brushes. The adjustable speed dial and separate on/off switch make using the tool for various jobs highly intuitive. It is easy to dial in the exact rpm you need for a given task.
I’ve been using Dremel products for decades, and the 4300 is the best yet. I highly recommend this new rotary tool for any modelbuilding task. The Dremel 4300 is available online and at select retail locations for $119.99 (Standard Edition) and $199.99 (Platinum Edition).—Gerry Yarrish dremel.com
Fliteskin Fiberglass Sheeting
When it comes to covering and finishing scale model airplanes, a big part of the process is producing a smooth, blemish-free surface for the base of your paint scheme. For World War II fighters and other sheeted airplanes, you do this by applying fiberglass cloth and resin, then filling, priming, and sanding until you produce a smooth finish. But there is also another, much easier way—especially when you are duplicating sheet-metal surfaces on fabric-covered airplanes.
Fliteskin is a fiberglass sheet material with a built-in smooth finish. For many professional modelers and competitors, Fliteskin has become the standard for airplane covering whenever a realistic scale finishing is required because it saves countless hours of sanding and priming work. I decided to use 0.010-inch Fliteskin when I was covering and finishing my
Balsa USA Fokker Triplane, as I found it to be the closest representation of the real sheet-metal finish on the full-size aircraft. I have tried sheet aluminum and thin metal flashing, but these did not work as well and were heavier than Fliteskin. Plus, Fliteskin is translucent, so you can see through it and mark it exactly as you need it for cutting to size. Once cut to the shape you want, just screw it in place (along with some glue on the underside) and it’s ready for priming, depending on the paint you are using.
The material is flexible, easily going around curved surfaces, and it is very strong for ding resistance. The unpainted material is fuel- and weatherproof and can be primed and painted without any surface prep. I did clean the surface with some denatured alcohol before painting, but no scuffing or sanding was required. Fliteskin is available in 36 x 48-inch and 36 x 24-inch sheets in 0.007 and 0.010 thicknesses.
Fliteskin can also be used to line cockpit interiors, wheel wells, and channels in wings, and can be glued directly to built-up and foam wing and tail surface structures in place of wood sheeting. This saves both time and weight, and also allows you to form very thin yet strong trailing edges that won’t chip or dent. Because you can see through the skin, you can precisely cut it out when placing it over plans, ribs, and formers. Priced from $25.50 to
$48.50 depending on size and thickness, Fliteskin has a lot to offer the scale modeler.—Gerry Yarrish fliteskin.com
