Dremel 4300 Rotary Tool

Model Airplane News - - PRODUCT WATCH -

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
