Re unwanted motion, no problem if OP supports model from multiple attachment points. A 1/72 scale model spinning at takeoff RPM and blade pitch will not even taxi much less lift unless the ambient air density is also scaled down. One of Tamiya’s 1/48 motorized series taxi’d under its own untethered battery power. To do so, the prop spun unrealistically fast and other considerations were required. If you are truly intent on motorizing with remote control come hail or high water, it can be done. Some liberties may be required. For example, since the plane hangs above eye level hide a thin

The big auction site has pager motors for about $1 a piece. Some come without the weight. Otherwise search the web for how to remove the eccentric (weight) from a pager motor and you will see many how-to articles. Readily available motors in hobbyist quantities will come in metric diameters like 4mm, 5mm, 6mm, etc. So study your nacelle. The shafts are also metric and for the size motor you need it will probably be between 0.6mm to 1.0mm. Experiment drilling into some scrap sprue to determine if a non-metric or numbered drill bit will give you a nice press-fit to the prop. I cannot over-emphas

The vibration motor extracted from a Gillette Fusion Power razor fits nicely in a Bronco 1/48 Predator. Every few months these are FREE after rebate or Sunday newspaper coupon at drugstores. Like vibrating motors from cellphones, just remove the off-centered weight eccentric (tiny metal part in photo) from the motor shaft. With the single AAA 1.5 Volt battery in the razor, the prop spins way too fast. To your point, it seems as if something is going to fall apart. Some Tamiya motorized prop-action kits provide a diode (the tiny black part on red wire in photo) which reduces the voltage to

Look for surface-mount-technology or SMT LEDs as used by Atlant. These are specified by LxW dimensions. If in the US, search for 0402, 0603, or 0805 sizes which correspond to .04†x .02â€, .06†x .03â€, etc. In general, LEDs of different colors operate at different voltages so you typically need to use resistors to operate different LEDs from a common battery voltage. If you search on “LED resistor calculator†you will find on-line tutorials explaining this. SMT LEDs come in different heights so you might be able find one that works for logo lights assuming they go in the rear horizont

Perhaps Nd magnets could also work for wall-mounting by attaching an Nd magnet to the end of the wire or arm coming from the wall. This way you could take down the plane from wall mount and put it on a plaque-mount pole to take to work or a show. Again, the woo-hoo is no drilling into the a/c, but does require fore-thought to insert a magnet into a/c before sealing fuselage. I'd guess a pair of Nd magnets for a typical 1/48 single-engine would be about a dollar. Very cool. I'd be interested in anything more you can share about your project! I've always thought the holy grail of in-flight

Neodymium (Nd) magnet discs - the ones with the silver-colored (nickel) plating - available at craft stores or online. Install one disc inside fuselage, the other on the tip of the pole. No drilling, no protrusions, invisible, etc. Nd magnets are incredibly strong but not so strong that you can't pull the a/c off the pole for transport. Since the attraction force of two disc magnets does not change with angle, this technique answers the rotation problem of telescoping rod-tube typically solved by keyed or square rod-tubes. That is, you can re-position the a/c after the fact.

I saw it on the Greek modeling site a while back but they now seem to require login so the direct link doesn't seem to work. I found the following Google copy of the thread which worked for me: cached google link Google also came up with the following link that has some pix and a video of his VFS P-47 in-action so to speak: click on the movie projector icon at bottom of page

In case you haven't seen this, I thought your fellow countryman Brian Boot did a fine job on his VFS P-47D25. Somewhere in there is an electric motor that can spin the prop. Here's a linked photo from his build thread on the Hellenic modeling site.

http://www.loxx-berlin.com/en/en_galerie.html You don't need to understand German to appreciate what they've done. If you hunt the site, they have videos of aircraft taxi'ing into position, accelerating down the runway and taking off (you have to see it to believe it) and emergency vehicles driving across the tarmac. Mr. Obama's new ride is one of their models...

Item 170285671907 on eBay right now is purportedly a B-17 IFF control box. As I understand it, pressing the KEYING button flashes any colored light set to the KEY or down position. So I suppose even on the hardstand, artistic license might allow one or more of these lamps to blink as the crew tested their equipment...

Lens is nice because it's large and rimless unlike most round light magnifier lamps where the circular bulb frame is in the way. The lights are dim to the point of being useless. I replaced the OOB LEDs with hi-powered LEDs and now its plenty bright but it was a complicated undertaking. OTOH I also use Helping Hands magnifiers when the base is not in the way - $3 at Harbor Freight.

A relay is often used to switch AC line voltages - such as turning on a lamp as in this ORP12 circuit which is the first one from Google: http://www.8051projects.info/files/dark_switch.gif But since you are switching relatively low DC currents, you can put your LEDs in place of the relay in the above circuit. For example, in the above circuit, the 9V supply is more than enough to drive a red, green, and white LED connected in series to drive your Navigation lights. Presumably you have external power since replacing batteries in 1/72 can be a challenge as the circuit is drawing power 24/7 (e

Had same problem. Trumpeter customer service sent these - was missing page 1 and 2 but I was happy to get any response at all! HTH

Try: link or go to June 22 on the ARC homepage and click on the link. WRT plexiglass/acrylic rods, I've always wondered if you could simulate a stream of sci-fi photon torpedoes by sanding or masking segments of a bright white illuminated rod - might also apply to simulating earthly tracer bullets if orange is used.
