Miraco interconnect – company spotlight

I get e-mails all the time for different products generated likely from mailing list. However this company and service caught my eye. Miraco makes custom and COTS electrical signal and power assemblies and circuits for different needs and industries.

https://www.miracoinc.com

sales@miracoinc.com

They are located in Manchester New Hampshire USA 🇺🇸

It’s great to see a domestic source that produces custom electrical components particularly on the east coast.

If your in the market for such components I would check them out.

Sourcing USA – Web site share

I came across  www.sourcingusa.com For domestic search for suppliers with in America. One competitive edge that foreign suppliers have had for the past 2 decades is the ease of networking and making connections with buyers ever since the rise of the Internet. The other advantage is these suppliers are willing to work with smaller buyers & low Minimum order Quantity (MOQ). Many of these smaller companies that started small ended up bringing their suppliers with them on the ride up to becoming mega companies.

Hopefully this resource can aid in your next sourcing need where you can enjoy:

  • No Tariffs.
  • No Customs.
  • Reduced Shipping times & Cost.
  • Ease of factory visits.
  • Breaking archaic sourcing dogma.
  • Made in the USA branding.

Fly Baby – Aircraft of the Month

The Fly Baby is a very popular Home Built aircraft with a good amount of RC options as well.

It first flew in 1962 and was designed by Boeing historian Peter M Bowers.

The Fly Baby can also be converted into a Biplane called the Bi-Baby.

http://www.bowersflybaby.com/ is a great unofficial Fly Baby web site

https://eaa.org/eaa/aircraft-building/kits-and-plans/d—g/fly-baby

Is a great resource, If you are an EAA member there are Sport Aviation articles ranging from 1962 – 2005 plus a pdf download of the 74 paged Building the wood airplane part of EAA’s “HOW-TO” series from way back.

 

Now for some RC options, Outerzone has a bunch, here are some that look quite workable today with electric power.

K-12 STEM Links

Some good news with our current world, A middle school teacher contacted me letting me know the value that she & her students are getting out of the web site while studying from home. She let me know about an interesting WWII Car, Airplane and Tank article on:

https://www.titlemax.com/articles/cars-tanks-airplanes-of-wwii/

There are 3 main very high value community based organizations (CBO) I recommend for any K-12 STEM program. These 3 are also where I got my start in middle school in the early 90’s

 

EAA Experimental Aircraft Association  

Young Eagles:

https://www.eaa.org/eaa/youth/free-ye-flights

Find a Local Chapters:

https://www.eaa.org/eaa/eaa-chapters/find-an-eaa-chapter

 

The 3 largest airshows in the US are (in normal times):

Airventure in Oshkosh Wisconsin put on by the EAA (July / August)

https://www.eaa.org/airventure

Sun-N-Fun in Lake Land Florida (March / April)

https://flysnf.org/

Copper State in Buckeye Arizona (usually early in the year)

https://www.copperstate.org/

 

AMA Academy of Model Aeronautics

very accessible and low cost, a good foundation to learn about aviation & turn it into a life long passion.

https://www.modelaircraft.org/

http://amaflightschool.org/programs

Flite Test is another CBO that has strong low cost / easy access RC aircraft & Multi Rotors.

https://www.flitetest.com/

 

Model Rockets:

 

Tripoli Rocketry Association, Inc. the main organization that puts together model rocket launches, works with FAA & local government to make sure everything is good to go. They focus on high power rockets but they also have the smaller ones at the launches as well.  http://www.tripoli.org/

Estes Rockets a supplier of A-E impulse model rockets https://estesrockets.com/

 

Hope this helps with your schools programs, feel free to share with other educators.

Sphinx Moth natures inspiration for flight

Fueling up at a gas station today next to the car was one of my favorite insects, a Sphinx Moth, also known as a hawk moth

https://en.m.wikipedia.org/wiki/Sphingidae

https://www.butterfliesandmoths.org/species/Eumorpha-fasciatus

It’s black and sand gold color pattern is quite striking and the delta planform while resting reminds me of some delta wing RC aircraft I’ve designed in college (green) and when I worked for piper (blue)

of course in flight the Sphinx is no different than any other Moth or butterfly 🦋 with a tandem / low sweep planform

Custom multi rotor build web site.

If you have ever been to a multi rotor race (some times called a heat) there is a vast array of custom built racing drones all with there own selection of components. The top competitors and YouTube freestyle stars like Skitzo and Mr Steel are almost fully custom builds and not turn key “consumer grade” machines

Usually pilots are in full competition mode and deciphering what makes up a given machine can be a challenge.

I found the Rotor Builds web site on the rotor riot Facebook page.

https://rotorbuilds.com/builds

On this web site multiple custom multi rotor builds are listed all with component list and links where you can buy the components.

While my old trusty and still flying ZMR 250 is still flying it’s 2014 technology. Like “dog years” this is down right medieval level.

I found the rotor builds web site to be quite informative
