SSL Errors fixed and new Logbooks

SSL Errors
The SSL errors you may have been seeing are now fixed.   This was also preventing the mobile apps from synching.   They work again as well.   Thanks for your patience.

Logbooks
A newer feature to the site are the community and personal logbooks.   These present flights as if they were in an actual book.  Click on the links to see the respective logbooks.

Calm air and blue skies.

Plane Spotter

My new Android app Plane Spotter is now live in the Google Play Store.

It was born at the Wings and Warbirds over Port Clinton airshow.  I was trying to learn about a plane there and had great trouble entering the FAA registration number into the FAA website.

Wit the app you can either type in the number or speak it (using the phonetic or normal alphabet) and then see the results.

Check it out – it is free!

Cubic Wing Loading and Flight Performance Calculations

I just came across some great articles that explain cubic wing loading and different factors that affect the plane’s flying characterisics.   These are well worth checking out:

How much dihedral?

How much dihedral does a model plane need (for RC)?   I came across this post on RC Groups from Pat Tritle explaining how much he uses in his designs:

FWIW, Over the years in dealing with 3 ch (Rudder, Elevator & Throttle) airplanes, I have discovered a pretty general rule of thumb. On a typical high wing cabin or parasol type airplane airplane, 4 1/2 deg. dihedral works very well. Entering the turn with as little as 3 1/2 is do-able, but getting out of the turn is another story. On a shoulder wing, you can get away with 6 or 7 degrees, while low wings need upwards of 8 -10 deg.
Now, “dihedral effect” is also a factor. A high wing without dihedral will offer the efect of 2 – 3 degrees, where a shoulder wing will act like 0 degrees. Low wings, on the other hand, at 0 degrees will actually give the efect of “anhedral” and become somewhat unstable, requiring 2 – 3 degrees of dihedral to achieve a 0 dihedral efect. Wing sweep also plays a part, but that’s another story altogether.
With that, it’s easier to understand why low wing models need more dihedral to turn using only the rudder. Biplanes, for reasons unknown to me, tend to make their own rules. All 3 of my 42″ span Wright flyers, the ’03, ’09, and 1910 Model “B”, turn just fine on the rudder alone with only 3/8″ of dihedral per tip — now that’s something to think about!

Online Free RC Books

Most of you are probably familiar with Outerzone as a source of RC model plans, but did you know they have a sister site called RC Library that has many free RC Books and magazines that are out of print?

Check it out!

Looping

Dave Scott has a new column up on the AMA’s Model Aviation site called Mastering the Loop.   He goes into great detail explaining how to fly a loop in a controlled, precise, and round (!) manner.  While yanking that rudder will loop the plane, it can be a whole lot more precise.  Check it out…

Free Online WW1 Aviation Class

Future learn and the BBC are sponsoring a free online WW1 Aviation class starting February 9th:

We’ll look at the innovations that turned the aeroplane into a machine of war and how British factories developed to supply the Western Front with aircraft and ammunition. We’ll examine how the aeroplane became commercially viable, with passenger and mail routes starting to appear, and how the government tried – and failed – to regulate the aviation industry.

I’m signed up. See you there?

 

 

Introduction to Electric RC Flying

Just found this great introduction to electric motors in RC over at the Watt Flyer Forum.   I’ve been flying electric for years and still found new information.

Mobile RC Flight Logging Application

I’m pleased to show you the first release of the mobile application for logging RC flights at the field:

Logging a (very long) flight on Android.

This is currently a HTML 5 offline web application.  An Android application will be in the Play Store soon.

Full details and links to the app are on the RC Flug Log Mobile Apps Page.

Scale!

RC Flug-Log now has scale:
