Here's the YouTube link to Dylan's song with poster cards:


Maybe make new cards, new words, new title "Aviation Homesick Blues"??? Or "Corn Stalk Blues"?

Nice picture of Frank and Robert.  It displays correctly when I click on it on my iPhone (it's just the thumbnail that is rotated). Kind of reminds me of Bob Dylan's song/film "Subterranean Homesick Blues" which is the one where he had these large poster cards with writing on them. Dylan kept on pulling out poster cards as the song went on. So this picture of you and piker is just the first slide?There's more to follow, right? The "Chica" sport racer was featured in the British magazine R/C Model Aeroplane for May 2017 (vol. 60, no. 5) as free plan give-away. I was lucky I guess when I bought it back in early June. Cheers, Richard B.

In May this year I went to Holland and had the privilege of meeting Ton van Munsteren, the designer of the RedEagle power glider.  It was the subject of our Build class 3 years ago.  Eight of us built one.

Ton was kind enough to let me fly two of his airplanes (RedEagle and Chica) and get some stick time in the Dutch sky.  In reply to my "Thank You" note, he asked me to say "HI" to Piker.  Mission completed last Wednesday when Piker showed up at training night.

Ton's Chica design will be one of the build class subjects when classes begin in the fall.

In my note to Ton, I wrote:"
He’s (Rob is) the good looking guy on the left.  The guy on the right is the one you should never again hand a transmitter to when he is in Holland.  :-)
 

Regards from Toronto.  Stay in touch.
 



...... and I have no idea how to correct the orientation of the photo.  It starts to straighten out after two beers. :D

General Discussion / Found: Damaged E-Flite Taylorcraft
« Last post by Richard_RC_Guy on Yesterday at 04:42:36 pm »
See attached photo. This E-Flite Taylorcraft was found in the Nurserie yard just west of the TEMAC parking lot and returned to the field by one of the employees on Sat. afternoon. I think it might belong to Bill who flies in the mornings. The esc, battery, and motor are in a separate bag. Propeller and prop shaft collar missing (maybe came off in flight?). I will bring the plane to the field Sunday morning around 10 am or so. If this looks like your airplane then send me a personal message on this forum. Regards, Richard B.

Well, we've received no feedback from Humber regarding our reasonable request to share the Claireville flying site in time for our float fly today (They know we had a date booked for today), so today's event is canceled.  I left it to the last minute in hopes to get some feedback from them.

I'll keep everyone updated regarding any further discussion.

General Discussion / Configuring INAV on a fixed wing
« Last post by Palkina on August 17, 2017, 09:02:49 pm »
    This topic is related to our experiences configuring and testing INAV 1.7.2 on a fixed wing. We expect to make it informative and useful for other members of the community.

Quick Background

INAV https://github.com/iNavFlight/inav/wiki is a fork of CleanFlight with a heavy focus upon GPS features for both airplanes and multirotor models.

iNav is being actively developed and currently supports RTH (Return To Home) with a predefined climb height, position hold, waypoints, "follow-me" and many more features.

Objective

To effectively re-use existing resources and electronics on an easy to fly plane.
  • Naze32 (10DOF) a control board with iNAV 1.7.2 version
  • GPS based on Ublox Neo M6N.
  • Radio receiver based on Lemon Rx DSMX Compatible PPM 8-Channel diversity antenna receiver
  • Orange DSMX DSM2 Compatible 2.4Ghz Transmitter Module V1.2 on FrSky Taranis X9D Plus Radio.
  • The Apprentice
Challenges

Radio
The radio has proven to be a point of failure.
  • The use of Spektrum receivers was discarded due to incompatibilities with other Lemon receivers.
  • All Spektrum receivers as well as the Lemon ones present a different pulse width ranges when compared to the ones used by FrySky modules. Approximately 1.0 to 2.0ms, compared to 1.1 to 1.9ms for Spektrum or similar. The initial test was made using the Spektrum receiver and the outcome was a run away
  • An improper configuration of the Taranis Radio may enable both Radio Transmitters, the original FrySky and the Orange DSMX DSM2 module

Flight Controller

  • Firmware upgrade
  • Sensor Calibration
  • Setting up endpoints for used channels
  • Configuration settings for Fixed Wing
  • Board alignment. Adjust to the leveled position of the plane in the air
  • Especial configuration to support RTH
  • Test preparation

Current status
  • Pass-through mode tested
  • Angle mode tested
  • Horizon mode tested
  • Navigation Altitude Hold (NAV ALTHOLD) tested.

Pending
  • Navigation Altitude Hold and Navigation Position Hold (NAV POSHOLD) combined.
  • Test Return To Home (RTH) flight mode
  • Configure an adaptive Failsafe
  • Test adaptive failsafe
  • Add and test FPV
  • Configure and test waypoints tasks
Lessons learned
  • Follow the KISS principle. Reduce complexity. Avoid mixing different radio links.
  • Keep focused on a single pit task and avoid distractions.
  • Make small changes and document.
  • Avoid rushing.
  • When things appear to be too easy, be aware. Take a step back and check and re-asses the potential points of failure.
  • Have a companion. Do not discard a second opinion and/or a way of assessing situations, tasks or outcomes.
  • Always find the root cause of failures and learn from past mistakes.
