General Discussion / LiPo Factory
« Last post by Deerslayer on September 17, 2018, 08:41:39 AM »
I bet that most of us are unaware of how KiPos are manufactured. I found this tour of a LiPo factory to be very informative. (It takes awhile to get to the actual manufacturing process.)

And, if you liked that one, here is one showing how propellers are made - by the millions! This reminds me of my 4th Year Engineering project (1969/70), which involved resurrecting a dormant injection moulding machine and trying to get a computer model of the process working. At that time, prior to the common use of CNC machines, the intense design, development and manual creation of the dies meant that injection moulding was usually only economically practical for production of 150,000 or more units. Tool and Die Makers were at the top of the pyramid in plastics manufacturing operations.

Upcoming Events at KRCM and elsewhere / Deseronto Float Fly and Swap Meet - October 7
« Last post by Deerslayer on September 16, 2018, 07:40:57 PM »
Sunday, October 7 will be the next great Float Fly and Swap Meet at Deseronto.

There will be food available!

If you have stuff to sell, bring it out. There is no charge and unlimited space to set up.

Bring some cash, as there will some good stuff for sale. Some of us will have floats, planes, engines, etc. on display!

There will be a  50/50 draw!

The large field is quite suitable to fly small foamies only (so hand launching is likely essential).

FPV at KRCM / Re: FPV Video - 9 SEP 2018

That was a great video Gary.  The information displayed was excellent.  To bad we can’t figure how to turn off the foxeer OSD. The vector certainly puts the old system to shame. Your added commentary was well done.

FPV at KRCM / FPV Video - 9 SEP 2018
« Last post by Deerslayer on September 11, 2018, 09:47:11 AM »
This short video shows flying FPV with the assistance of the Eagle Tree Vector flight controller/stablizer.

https://youtu.be/PD9J8yYc-B4

Discussion:

There are a great many parameters, modes and display options available with the Vector. I have this particular aircraft set up to use five Vector Modes. plus OFF. Depending upon which DX9 Flight Mode is enabled, the desired Vector Mode is then selected via one of two switches on the transmitter. In Flight Mode 1, Switch E selects OFF, GYRO or LOITER; in Flight Mode 2, Switch F selects OFF, RTH TEST or WAYPOINT. Of course, Bitchin' Betty announces switch positions, in addition to the OSD presenting the actual Vector Mode.

 Return To Home (RTH) will automatically be triggered if the Lemon receiver goes into Failsafe due to a loss of signal. I have tested this on several occasions by turning off the DX9; the aircraft climbs or descends to the pre-programmed altitude and returns to Home, then proceeds to climb or descend to a pre-selected altitude and circles about Home until .. forever, or it regains signal or the battery runs down!

RTH is interesting. The Vector only sees Receiver PCM outputs, it is unaware of the 2.4 GHz reception. How does it figure out that we have lost control contact? The receiver has been set such that, upon loss of signal, it drives the Throttle channel down to -130% or such. This low value cannot occur in normal flight, since the Throttle Travel is +100%,-100% and Trim is disabled (=0), as with all my electric aircraft. So the Vector goes into RTH. Much fun the first time, as you switch off the transmitter and watch as the aircraft changes direction and heads back Home, circles around like a pet dawg and waits for you to turn the box back on! It works!

In Loiter Mode, the aircraft immediately enters a pre-set circle of approximately 60 foot radius and maintains altitude, until it is released from Loiter, or ... well, you know ...

The OSD (On Screen Display) has many options, involving which items can be displayed and where on the screen each will appear. You can even set it up to present alternate displays during flight. I am still playing around with different combinations and appearances.

There are 2D and 3D Modes, with or without Heading Hold. I have used them but neither are currently set up for this plane. I use OFF, GYRO, LOITER, RTH Test and WAYPOINT, with the latter being to perform the stored Mission.

Apart from the 2 DX9 Flight Modes, each of which enables a specif switch to associated control Vector Modes and perhaps some other Mixes, I have the TOGA (Take Off / Go Around) Mode.

In TOGA, the Vector can be either OFF or in GYRO Mode, while the Throttle Stick is now used to manipulate Flaperons/Spoilerons (and a highly exponential Throttle Curve in its lower travel. Sort of a "partial Crow", as the plane has no flaps. Being a floater, this enables steep climbouts and high angle approaches for excellent short field performance, especially in rough conditions.

At any time, I can Tilt the camera via a transmitter Knob (not particularly useful) or detach the Rudder control and use the Rudder Stick movement to Pan the camera.

This aircraft uses 10 Mixes and 3 Flight Modes on the DX9, plus 5 Vector Modes. Lots of neat stuff!

The camera is a Foxeer Monster, with something like a 135 degree field of view. As a result, there is a major fisheye effect. Also, everything looks more distant and smaller than normal. This is typical of FPV cameras. You just have to get used to it.

The camera feed is merged with the Vector display and the combined video is transmitted at 5.8 GHz. The range is much less than the 2.4 GHz used by our radio control systems, and has no error correction. this video was recorded by the ground station - an Eachine 7 inch screen receiver with internal DVR. As such, the quality is fairly low, starting at 750p and degrading during transmission. It gets particularly poor if the aircraft is directly above the receiver or if it approaches cloud or the increasingly humid air that exists well below cloudbase.


The various aspects of the Vector can be set up via USB connection to a PC, using ET-supplied software. One can also download and display flight logs, even combining the GPS traces into Google earth. As well, you can plan an install a GPS-based mission with various Waypoints, cruising altitudes, specific actions to be taken at various Waypoints, and RTH. I have done this, and it is an amazing capability. Given a suitable camera, such as Mobius, that can record internally at high definition, pointed at a suitable angle, this can be an excellent mapper or searcher. Fly a grid, analyze the video in real time or later. My next FPV-specific plane will be set up with the FPV camera for piloting plus the Mobius for high quality recording. I may do that with the Penguin, as soon as I  "get around to it"!


Some production notes:

I am a fan of cheap and free stuff!

After much experimenting, I have discovered an excellent Open Source video editor called OpenShot.

I use VLC, a free video viewer that has some additional capabilities. One is the ability to repair and/or convert some video raw feeds. The Eachine DVP, like many cameras and other video devices, can create a .AVI file. Frequently, VLC sees a problem with a source file and unlike MovieMaker or many other programs, it doesn't just give up; rather, it fixes up the file, if possible and you can subsequently view it and Export as .MP4 file which OpenShot likes.

The audio was created by Audacity, a superb Open Source audio capturing/editing system. I record, edit and then Export the audio as a .WAV file which OpenShot can integrate with the video track.

General Discussion / Debbie Gary - an Airshow Super Star
« Last post by Deerslayer on September 08, 2018, 07:09:03 PM »
I came across a reference to Debbie Gary recently. I have a very minor connection to her and thought I might mention a bit about her.

Who is she? A great lady, a top notch airshow performer and, for a brief time, one of my gliding instructors!

Back in 1972, as I was learning to fly gliders, a friend and I read an article in Flying magazine about Sugarbush Soaring over in Vermont and its two female instructers - Debbie Gary and Holly McAllister. Well, this was too interesting to pass up, so we took a week of vacation, hopped in my Datsun 240Z and set out. I was not yet at solo stage, Ray had been flying solo for about a year.  We had a great time, lots of flying,
 I soloed on flight #23 (my 6th one down there). I even managed to get a flight in the mountain wave later in the week. I can remember the entire week like it was yesterday.

I had a couple of flights with Debbie Gary. We watched her giving aerobatic instruction in a Citabria on several occasions, as well as flying a Pitts Special. An amazing talent!

Fast forward to the big airshow in Kingston in 1990. One of the performances was by the Ray-Bans sponsored team of Pitts Specials. Surprise! One of the pilots was Debbie Gary. I talked to her briefly, confirmed that she was who I thought she was and she recalled her early days of instructing at John Macone's Sugarbush Soaring.

Debbie has won many awards for her flying and other achievements in aviation. As well, she has instructed some of the best aerobatic pilots in the world - Sean Tucker being one of them!

This is a great video that you may enjoy. Listen for some of the names that show up!

Upcoming Events at KRCM and elsewhere / Re: KRCM Warbirds 2018 info
« Last post by Rene on September 05, 2018, 12:45:32 PM »
MASS TAKE OFF INFO


This event is for all warbirds

The aim of this event is to do a mass flyby, no aerobatics, just circuit flying while attempting formation


Event Coordinator briefing at 1245 Hrs

Take off will be at 1300 hrs


Take off procedures, It will be in succession, this means one after another with a couple of seconds in between. 

Circuit will be done following and identified “Lead” and will be done one behind the other, maximum of 2 in line abreast at all time.

Landing procedures: landing will be done individually, pilots are required to land long and exit the runway on their own power passed the flight line. No recovery of airplane on the field will be done until the end of the event.

Risks:

The risk for accident is relatively higher than normal flight, therefore:

If you don’t feel up to it, stay on the ground, nobody will judge you

Any low pass over the field must be no closer to the pilot stations than the centerline of the runway

Calls Definitions:

Inside mean close to the flight line,
Outside mean close to the wood line
On final mean you are committed to landing
Backtracking mean you are taxing back in front of the pilot station

Each pilot has the option of having a spotter. The aim of the spotter is to track his pilot airplane and to ensure safety calls are made.

It is the responsibility of the follower not to collide with the lead.  Any avoidance maneuvers must be done “away” from the Flight line.
