So how did they know your email address? I doubt that they are sending out random invitations.

Good stuff. I didn't realise you could get FR24 to supply the ground station but I imagine that depends on whether they already have coverage in a specific area. Many people build their own many of which are Raspberry Pi CPUs. You could build a ADSB ground station for under $40.00 a few years ago. The original bottom of the range Pi Zero is still under $10.00 but the Pi 5 with 2GB of ram is about $80.00 so with peripherals $100.00 to $150.00 would be the current price to get it all up & running.

As I mentioned you must know your aircraft. The Pitts is is about as different from the Cougar as you can get in light aircraft.

There are a number of new airship designs under way around the globe including Australia. Great when there isn't much wind but they don't perform well in bad weather conditions.

It was part of the PPL syllabus when I learned to fly but not climbing stalls other than power and wing drop. The C150 dropped the left wing quite quickly with about 1700rpm & full up elevator. My aircraft won't drop a wing at all & will fly right through the stall and then just descend at idle and up to altitude level rpm. I need to have about 2000rpm with full up elevator & then kick the rudder full over to make it drop a wing which it does quite violently going almost vertically towards terra firma.

I find stall warnings a pain in the neck. They are always going off in turbulence & come on too early at times. Know the stall speed of your aircraft. Practice it at high altitude till you know exactly what the symptoms are, like buffeting etc and know the airspeed. Have plenty of airspeed during approach especially in turns & even more especially in the turn on to final. 1.3 is the bare minimum.

Many manufacturers will use a standard product that is available and buy up stocks, give them their own part number and price them to whatever they like. The Jabiru engine mounts are from some other manufacturer but in Jabirus case they are not exhorbitantly priced though more expensive than buying them from the actual manufacturer.

It has probably been said before but young and experienced and a flight instructor means he was a pretty good pilot. The missing link is time and that hopefully provides wisdom. If it was a stall turn at low altitude then getting caught up in all the fun of it with mates that young can very easily lead to a loss of situational awareness and over confidence.

Adds weight and bulk plus the wheels not rotating assist in slowing the aircraft.

No aircraft ever built is immune to pilot error & that is responsible for probably 90% or more of all crashes.

The Cougar is basically a 4 seater version of the Sierra I built. The wing area is about 20 Sq feet bigger than the Sierra but the wingspan the same at 26 feet, it just has a deeper chord. Garry Morgan had one built when I purchased my kit. It was pretty cramped in the back. I can't remember what engine he had in it. As a comparison here are the measured specs of my Sierra as built by me.

No a terrible tragedy, not an accident. There is always a cause and it rarely comes to something accidental.

I don't know about Ipads or iphones but in the WiFi settings you will see what is currently connected. If the SE2 is turned on it will show as a saved connection if the ipad is connected to your home WiFi. On my phone & tablet I just select the SE2 & it connects & disconnects the home WiFi. As soon as you are finished & turn it off the iPad should automatically revert to the home WiFi. Uavionix is right. Battery degradation happens at high charge conditions so if the SE2 is constantly being charged it will not get a chance to discharge enough as electrons travel from the anode to the cathode via an electrical circuit to balance the charge. When the battery is being charged the electrons travel the other way but there is no circuit to balance it so the energy gets stored. Car batteries are constantly being charged while they also discharge & they only last a few years. The lithium battery in my old phone is still good & it was new in 2017. I never put it on charge unless the level was down to 20% or less. The battery has well outlived its software capabilities.

When the SE2 is charging do not turn it on. The only light should be the blue Batt light.

Check the battery charge status via software on your iPad. It should show 100% when the blue light goes out after charging assuming you are charging with a QC3 charger delivering 18 watts or thereabouts. The command is 192.168.4.1/stats in the browser of the iPad when it is connected to the SE2 via WiFi. You will get 3 greens if 1. the battery is charged to more than 66%, 2. The SE2 is connected to the IPad, & 3 it is outside with a good view of the sky so the GPS is connected to satellites in 3D.
