rotax rick said the best way to adjust fuel air mix is run it around 4000 rpm and get a little squirt bottle of premix gas. Give a little shot in the carb when it's running. it should stumble a little when you ad fuel, if it doesn't it was too lean.
I had a charging problem with one of my 503s a year ago. The yellow field coil wires coming out of the stator showed open wire. Pulled the engine off and the flywheel (magnet wheel). Saw mechanical damage to field windings. Apparently a small chip of the insulator material around on of the cores broke of and was caught by the spinning flywheel. Broke top wire of a field winding. Carefully removed stator plate with the field windings. Cleaned up as best I could. Unsoldered lead wires and took off two turn from the damaged field coil. carefully spliced wire back in and rewound the coil and reconnected. it showed a few ohms that showed field coils now in tact. Reassembled and reinstalled. It then produced AC voltage and is properly charging now. Carefully applied glue to any loose insulation surrounding insulation on any cores. Good luck with your engine. let us know what you find. Bill
That looks little scary right in front of a prop that is sucking air into it. Too bad can't mount a flywheel where the prop is to tune it probably would not have the correct load.
Howdy! I’m considering getting my recreational or ppl and purchasing a challenger II Lyncrest would be ideal for me as I’m in the east side of the city Curious what’s the annual costs of owning one of these? Insurance, hangar fees, inspection etc?!? Lyncrest I thought had outdoor tie down spots for pretty cheap - last I looked at their web site was several years ago and can’t seem to find fees for anything. Any help greatly appreciated 😊
Annual membership at Lyncrest is $500.00, which allows you to tie down year round, OR build a hangar on site. As for insurance for the airplane, that greatly depends on how many hours you have. I am waiting for quotes for insurance, as this spring I will be in the air. So I don't have any numbers on that right now. Hangar fees depend on the owner of the hangar, but ranges from about $350.00 to $600.00 monthly, depending on if it's heated and other factors. As for inspection, well, that too depends on who is doing it. If you build it, or take a factory course to do your own inspections, the cost is what ever parts you need to replace. If you are paying someone, I have no idea what that would cost. I hope this helps answer your questions.
When you shut the engine down and pulled the aircraft in, back in the day in hangars I was working in, you would have heard the dulcet tones of someone yelling, “shut those hangar doors, you @*#”%/;: €^¥
Good to see it’s Alive,,, beautiful dashboard, one of the kind for challenger 👍.
Thanks for the compliment.
Sounds smooth, good work!
Thanks, it’s amazing what going back to basics can do for setting up carburetors.
I got my rebuilt 503 running for the first time last night too, I love that sound, reminds me of snowmobiling :)
Yes it does!
Pleased it went well, engine-wise 👍. For the electrics being an easy/cheap fix 🤞.
Thanks, I too am pleased it went well. Cheers.

I hadn't seen that, but it does make a lot of sense.

Thanks , I will be doing a disassembly soon and post the results.

Ya, I’m super cautious when doing anything that close to the prop. Not a place to be distracted, or to rush.

@@challenger2ultralightadventure thank you kindly …

Ahhh, the joys of working in a shared hangar. LOL. Cheers.
