Beautiful Cub, is that your model? And is that you flying using a screwdriver!?
Please send us some of those blue skies!
Happy New Year
Phil
Again, Happy New Year to all!
Yes it has been my model for some years now. I saved it from an attic clean out, it originally comes from the Czech Republic where it was picked up at a clubhouse sale by one of my flying pals. I still have no idea about the design. At ~40" span it's about 1:11 scale and I haven't found any plans or kits that could be it. Meanwhile my repair skills with yellow tissue are back to standard...
What isn't seen in pic 2 are the two extra pots, added later for setting the rudder offset at the the 40/60 and 100% throttle.
The picture shows me trimming straight flight for both situations. When finished, I closed the cover...
Those added throttle/ruddercoupling trimpots:
The encoder is a Phil G. version 1, stripped down to just single channel, extended with Tiptipflyer's throttle set up, altered for a 0-60-100-40-0-60-etc. caroussel. To know throttleposition when flying together with IC collegues, there is an ultra bright blue flasher.
As a cherry on the cake I used all analog inputs for reading a herd of trimpots so I can adjust literally anything.
There's also a TX battery warning circuit in an AtTiny, running independantly from the main processor. Flashing (green LED) quickly when full, very slow for almost empty. The "landing now!" sign is the green LED turning solidly red....

Blue skies are having to wait a bit, I'm afraid. It's windy, murky and anything but winter here.....
