HAPPY THANKSGIVING! Hope everyone is going to have a good dinner tonight, and go flying tomorrow!
I think we're ready to maiden tomorrow!!! Really excited!
I cut away some foam on the horizontal detail on each side of the tail section (on the bottom), and glued in about 3 oz of lead. I didn't want to put anything in the duct, and wanted to use as little as possible, so as far back as made sense. I am balancing on the CG now with the HRB 6s 6000. I don't think 3oz is going to affect the flight characteristics that much at all...and it is a jet, afterall..
Found these missiles (below) in my piles of "extra stuff", and asked my buddy to print me a few of the connectors so I can slide them off an on as I like...but I really do appreciate the additional contrast from them for visibility too. There were foam standoffs on the shafts of the missles I removed, and you can see where I glued the attachment parts on. I think they're from Freewing, made of foam and paper, so no weight added, really. My buddy also printed missiles for me too, so I can use them if I need a bit more weight towards the back.
After all the reading, I'm thinking I need to be about 10mm behind the printed CG for best performance, but I'll maiden as is and then do some fine tuning once I get used to it. I have a Lemon RX/gyro with satellite (tested in another jet, so I know it's solid), but I'm leaving the gyro OFF until I know it is flying right by itself. Then I may turn it on for wing-rock and high-alpha stuff...but we'll see. I really don't use gyros in airplanes that often - mostly drones and helis.
I set my "high" rates to the low rate settings in the book, like Mike? did in the Motion videos, with mid at 90% and low at 75%. We can always add more, but I want to make sure the first flights are successful.
I watched a lot of the full-scale videos posted here, and suggested by YouTube...wow, it is agile! Possibly tighter turning than our own F-16? Pretty nice jet - and very cool that it stays "in the box" the entire time at airshows. Wow.
Canards: how many MM's of down should we be at in the relaxed position? Videos look like maybe 1-2 degrees?
