Look at 3:55, the rudders kick in like a V-tail just like the F-22 and F-18 do. Thats how the full scale planes do it to overcome their configurations.

I've reduced rudder throw significantly and added aileron mix, hopefully it will correct the dutch roll effect some. I can tell you that it rolls with rudder just as fast as with ailerons......scared the crap out of me! :D

LOL my F22 was the same way. One time I gave it to much rudder in knife edge and it went from 170mph to about 80 in a few seconds with a violent snap roll..... I thought the plane broke up at first.

Well, got to the field, turned on radio and gear was in up position. Nose gear collapsed and snapped the nose gear door out. That kind of set the mood for the rest of the morning!

Oh well, decided to still fly as I really wanted to test the Cortex. I took off with 50% gain, but gear wouldnt come up, so I flew with gear down. Im impressed that it still flew pretty good with gear out. Aimerons were trailing a bit so I increased gain, to the point where I didnt like how ELE was working, then backed out. All pretty good. As i was driving home I realised that I only connected one AIL servo, so I only had half of gyro correction (no wonder it felt a bit lagging!).
I also added nosewheel steering correction, but it didnt really help as expected. It was still touchy during takeoff, and was not tracking well......but I think there were other factors present too. I just cant get this thing to brake without veering to a side, and scraping a wing tip. So, I cant fly this on a club runway until I get this sorted out. That being said I lost my GSW jet rally window, which BLOWS!.......but I think I like this model enough to warrant taking time to make right. Gotta fix a fuel leak too.

BTW the aileron to rud mix fixed the dutch roll problem at knife edge. It can now knife edge fine.

Same with Rookie, Harpoon etc. I'm still working on the DerJet one and I had already set that with small rudder movements!

Dave how is DJs coming along? Done much flight test?

Would love to see that F-35 at West Texas Jets next week!
