I see you have already solved the airflow problem. I had not put anything between the firewall and the first gear former. Common sense told me that was a mistake but I had to see for myself. Now I know for sure. Yes it will balance on the tube with 3421s in the tail and the DZ upfront. I had to mount the battery at the rear of the LG main brace. and rudder servo in front of the rear wing anti rotation tube. I flew it 5 flights today, 8 rokunds of Intermediate and Dan Curtis flew it one wring out and trim check flight. Only comment other than WOW was some push to the belly in knife edge with both left and right rudder. Trimmed for this with the Trans. 10X. It is a fine flying machine, and I'd recommend it to all. It is the lightest pattern plane I've flown, and it flies like it. I will put it like this, It flies a lot like my Eclipse, and it wont replace my Eclipse, but it's a great backup plane.
