The Mig 15 is an interesting plane. On glide testing it can be balanced back a little. With power it needs a more forward balance.
Today was still too windy but I found an area shielded by a tree line. The 5th proto comes in at a heavy 4 oz. It tracks very straight and level. It gains altitude with throttle and turns easily. It could use a little less dihedral and would probably fly even better and still turn well. Turns out the foam fuselage tail section makes a preferable jet duct so the pod's exhaust tube has been removed. Shaping the foam at the exit area helps the exhaust not swirl giving better thrust.
I made two circles around the field and landed into the wind. The flight was smooth, slow, majestic and realistic looking. It took full throttle during the flight which isn't desirable. At least the 6 amp ESC didn't pop.
The newest proto weighs slightly less than 1 oz empty, and about 82 grams or 2.9 oz all up. It has a 98 sqin wing area for a 4.25 oz/sqft loading.
The newest version has all paper removed from every part which saves 50% of the foamboard's weight. The wing's airfoil is now curl formed saving weight. The rudder and stabilizer and wings have all been enlarged.
