in my epsilon obtains 7.5 lbs although refors all the inside in the section of the fuel tank and fire wall, use servo of normal size, and I mounted a super tiger g90 with APC 14/8 9,500 rpm.

In my Epsilon when i "try" to do Harrier the plane begun to move the wings side to side (like stall) and when i do blender and do the flat inverted spins, the plane move the first 180º very flat, but the seconds 180º get up the tail....

Please if anyone know some secret to do in correct form thees aerobatics please tell. I read a lot of forums , go to directions of 3d but the instructions are the same, something i do wrong.

Thanks
