Hi,

I have been using AXI 2808/24 on my Jumping Jack. It has come heavier than expected as it needs high capacity and thus heavy batteries. I've been using KOKAM 2000mAh and Thunder Power 2100mAh. I'm using a balsa stick mount that has broken twice, I plan reinforce it with some carbon or fiber cloth. With this combo the plane has to fly fast due to extra weight and can not 3D as expected, it is around 650gr. Power is more than enough with APC 11x5.5E, but wing loading has been increased dramatically.

It can pattern very well though, I enjoy flying pattern with this plane, however I have reduced the throws to fly smoothly but they are not enough during landing approach due to extra weight. That's why I broke the stick mount last time. I can fly the novice schedule pretty well with this plane.

If I were you I would go go with the recommended configuration Hacker inrunner B20-15L and would use the Hacker mount supplied with the new kits. You will not have to use as heavy batteries as you'd use with the outrunner. I plan seriously to switch into Hacker inrunner.

That's my 2 cents. Regards,

Nick
