I agree with everyone. The funtana needs more rudder and a .70 is kinda marginal in that plane. I flew mine with the saito .72 (lighter and slightly more powerful). While I did get it torquing on the deck it sure did strain to pull out. After a couple of crashes and an ounce or two was added then the .72 was just not enough for it. So I sold it and got an Accel Hobbies KatanaP .40 and WOW.
