I need help.

For my Yakk 55 flight flex I had to add alot of weight to the nose of the plane to achieve the right cg. I have flown it a couple times with the cg tail heavy but it is really touchy. Has anyone else had this problem before?

Did you use the recommended gear?

I had this plane last year and really enjoyed it until the "flex foam" became too flexy after many flights and it was just about unflyable as it was flexing all over the place! LOL! I used micro servos, A small berg receiver along with a Castle Creations 25 amp esc with a brushless park 400 on an aluminum gearbox like the MPI. I used a Thunder power 2100 Mah 3 cell and pushed it all the way up to the nose. I had no added dead weight. The plane flew great and loved it. That plane has a short life tho as the foam falls apart after many flights.

I am using the stock motor, A 1500mah lipo battery, e-flight s-75 servos, a electrifly c-35 brushed esc and a electron 6 rx.

I am just beginning to fly planes with ailerons so would a different plane be easier to fly than the yak 55?

my UCD Flex is touchy too, but it balanced fine, added a heat sink to motor after the first one had a meltdown.
using Futaba 3110 servos, 1320 LiPo, ElecticFly 35 amp esc on stock motor
start out with low rate, once up high then switch to high rate.

it was my first aileron plane, I think its a little hard to learn on, but it teaches you to use both rudder and ailerons to make your turns.
