Default EP Falcon rolling at take off ?

Have flown this plane a dozen times, had a fight with a tree, tree won.
I had another plane ,same one. rebuilt the the new one and she taxied fine.
Installed wing checked CG, went to take off and she gets up to speed and as I pull back ,she allerions to the port side into the ground?
She seems to roll in the oppisite way of the way the motor is turning.
The motor is tilted down and to the right on the stock fire wall.
Any ideas.
Thanks.

It sounds like it may not have adequate flight speed as you attempt to rotate. Could the wheels be binding during the roll out? In that case, a torque roll to the left seems likely. Perhaps a hand launch, if possible, would be more successful.

When I tested her with the wing off she went straight down the line and as fast as my cat after a piece of ham !
Turns on a dime.

I hate the way the fire wall is set up from the factory with a slight down nose setting and a little to the starboard side.
South east nose cone direction.

Funny looking, but it`s what the manual says to do , and I have flown her a doz zen times with out indecent on the other plane ?
I will giver her a check after dinner and use your checks.

Scared to death to hand launch,being that she is rolling straight into the ground port side at take off.
And I`m outta glue
I`ll keep you posted. Time to triple check.
I know its gotta be something easy I`m missing.

Down and to the right is to compensate for the prop trying to lift the nose and shove it to the left. Absolutely normal.

And have to agree with reelquick, sounds like a text book stall on take off. Too slow for flight and the prop twists the plane to the left (port for you boaters)

When this happens, natural instinct is to apply right aileron. All this does is make the stall even worse, as the left aileron drops and causes more drag on that side.
All you can do is apply right rudder to try and compensate for the left roll.

Thank You so much for the reply, I will give the rudder trick a try.
And you were right about me trying to correct with the allerions. Made it worse.
That makes sense.

I tried it again, with right rudder at take off,and the plane just wants to roll into the ground to the left at take off.
I only had one battery and it wont take another charge, so I can`t give it another try.
Out of frustration, I ordered another ep falcon.I can always use the other for parts.
I have a large balsa trainer that I can play with until the new one arrives.
Just driving me nuts on what I did differantley.
