Thank you very much for all the input, now I can start practicing.
My question about mixing was just for knowing wether I should mix the elevator and ailerons. Maybe I can try this. Mixing out "unwanted tendancies" is not for me. I'll try to correct it with the sticks. I'm not saying that it's with great succes but I'm having fun with it and that's all that counts for me. I'm no competion flyer at all.
But anyway thanks a lot for al the good information. I'll let you know how things work out.
