Yesterday I had the first test flight of my new Venus 40, two good friends was helping me with the trimming and balancing of the plane. They are serious Pattern competitors with some won contests under their belts and they were very amazed how this little plane was flying but they had two commentaries that I want to share with you all folks, I need advice of them who had this plane and had flown successfully:
1.0 Center of gravity per the instructions should be 4 5/8 from the leading edge
In my case I am flying with a saito 72 and, when inverted i goes down too soon so the experts had told me that this plane should need the cg moved to the back.
2.0 The thrust should be moved a little more to right because of the torque of this particular engine.
Please share your experiences.

Thanks.
Alfred.

I'm flying mine with a Saito .82 and had to move my CG back probaly about 1/4 to 3/8 inch. Now when I go inverted in a 45 degree up line and release the elevator it will go into a gentle downward arc. I mix out the pull to the left with the transmitter.

My initial set up was considering to use a Saito 82, but I had a 72 around with out a use and decided to give it a try, no regrets since it flies the Venus great, not overpowered but also there is no lack of power. initially I set the CG right per the instructions but when inverted the plane tends to go down abruptly (more than what is comfortably), I moved the battery from the tank place (that was giving me a CG of 4 5/8 from the leading edge) to the back of the servo tray just under the elevator and rudder pushrods, and performed a few more flights and in the hands of these guys who have won several pattern contests and that have told me that the plane still is nose heavy. I do believe in them but also want to know if some one else has moved the CG to the back and what far.
Thanks again
Alfred.
