hope to get some help, i maiden my gp christen eagle .46 yesterday and it did not go so good. at first i tryed to take off in the grass but it would get the tail up and then would have a violent nose over, the elevater would not hold it down. thought it might have been the grass so we went to the concret on the third try, well i got it in the air but had no elevator control . i had to pull almost full up elevator and wide open throttle to get level flight. well..... most should know how the rest went. this is my 10 plane i have built and the first i have crashed. the cg was right i checked it my friend at the field checked it so it was what the manual said 100mm back from the le of the top wing i had to add 4.5 oz lead to the firewall. anyhelp would be nice. thanks
