i have owned 2 blades the 1st had 4-1 troubles so my hobby shop guy gave me a new one. the 2nd one hasnt been much better seems like a money pit to me. i was flying 2nd and landed the copter and it rolled on its side and bent the main shaft so i replaced the shaft and it has not been thr same since. i have talked to the techs from the manafactor and all they know is send it back. can anybody help i have alot of slop in main rotor thanks.
