Hi I have my Spirit on a Gaui x3 with DX8, Lemon satellite, Dominator motor and Hobby Wing ESC. I have a friend who has two Spirits on two different helis so we thought we had it organized. Yesterday I spooled it up to just lift off but it flopped over on the right before any height. No spins. The pin in locking the tail shaft and pully was gone. I am not sure whether it went during or after the flop. Checked the vibration logs and nothing significant was there. Today, outside I started a spool up and it went over again. Nothing was broken but the boom was rotated so I put that back straight. It was tight enough. On the next try it lifted off very stable to about 3 feet than went left and crashed. Both blades broken. One servo arm broken. I noticed that the belt was loose. Tightened it up and ran the diagnostics and got 24 on the y axis. The others were very low. I can't tell if the loose tail is the problem or something else. If it was the tail I would have thought the heli would start spinning but it did not. Any ideas would be much appreciated. thanks, John |

I just ran the diagnostic test and got this: Rx signal lost Power voltage is low. My location of the satellite may not be optimal. I have a second one about to arrive so there will be 2 when I attempt to fly again. I will do a range check. I thought I had the HW Platinum set to 6v but perhaps it did not happen. Redo. I went to the basement of our apartment building and stood about 3 times the distance, ran up the motor, wiggled sticks, pushed rescue for about 2 minutes. The log says clean and healthy. Do I risk another set of blades. |

After many different considerations it appears that due to my lack of understanding and previous experience with a 300x I managed to reverse the aileron movements. My thinking was that since the swash moved up on the 300x to increase pitch it would move down on Gaui. I was not taking into consideration that the cyclic servos were mounted in the reverse of the 300x and the effect of that. When the wind drops I will give it a try on soft ground. |

I suspect that there is rather bad connection between satellite and the unit. If you can see Receiver signal lost then it is important to fix it. I recommend to do few test runs without blades so it cant be damaged. Please check satellite cable very carefully especially around connectors. |
