Putting back the "CP2 Tail Touch" by adding back that 'non-functional?' vertical stabilizer fin  . Anyway, this is just for cosmetics

| i am happy on how the cp2 tail performs now. Definitely better than the stock tail or the usual 'speed/rpm dependent yawing' method of controlling the tail | |

| As long as the swash remains in phase even on full servo swings, there should be no shift at all.
Looks like a shaft binding issue. Take note, heli moves counterclockwise in ALL servo extreme posit ... |

Thats a fantastic conversion but looks like a bit of a handfull to fly 
Technically it flies like a ccpm heli. Remove the double pitch link and it will fly close to a lama feel. |
