My stock one only has RKH grips on it.

Curious, what is the performance change this brings you? BTW I agree with your statement the more you fly it.... indoors this thing is such blast. |

At low RPM, Reynold's Number (Re= Chord X Velocity) becomes a factor. At low Reynold's Number, the lift-drag ratio becomes worse. The lift-drag ratio may be improved by using wider blades which increases Re. In my case, flight times have been increased because it takes less power to fly. The only difficulty that I have found is to make sure that the blades are approximately the same weight or lighter than the stock blades. Heavier blades or blades which are too long which slows the RPM required to fly, seemed to affect the gyro system causing oscillations. |

Good radio set up please
Ive been flying the old MSR for a while and have pretty much got it tamed. But I'm finding my new MSR X to be quite a handful. Mine sets off in a random direction on lift off and once I do get it into a hover it needs a lot of small corrections on all channels to stay there. Throttle seems to need the most attention.
I leave the model alone after plugging in the battery , have all trims centred and leave the sticks alone till after liftoff. Can anyone recommend settings to put into the transmitter to calm it down a bit, I'm using a DX 7s. I was hoping the new model would be an improvement on the old one but so far it doesn't seem to be the case. Thanks Terry |

Just dial back the rates on aileron and elevator. Way down to 30 is fine to start on aileron a little more on elevator is ok. When you get comfortable you can dial it up as you learn. John |

Thanks guys
Ill try that next flight. I've looked at the swashplate power on and off and it doesn't seem to move, am I right in thinking that suggests the linkages are correct ? Terry |

You want your swashplate tilted slightly to the right so that when rudder is applied, it doesn't move from its hover position when the gyros switch between HH mode and rate mode.
This will also help prevent the heli from veering on takeoff. |

I found out at first MSR-X is tricky but stable. Worked it from there and more it was flown the better it got. Its not a V911 or similar. I got mine almost a year ago. It was a help to go into c/p's. Day after flew this put up my mcp-x's. Only mod i did was using wider blades. Fine little heli.

Thinking of moving on from my mSRX’s to a NanoCP. Anyone interested in a package deal? I have a fully RKH upgraded brushless X, in MINT condition, and a pretty stock X w/RKH blade grips, Glow In The Dark LG, Rotors, Tail Rotor and a TON of spare parts...? Anyone?

I tried the very low rates suggested but found I did not have sufficient control authority to correct any drift. Fortunately I left a higher rate on the switches. I've found 85% throw with 30 expo on elevator and aileron and 70% throw with -20 expo on rudder works for me. I also softened the throttle curve around the hover which is about 42%.
With these settings I can hover and do right hand circuits but if I try and go left it all goes pear shaped very quickly. I can do left hand circuits with my old MSR is there something odd with this version? Terry |

Been enjoying learning to fly the msr x for the past month or so mainly in my small kitchen. This thing is a blast! I hope they continue making parts for a long time to come. I'm finally getting to where I can turn it comfortably in either direction and fly around the house. I have read about and experimented with the 'MMM' mod and also rudder to aileron and rudder mixes. I wound up returning the linkages to their stock positions but I might experiment again after figuring out that my spur gear had slipped down at some point which was messing with the handling. The mixes continue to help me turn and I'm still tweaking them as I go. Now on to my issue I can't seem to find addressed anywhere: I have recently been able to fly it outside and also once in a gym where I have some room to manuever. In circumstances where the tail rotor needs to slow down like fast turns to the left or sliding to the right, the tail motor will pulse causing the tail to wag or kind of ratchet around. I have had this happen with both the stock setup and also now with an mcpx tail and rotor. Maybe this is normal but it would be nice if I could tune out this behavior. I haven't been able to pull off full left Piros without losing control so I'm not sure if it would still happen then or not. It will go right all day long. Could it be the main motor? Feathering shaft? Other ideas? Thanks in advance if you bothered to read all this!
