KDS Flymentor
I am using FM on my Belt CP (a 450 size heli) and Trex 550 E and am very happy with it. Now thinking of buying another one for my new KDS Innnova 600 but my KDS is a flybarless heli so I need to buy a new FB head first to be compatible with FM. I am willing to do that as FM is the cheapest auto pilot system that I can find compared to DJI which I installed on my Trex 500 E and 700 E or Helicommand Rigid. So even with the cost of the new FB head, the FM and the head together are still cheaper than either Helicommand Rigid of DJI WH Lite. Granted, the overall capability/feature may not be as good as the other two systems but it is good enough for me. I don't fly 3D.

Hello again:
Hello Ivor: With your help, I've made great progress! All that's left to do prior to a test flight is to get the FM gain controlled to function. I'm using JR XP-8102 and have retained my original gyro and controling it via Aux 2, leaving only the gear channel for the blue wire. When it is conected to the gear channel, the indicator on the FM changes from red to nothing when switched. How do I confirm if the gain is actually changing? With a single throw switch, what options of control are available? Of course I would like all three. Your advice please. |

Pre TEST FLIGHT
Well theres a small prob. with getting the servos working. When i hold the heli(B-400)Tip it to the left & Right the servos operate the proper way(opposite of your lean)When i tip Foward the servo follows the tip and the same for leaning back. My servos are set as follows in servo reverse mode( ser.$1=Nor. /ser# 2=Rev. And ser #3=Nor.)Ive tried several diff. ways but when i do get the foward &backward servo to work properly the L&R servos are not even close to working properly.My stick inputs are all correct . Dont know what to try next.

Hobbyking KK2.0 on Belt CP V2, Possible?
I have bought one of the Hobbyking KK2.0 multirotor controllers and wonder if anyone has already set one of these up on an Esky Belt CP V2? Or even a King3.
I can't find anything by searching the forums, so I may have to self-teach! This is the controller, http://www.hobbyking.com/hobbyking/s...723&aff=754418 |

I am having trouble with my tail during the flymentor setup. I have tried to follow all the videos. I dont seem that have any left rudder input at all during HH mode. If I change to rate mode, i have left rudder input. adjusting the servo travel settings only seems to affect the right rudder input in HH mode ?
left rudder stick is completely dead in HH mode. any suggestions guys ? |

In rate mode the servo moves to centre. In HH mode the servo will creep to one end but this causes no problem in flight. Gyro/servo direction should be set first under the servo tab. Then set stick/servo direction under the control tab. |

Good news, I managed to get this thing in the air. It flies fairly stable now in position mode. I have only test hovered it inside on the carpet. I noticed during the hover that the led is flickering green.
Im guessing this is because indoor lighting isnt the best and the carpet isnt enough contrast for the camera ?? Also, Do you fly with the flymentor in HH or rate mode or is it personal preference ? |

The problem you reported with the tail servo has been reported a few times but nobody has come back and said how they fixed it, it would be good if you did. I have set up about 25 Flymentors and never seen the problem but would be very interested in what caused it and how you fixed it. Your report may help others. Thanks in advance. |

With the tail servo not having any left rudder movement in HH, I set the heli up in rate mode as you suggested, then just switched over to HH and once in the air, it did in fact have left rudder movement (As you said it would).
When I go from rate to HH, the rudder servo moves to one side and requires adjusting to keep it straight in the air. I guess you just decide if you want to fly in rate or HH and set it up to fly nicely and leave it. I have still got my tail servo movement the wrong way around though. Left rudder stick gives me left movement on the tail slider and vice versa. Will need to adjust stick reverse I think. |

Yes you need to reverse yaw under the control tab. I normaly set up in rate mode mechanically so the tail holds without trim or stick input, then switch to HH and set the best gain it does often need a few clicks of TX trim to get it to hold but only as well as a cheap piezo gyro. You can also use a little tail servo trim under the servo tab. Why not try a seperate gyro I use the Assan Ga250, its cost about $10,is very small and works very well. A big improvement over the FM tail gyro. |

Can gain be set with a two way switch?
Everything is done with installation of a FlyMentor, except how to manage gain from the transmitter. Using a JR XP8103 with only the retract two way switch available. At a minimum, I would like to have off/balance function. Can this be done?

Connect blue wire to spare channel on reciever and set the 2 way switch to that channel. Go to end points ( travel adjust ) and set values to select FM off and balance, off is off but balance will need some playing with the set the best gain, try 65 to start. But as always I recommend you use the software gains ( blue wire disconnected ) for your first flights. |

Personaly I fit the FM gyro under the heli just in front of the rear skid, I just fix the pad to the top of the gyro so it remain the correct way up and I fit a seperate tail gyro in the normal place on the boom mount. Others extend the boom mount with a piece of ply or something and fit the 2 gyro's one behind the other. |

Ahh, I see. Where do you plug both gyros in though ? Does it require additional setting up to have 2 gyros ? I actually have the 250 mems gyro from hobbyking and have never used it.
Another quick question. Is it ok to use dual rates with the FM ? I have dial in a bit of dual rates and expo from my DX6i and it still seems to fly nicely. Is there anything wrong with this ? |

Yes you can use some DR's, FM doesn't like a whole lot of anything. However; on installation make sure all your curves are flat, trims and subtrims are zero and one of the most important details to me is Zero pitch and 90 degree servo arms at mid-stick. Per IVOR's sticky. Last edited by Felix the cat; 10-15-2012 at 06:44 PM.. |

Expo and duel rates are adjusted signals from the TX sticks so you can use as much as you like without effecting FM's ability to stabilize when you release the sticks but dual rate will reduce the amout you will be able to move the swash with the sticks. Personally I am a steady flyer no 3D or stunts so I use a lot of expo to give me a lot of control around centre stick but do not use dual rates,don't find it necessary. |

Ok will give it a go then. I am not having any trouble with the tail at the moment though.
I have only every flown the FM in position mode. If it were to be used in a scale fuselage, at a higher altitude in balance mode, the heli will still be alot more stable in balance mode (using the 3 axis) than with no FM at all, right ? |
