I have the Futaba channel arrangement. In er9x the throttle stick is referred to as THR in the mix screen, the right stick are AIL and ELE. SO my mixes in the TX were set up like this. Chan 1 = 100% AIL Chan 2 = 100% ELE Chan 6 = 100% THR ??? Why THR on the pitch channel I have no idea. Has always seemed strange to me, but it has always worked. I had to completely reconfigure the bird (mechanically) and I guess that caused the reversal (probably did not re-assemble EXACTLY as it was before). But now I've changed Channel 6 to -100% (minus) THR and it's working correctly again. Thanks boowho?? |

This assumes that the heli and TX was set up correctly before fitting Flymentor. |

Without the FM I would be too scared to try such things. As my confidence and skill increases I will eventually cut the gain to minimum or take the FM off completely. Boowho?? |

Chattering servos
Hi,
I have tried to install a Flymentor to a TRex 500 (ultimate destination a very old, VERY sentimental Graupner Bell 212) but I failed As the Bell installation has all the components on a removable plate, I set it up on the bench. The components are Eurgle 9X (original) with DS615 servos. It works perfectly on my TRex 500. I then installed the Flymentor iaw Ivor Hills' excellent thread, powered it up and got a steady green. It does operate, but the servos chatter constantly with an occasional random twitch when idle. When I make inputs, the servos move in the correct direction but jerkily - as if some gear teeth were missing! It appears to under and overshoot the selection, then settles down similar to idle. When I remove the input, they return to idle as before. it is especially bad when operating the Throttle (collective pitch) as the rear servo does acrobatics! it appears to go full travel in both directions a few times before settling in the chosen position. I swopped the radio out with a Planet T5, same as before, but perhaps not as bad. Its just a bit frustrating! And confusing. Thanks, Alan ps I posted this elsewhere, but got no response - hopefully you folks can help, thanks, Alan |

I have set up Flymentor's with both digital and analogue servo's and I have noticed that some digital's do chatter a little when there is no load on them but as soon as the head starts spinning it stops or just a little finger pressure down on the swash. I expect you are aware that there are reports of DS615's behaving as you describe ( without Flymentor ) and have been returned to the supplier but if yours are working ok without FM I guess yours do not suffer this problem. Personally I only use digitals on the tail all my helis both 450 and 500 are running with Hitec analogue metal gear servo's on cyclic and most are in scale body's. In my opinion it is unlikely you have a faulty FM more likely to be a compatibility problem. The only way you are going to know for sure is to plug in a different make of servo. If you get desperate you could send me one of the servo's and I will plug it into one of my working heli's to see if I get the same problem. Sorry I can't help more. |

I hadn’t heard anything about the 615s, but I'll check. Thanks. What you said about analog got me thinking., My 1973 Graupner Bell 212 had been in storage until a few years ago when I discovered electric power. Purely on size reasons, I bought FutabaS3003. I just checked and they are analogue, so I fitted Flymentor - not a twitch. No overshooting centre when I flick the sticks. What Hitecs are you using in the 500? Thanks again for the swift reply All the best, Alan |

Flymentor On Gasser
Ivor,
First, thanks for all your help in getting so many people up and running with the Flymentor! You helped me a couple of years back getting one working on my TREX 450 and it went along way to getting me comfortable flying it without crashing. I have now removed it and run flybarless on all of my helis but was thinking of putting the Flymentor on an old JR Ergo Z230 gasser that I "inherited" from my late uncle. I have it flying pretty well without the Flymentor but thought that due to the size (thus danger in the event of crash) and age (cost in trying to rebuild such an old heli if it crashed) it might be a good idea to put it on for emergencies only. Note that I only do very basic sport flying (i.e. nothing upside down, on purpose at least). Just have a few questions for you about using the Flymentor on a gasser. First, am I going to have vibration issues because of the gas engine (assuming things are as balanced as you can get with a gasser) that will create problems for the Flymentor. Second, the heli is so old it sill uses MCCPM (mechanical mixing) - is that going to be a problem or can the Flymentor handle non-CCPM heads? Third, I currently have a GY401 tail gyro on the heli - should I continue to use that for the tail and just use the Flymentor for aileron and elevator? Finally, any other tips or suggestions would be appreciated. If anyone else has any experience, tips or suggestions, it would be greatly appreciated. Thanks.

Hi Ivor,
When you have time, could you let me know what servos you are using in your TRex with Flymentor? I think I'll get some for both helis. Thanks for all your hints and tips. all the best, Alan |

I should have said before but did not think about it, if you are trying to use Flymentor on a nitro/gasser you will have a lot of problems it cannot handle the vibrations and if subjected to a lot of vibration it will crash the heli. It has been done but most people fail. I have never tried it but have fitted a Helicommand 3A or 3D or ridged to a nitro without problems. They can now be picked up quite cheap now on ebay. Just in case you don't know Flymentor is a Chinese clone of the German Helicommand 3D. Sorry if that's bad news. |

But if you decide to try it the mechanical mixing is not a problem there is a setting for that in the programme. Yes I would leave the GY401 on the tail. |

Allen/ Niodoen. Just to be clear if Flymentor is subjected to excessive vibration the gyro's will mess up and the heli will crash you are unlikely to be able to save it.

Thanks Ivor
Trial installation will be my trusty TRex500. Ultimate destination an old Graupner Bell 212 converted to Brushless motor power. All the best, Alan |

Thanks Ivor - I'll steer clear of the Flymentor on my gasser in that case. I don't need any help crashing - I'm good enough at it on my own .
