Axial play in the grips
I'm running Eflite 'B' grips w/Boca bearings on Microheli's hub w/high-durometer dampers. MH sells a couple thicknesses of shims - 1.25mm & 1.35mm. With the 1.25mm shims, there is no axial play in the grips with the stock FS. I just switched to the MH titanium FS, and the grips are still tight with the 1.25mm shims.

No, I never confuse pitch curve setting and travel adjust setting. I know exactly where you're coming from and why the intention of "travel adjust" and I don't disagree with them. But saying it limits servo travel is not the most intuitive word to describe what it does. And saying scaling is only a side-effect (meaning there IS indeed scaling which is what the point I've been trying to say) is totally different than saying no scaling is involved. Setting a pitch curve of 0-25-50-60-70 and 100% travel adjust on up and down pitch travels provides identical end result as setting a pitch curve of 0-25-50-75-100 and 100% down-pitch travel and 40% up-pitch travel. You can argue the intention is different and it'll affect other things like mixes, etc., but the resulting pitch angles will be identical in the 2 cases.
When you turn down rev-limiter by 10% RPM of an engine, you only limit its rpm from going beyond the preset value 10% lower. I'll never expect it reduces throttle to the engine to scale the entire rpm range. |

I agree. I also think that setting this heli up with 100% throttle across the curve while it won't over speed this head is a bad lesson to learn for growth in the hobby. Better if new people set up as much as possible proper setting (granted they will still have to learn the ccpm menu later). Learn the inter action of pitch and throttle curves for later. Finding that curve that will transition to throttle up and back smoothly on this heli will most likely save a lot of money for them us later. Seeing a bad setup too will help see what we don't want our heli to do. In a ccpm heli you always set EPA and leave it. Thre is a good video on the genius cp thread that deals with binding cyclic and that heli not holding that tail because the binding was causing high current draw. So it would seem we may look at that here. Although I can't access my heli until it and I te settled in Thailand. Maybe someone could check cyclic binding on the mcpx. Arthur |

It isnt the most intuitive to you because you try to use i for more than its purpose. If you setup a heli mechanically correct and the pitch curve for what it is truly for, the term will make perfect sense..even more so when you use ccpm mixes. Quote:

What changes is the servos overall movement and is why it affects the pitch right away. But still isnt real scaling or proper setup and why i disagree. If you do much artwork you will see scaling is making something retain the same form but make it larger or smaller. You can mess up what you perceive as scaled pitch curve via endpoints simply by changing the pitch curve itself therefore loosing the scaling it seemed to have because it wasnt ever truly scaled. If the pitch was ever truly scaled then the pitch curve wouldnt be able to change it. The effect of scaling you see is simply improper use and not full use of the the functions of your radio and is seen as such when you override the what seemed as scaling with a simple/minor pitch curve change Bottom line is i know you can manipulate the pitch curve via endpoints... But I only have one last thing to say I hope you come to understand what i have been saying with all the confusion that it brings when you want full pitch travel for idle up position 1 but can not get it because you manipulated the endpoints to give you a mellower pitch curve.. |

I think what you misunderstand me is that you always think I confuse pitch curve with travel adjust. I never intend to use travel adjust to do the pitch curve's work since day 1 but you keep trying to say that's what I think.

My heli will not spool up anymore. I had the clubheli brusheless system on it and it would not spool up it took a couple throttle backs but now it will not spool at all. I removed the brushless setup and installed the stock motor and still no spool up. I have been through my settings over and over and i have also rebinded it a couple times. Should i just get a new board.....well whenever they come in stock at horizon....BACKORDERED as ususal with all the crap ppl need

Or let me use another example to illustrate. Let's say the mCPx runs a rotating servo arm for cyclic instead of a linear servo. Reducing "travel adjust" is like swapping to an inner hole of the cyclic servo arms which scales the entire pitch range. Of course it's going to affect every final pitch angle except 0-pitch.

Kind of like leaving 70% or more stick for hovering on a cp heli instead of a beginner trying to make it hover near 25%. Sure you can make it hover even at 0 stick but thumb memory is nice to fall back on when you finally flip that idle up on and flip the heli I had to change a lot of what i did in my first few heli's because I intitally taught myself incorrectly and made a mess out of my radio. I had issues with thumb memory and in the beginning of trying to learn how to flip. I would flip and on recover I would go to what use to be a little more than hover....whoops! It wasted alot of time, money and relearning to setup heli's right At times wonder why i had a computer radio with all the functions if i didnt use them or used them wrong which inturn messed up other settings on my radio... that cost me some money |

Might sound silly but is your throttle hold off? Are your throttle points on bind a there lowest values? (dont recall on the mcpx but on some esc's if it sees even the throttle trim as above 1% it wont arm) |

yes throttle hold is off and i dont see any burnt marks and i changed the throttle points to -125 in my dx6i completely clueless. It had a problem with spooling i just thought it was weird because of the brushless setup but now it wont spool at all if anybody knows any helpful suggestions

Guys - do you think it's OK for me to put some CA on the tail boom where it splintered? I'll obviously have to be sure that none of it goes into the slot on the frame or I'll never get it back out but what if I just put some medium CA (I think thin might wick into the frame) over the splintered section?
Any issues with this? |
