| Ok , for those who have the shultze speed control , it look like a throtle end point problem . The controler is fast enought for this motor , here is the answer of shultze:

### In the heli mode the travel is fixed, so all adjustment have to be
made in the transmitter.
### If we would let the controller learn the travel, you could not
calculate the headspeed by the transmitter values.
### Another different thing is that you are using the speed governor
mode,
### so the servo signal is not proportional with the power,
### the servo signal is proportional with the RPM set value.
### At high rpm and a 2-pole motor that giving these shaft speeds:
### 1.10ms servo signal means stop,
### 1.15ms servo signal giving 10900RPM
### 1.90ms servo signal giving 118000RPM
### For your setup and 2200RPM you need a set value of:
### 2200RPM * 6(gear ratio) * 14/2(motor poles) = 92400RPM
### So you need (92400RPM-10900RPM)/(118000RPM-10900RPM) * 0.75ms +
1.15ms = 1.72ms.

Ok , so , to have full rpm , we need to get out a signal that last 1.72ms on the throttle chanel ( chanel 3 for almost every one ) ... I think that there is someone in the club who have a gizmo( from hitec ) where you plug the chanel that you whant to test and see this frequency ... The problem is zero is suppose to be 1.10ms but on some transmitter , with the throtle stick full down , it give around 1.25ms and at full throtle , give 1.65ms . This is why , when i switch from one brand of transmitter to the other , sometime i can achieve more servos trow ( i had this particular problem with one of my parc flyer ) . With a Jr radio , i was able to achieve more travel on a particular servos but not my futaba ... that will translate in more head speed on the Maxir ... i will do more tests with my hitec transmiter tonight . |
) we never broke anything on the tail . I mean , no tail pinion , no tail grip , no slider , no tail blade ... i don't know why ... and i really like to have the ball link stock on the slider . The other good point compared to a shogun or hornet II is the full closed gearbox ... it's much more rigid so you don't end up with all the gear eaten after 3 battery pack ( no play between the gear ) . The only thing i asked Ian ( Ian is one of the guy at LaHeli ) about the desing is to have 2 bearings in the tail grip instead of just only one ( to prevent side play ) . He said it is not a necessity because the tail blades are desing to center automaticaly no mater the 'slop' in the tail grip . But they are thinking about it anyway .
