Clearview questions

[ChrisA]

Have just bought Clearview. Very impressive.

A few questions for Stefan (or anyone else):

Is there a manual available/guide to the heli params?
Can anyone suggest a trainer heli for Clearview - maybe something Fixed Pitched (or a way to FP a CP model)?

I found it incredibly easy to hover in FMS (regardless of model). In Clearview I find this almost impossibe - hopefully due to the increased realism. Is there any way to reduce the twitchiness of the model, without reducing the realism?

Thanks

Chris

I personally use the micro-heli in CV. It seems the closest to my fp. I look forward to other answers however. I would also like to lengthen the throttle, as it seems that 1 notch goes from on the ground to 10' up

Goodluck

Volwrath,
I believe that is due to the throttle curve throtcurve1. The Trex has the following (fairly smooth):
throtCurve1 0.0 0.3 0.5 0.8 1.0

whereas the micro electric has:
throtCurve1 0.0 0.5 0.8 0.8 0.8

You could change this to something more linear?
I also guess that to make a CP heli FP, the pitch curves can be changed (I think that throtCurve1 & pitchCurve1 are used in Idle-Up off, and the throt2 & pitch2 are used when Idle-Up is on).

You are quite right, for fixed pitch, make the two pitch curves flat at whatever degree you want the blades to be, and define the throttle curves as you want. Start with linear throttle curves. Then, set the model weigth. Then set the rotor RPM - like 1800. This is the RPM at max throttle, at less will be proportional to the throttle curve. Set governor off. To finish, adjust the blade diameter so the heli lifts off at above 1/2 throttle. The next is to adjust the cyclics the way you like it.

Thanks for both of your posts. I have played around with the pitch curves somewhat, but need to go in and play some more.

You can also adjust the cyclic exponential as well cycExpo, increasing it will reduce the cyclic response near the centre.

I thought cycExpo _was_ cyclic exponential? If not:

1. What is cycExpo/rudExpo
2. How does one adjust cyclic exponential

Chris, sorry to confuse you yes you are correct I ment to put brackets around cycExpo to indicate that it was the parameter name in the params.txt file.

rudExpo is then the exponential on the tail pitch, though this probably doesn't need changing in most cases.

To adjust either load the model in ClearView then select "Advanced Model Setup" from the settings menu. This will then display the full parameter list. Scroll down until you find the appropriate parameter where you can change it.

Soon as you accept the changes they are active in CV and you can test them. If you accidentally mess up values then you can revert everything back to the installed values by selecting "Restore Defaults" from the same parameter change screen.
