Springs for a reinforced cyclic gimbal, new force trim mode!

I have finally been able to go to the local car parts shop and buy some springs for the gimbal. Here’s how it looks now:

Reinforced gimbal with springs!

 

I should start by saying it works just great. These springs are from some Lada’s clutch (i think they’re for the pedal), they are 55mm long when compressed and about 11mm wide. I am pretty sure any similar spring will work great, just pick one with light or moderate tension.

More (a lot more) below!

Attitude trim with B8 stick hat switch option added

You can now move cyclic around while trimmed with a hat switch of a B8 stick.  This is how it works in a real 407. You can do it in X-Plane with key assignments as well, but Simchair handles this in a better way with its adaptive force trim option. This option will not release trim until cyclic would be in a vicinity of an initial trim position with a given deviation. You can disable this feature when it’s not needed by setting B8_HAT_SWITCH_MODE to “HAT”.

Please update your master controller firmware!

Thoughts on sensitivity of controls

I have been testing new hardware more thoroughly and noticed, that different sims have very different controls sensitivity settings (and ways to adjust it).  More than that, some of the sims tend to react on even the slightest jitter from Hall effect sensors and ADC (which is really almost nonexistent), while others ignore it completely.  That means that often, there’s a need for per-sim or even per-aircraft setting.

Simchair MKIII cyclic and pedals are sensitive enough to emulate the control response of lightest and twitchiest helicopters out there. But what if you feel it is too sensitive for the particular helicopter model you want to fly? Or, maybe the sim you are flying in treats joystick sensitivity settings differently, or even doesn’t have proper controls settings at all? What if setting curves is not what you want, but your sim doesn’t have any linear sensitivity adjustment options?
