Our new SFXPC3.0.5e release now has the bidirectional turrret turning sound feature. The new release can be downloaded at
www.modelsolutions.ca/downloads. You can get the full CD-ROM contents (advisable as the manuals have changed a bit) or just the firmware upgrade.
When using the turret turning feature you nudge the turret stick left or right a bit to start the turret startup sound, and as the stick is moved left or right the speed of the turret sound will increase. When the stick is returned to the centre position the turret stop turning sound will play (if there is one).
Note : If you return the stick to centre immediately after nudging it to start up the turret sound without moving the stick further, the sound will continue to play. You have to move the stick beyond the initial startup position in order for it to switch off in the centre position. This is either a bug, or a feature, depending on how you look at it!!.
We will try to fix that issue in a future release. We have done a little more work towards the throttle range feature we are planning. It has to take turns with all our other development work though, not to mention filling customer orders of course!.
Incidentally we have a very positive product review, and an advert in the July issue of the U.S. FLY RC magazine - hope you can look at it in a bookstore!
