Blade,

There are newer versions but the updates are very, very minor. 1.4.2 solved 99+% of the issues. 1.4.3, 1.4.4, and 1.4.5 (just for you) were very minor tweaks of certain aspects. The latest manual still says 1.4.4 but the software is now 1.4.5.

I should add that I have also done truely custom features for some customers (mostly guys flying Ziroli planes that need specific tweaks). I am open to having a 1.4.X.JOHND and do so if there is something unusual you need. There are people out there with fully custom features running on their sync units designed just for them - at no charge - YET.

I can even make a few suggestions for scale guys:
- sync bomb drop
- gun control
- other lights and sound devices
- running lights
- different display heads and display options
- etc, etc

I am out of ideas for sport flyers (like me).

...think of the twin sync as a computer radio onboard the plane...that you can control with your radio. Just send in ideas. I have five new products getting ready or going into field testing now as a result of these two RCU threads...

The difference in 1.4.4 and 1.4.5 is that in rudder steer mode rudder steer is disabled in the event of a dead stick and rudder has no impact on throttle on one engine.

So I here by dedicate 1.4.5 firmware to Blade47. 1.4.X is dedicated to 2engsout - Thanks for all of the testing!
