Unfortunately, no joy !
I have no switched output at the Rud port, I have tried to reflash twice successfully but still no output. I have all the other channels as before but no switched pwm output on the Rud ch, any ideas ?

The second version works perfectly, thanks.
Very helpful indeed, I am indebted to you and the team, this is what 'product support' is all about.
Kindest regards.

I have been enjoying the 'late summer sun' with my Nitro heli, . . . Wow ! Fitting the CDI ignition has been a revelation, I now get 15 minutes of flight time on a standard, normal tank of fuel, no header tank fitted( yet).
I am running with the needles less than 1/2 turn open ! Cylinder head temp at the end of the flight around 105 - 110 degrees C, on initial testing with Optifuel 30 super SLV glow fuel the smoke had to be seen to be believed . . . . impressive ! so i started reducing the oil level and Nitro level by diluting with neat Methanol from the original 18 percent to 5 percent Oil, ( 8.5 percent Nitro ) So I have put around 8 litres of fuel through the motor and all is well. I might try fitting some carb needles from a smaller OS heli motor to get a more 'progressive' adjustment as one 'click' can make a lot of difference when it's only just open.
I would like to thank all who helped in the development team, the firmware is great, the heli is a joy to fly and with next to no smoke and oily residue very little cleaning.
Anyone who is interested in trying this conversion should do it, there doesn't seem to be a downside. ( yet ? )
Thanks again and happy flying.

Thank you for such kind words!
We hope it will fly well for very long time.
