Hi Bert,
With the TX16S I made 6 valve curves, from leaner to richer by 4% increments, applied on the beginning and the end of the curve.
With a simple button to push I can change the cruve and richness in flight.
This will allow to go quicker to find the latest final adjustment.
The Calmato has not yet flown because the gas reaching the crap trap dissolved the epoxy I had used to make it airtight.
So now I have put back a small standard glo reservoir with gas stopper, and am waiting for the weather to get better.
Keep you posted !
