I'll do a compromise. I'll program two values for the throttle to elevator mix (full and mid throttle values), but if only the full throttle value is set, it will calculate the mid throttle setting automatically. So you'd only need to set the full throttle value, but you could set a mid throttle value if needed.
I doubt most people would use the throttle to elevator feature with I/C engines as it is usually so easy to put some down thrust in by putting some washers between the engine and bearers.
While I'm at it, would there be any need for a throttle to rudder compensation mix? I've never used one, but then I've never used a throttle to elevator mix on an S/C model either. In fact, all my S/C models don't have elevators
Finally, I'm feeling too despondent to do a separate post on the progress on the 3D printed OS Pixie MK2 case, so I'll do it here.
Printing the lid is getting beyond my ability (or at least the ability of my modified Velleman K8200). Or maybe it is the slicing program I'm using, as the detail on the printed lid is not replicating what I've drawn and seeing in 3D viewing programs. And worse, last night I decided to upload the STL file to get it printed commercially and three different sites say there are manifold errors in the STL file. I didn't know what a manifold error was until I looked it up on Google. And I found nothing on how to avoid manifold errors when using OpenSCAD. So is it the manifold errors causing my printing problems? Or is the detail too fine to 3D print?
Maybe I should have taken Neils advice and used a different 3D cad program. Hopefully, I'll get enthusiasm back before the weekend and have another go at printing it using different settings and take it to Ponty.
