The contras are measured by performance, people try combinations of prop pitch etc, RPM is not the most important factor anymore, so if not needed why measure…

BTW, persevarence paid off, after some 50 emails I sent all over the planet I got 2 brand new ones I was after, LOL.

On the Adverun style (belt and gear), the rpm can be measured by removing one prop and any optical rpm meter will work. On Brenner V4 (planetary drive), you will need an rpm module on the motor and calculate the rpm using the known gear reduction ratio. These are nice to know if you are setting up a governor style esc, such as the D3Motors D3.

Hello
Some pictures of not ugly planes during vintage F3A contest which took place last weekend with the participation of the F3A world champion Paysant le Roux who is an unconditional fan of these contests and models.

Very nice models indeed. Brings me back to being 14 flying my father’s Norm Page Mach I, complete with ST X60 and Kraft retracts.

What's going on here

I am merely a casual sport flyer who watches F3A in fascination from a distance. I have to say that this thread is illuminating in more ways than one. Very cool for a nerd like me, to learn about the rationale for the current designs. And yes, they are ugly enough to make my toes curl. And trying to resolve the two facts is quite pointless.
Thanks all.
