[NSRCA-discussion] Plettenberg Advance 30-10 ESC - Questions

I think there has always been a correlation to low-idle and slow down lines. The key is to keep it low rpm and not let it speed up to an un-commanded position/speed.
If the prop speeds up you are passing more pitch speed. Keep it slow and no-go.
With the D3, it is set to a very low rpm. I’ll get a reading next time out. It is just ticking over.
On an engine, even CDI, you have to run a rich low-end to keep the prop under control in a down line.
Thank You,
Jim

I can’t postulate a mechanism for a free turning prop to be able to turn fast enough to generate any tractive force.

Rough example.....a single blade electric idling at 500 rpm with peak rpm of 6K.....the prop can wind up to 3 or 4K in a long downline without specific ("drag") braking or governing.

It was lacking the down line and exit speed control offered by the YS - but ran exceptional in all other aspects. Pleased enough, I bought a second Invitation from Paul, with Himax, and also installed an OS controller, noting identical performance observations. Overall great, but even with brake set at 90%, there is a freewheeling of the prop that cannot be dealt with.

The D3 will not let the prop spin or freewheel or over speed at all - it is eliminated. It’s unbelievable different and the flight envelope becomes 100% in control all the time:

Perhaps my friends that have seen it fly before and after will chime in, but there is a tru visible difference in the flight profile. That’s my observations, and it really light!!

The Graupner actually has a dynamic break from the limited few weeks I flew it last year. Once the brake is engaged it appeared that the lower one lowered the low end the higher the break percentage would be. I only flew the esc after the NATs last year for a few weeks and at first I did not realise it was changing the break the lower I lowered the low end. This might be good or bad feature but I'm sure someone would be able to make good use of it. I had no issues with temperatures and it seemed like the Pyro 600 motor for the contra ran much better. I think it will work well with the Pletty or any other current motor out there.
