PRO.MECC AEROSPACE SPARVIERO : the ambition at a low price

GLORIEUSE-3
Constant Speed propeller performing well on the Sparviero.
Thank you for your welcome, for the assembly and for the performance of your products.

DURANDAL-3
A big thank you to the whole E-Props team for their support and their impeccable service, despite their holidays, when we changed our propeller from a variable pitch to a Durandal 3-blade carbon model.
On the balance, the gain is 7 kilos and on the performance side, our Sparviero from the company ProMecc Aerospace of Mauro Donno now has a cruising speed of 220 km/h at 4900 rpm instead of 5500 rpm for 170 km/h before.
Thanks again to them for this particularly effective change and for their great professionalism.

DURANDAL-3
I'd like to make a contribution by recounting my experience using an e-propeller with a ROTAX 912s on my brand-new Sparviero I picked up in Italy and flew back.
In another post, I said I was doing 120 miles an hour at 5000 rpm at 3000 feet. My propeller was throttled up to 25 degrees with the tool provided by e-prop.
This stall has given me the satisfaction of taking off from a variety of loaded, heavily laden terrains.
Indeed I had 230 km/h at 5000 rpm but almost impossible to take more revolutions when cruising.
It was at the urging of a pilot who wanted at least 5,500 rpm on the run, that I changed the setting to 22 degrees.
So I actually have more laps at takeoff (5300 rpm) but at 5000 rpm I fell to 200 km/h.
I don't feel like I gained any takeoff distance from the 25-degree setting. I don't feel like I gained any takeoff distance from the 25-degree setting.
It's the actual propeller pull that matters. I'm fine with 230 kilometers per hour at 5000 rpm, so I'm going to put it back down to 80. I'll put the throttle back on.
Now we're in the real world!

The elements and the technique are evolving, especially with regard to the propellers. I have an e-props propeller on my sparviero and I CONFIRM that in level flight the rpm is lower than the take-off rpm (5500 rpm) at the moment. I know it's a bit confusing, it's due to the 'constant speed' profile of this type of propeller. In my previous setting I did not have 5500 rpm at takeoff, I had less and I could not get more than 5000 rpm in level, but I had 230 km/h at 5000 rpm at 3.000 feet Temperature 15°. Since then I have been able to test my aircraft, its 912s and my e-props in very different and new conditions for us: from 0 to 12,000 feet, from +15° to -15° in search of a climb, cruising for more than 1500 kms, taking off on hard ground and on dry or really wet grass, alone or with two strong guys like me + fuel + luggage. For me, having 230 km/h at 5000 rpm suits me very well, making a speed record at 5800 rpm for 3 min is not interesting. That said, I am not able to give you my intake pressure, even if my installation provides such a measurement, this function is not operational for the moment. As for the consumption, coming from the plane: it will always be less than equal punctures!
