EXCALIBUR-4
Thank you for your innovative and relatively quiet products. I am super satisfied. DTA combo excalibur 4 blades.

I was also seduced by the principle of "satisfied or reimbursed for 6 months".
The propeller of my delta trike having more than 1000h, I wanted to try the Excalibur as well as another one graciously lent by a manufacturer.
The pitch of my original propeller was set to have a maximum static rpm of 5400t. (912 80hp)
I've got the other two on the same diet. With the original propeller, as soon as I took off, I would gain a hundred more revolutions.
With the borrowed propeller, I was losing 100 rpm. With the Excalibur, almost 200.
I don't know the reason for the loss of towers, as the take-off distance is about the same.
But the Excalibur is the only one that makes me turn on my VNE light, set at 160 km/h, in full level flight. And I noticed a significant decrease in vibration at cruising speed. The Excalibur is also the lightest.
But it's not the quietest on my trike.
Since then, I've been riding a 100hp and swapped the Excalibur-4 for a Excalibur-6 (6-blade E-Props propeller) to shorten the takeoff distance. How wonderful!
