The relatively flat blades give good performance at those speeds, and excellent take-off performance, but I expected that they would run out of puff at higher speeds compared to the high-helix props like the Bollie and the Kool. But testing shows this not to be the case, in that at the same manifold pressure settings, the Brolga performed at 86kts, within one knot of both the Warp and the Kool! The pitch blocks only come in one degree steps. 16º is a bit too fine for cruise, giving WOT 6000rpm, but 17º is over-pitched for best take-off. Since the Brolga is under-pitched, the rpm for the same manifold pressure setting is higher, but the speed was still the same...... I had expected that this large 4-blade prop would be best at take-off and noticeably slower at such speeds, but it seems not to be the case....... At WOT it gave 100+ knots, same as all the others, which was really surprising!
“If thousands of people believe in disasters, they will happen — not just because of the thought, but also those who are ignorant take harsh actions upon the skin of the Earth Mother — cutting the trees, pumping out the oil that is the life blood of the planet, setting off bombs. Earth is delicate like a small child. Most people think they can take everything, including the blood of the Earth (oil). Pollution allows harsh energies to assault the Earth, and as people cut trees, the skin of the Earth becomes vulnerable to cosmic energies that penetrate the Earth, leading to further imbalances.”
