One has the old style Hartzel 3 bladed and the other has the old style Simitar 3 bladed. Cruise performance is about the same. Climb is also about the same between the two. Both are nose heavy. The second ES was really nose heavy due to adding an air conditioning pump on the nose. Landings were really affected by this. We had to come in at 85 to 90 knots to have enough strength to flare out on touch down and the nose would drop hard and fast. To correct I made the trim tab an inch and 3/4 longer. It wasn't that we were running out of elevator but rather out of trim. Now it comes in at 75 knots and touches down at 65-70 knots and with little to no back pressure and the nose doesn't drop a bit. Moral of the story...it appears you can use any prop you choose if your willing to make the trim tab longer.
