Just finished my e-prop installation and did a bunch of testing by flying at 3500 density altitude. I’m curious to compare this to others and what you settled on.
Baseline, old Sensenich 2-blade on an E-LSA w/ULS and no wheel pants.
I’m curious what others are seeing and choosing as a trade off with this prop? I’m debating keeping the 5300 climb or go back to the 5200 climb pitch. At the 5300 pitch it has a bit of cavitation until it starts rolling. I did find I can “roll in” the throttle to help with the cavitation.
It’s a nice prop. Very light and easy on the gearbox and shutdown. A lot quieter and less vibration. I haven’t dynamically balanced it yet, and suspect it won’t need anything With how smooth it is. The center pitot tube is really nice and integrates well with the spinner. Adjusting it as frustrating as any other prop you have to make small adjustments per-blade, I did find if I loosen up all the screws a half turn it’s easy to do a .5 degree adjustment, and if I loosen up the screws a quarter turn it’s easy to do a .1 degree adjustment.
