i have been flying electric now for 6 months and love it
but never happy with overhead line tension with my planes
i have tried leadout rake ,tip weight ,thrust on my motor and non of them have really helped
but i decided to try a different prop
a normal 11x5.25 brian eather carbon prop ,and all the armchair experts said it would use to much battery
i must prove them wrong as i have 21% left with both props
also the 3 bladed prop has cured all my line tension problems

As I have stated in the past, "Each airplane power combo takes different props even of the same airplane design". I am no expert by no means, but, am willing to try things to see what helps. But, am glad you are getting things to work.

Paul,
Nice to know that 3 blade prop is working out for you. Especially a CF 3 blade prop.
Kudos also for your experimentation. H^^
Exactly what CF prop are you using and from what Vendor?
Thanks for posting your success!

Hi Paul,
Glad things are working well ... now if only there was a pusher version of that same prop.
take care,
