fred cenko Posted November 20, 2014 Share Posted November 20, 2014 Greetings all Had a chat with the Contes manufacturers of Aerochute and Peter from Bolly and they have a new ground adjustable wide blade 55 inch prop which has the same climb rate as a 62 inch prop used on the Aerochute without changing the the line guard ,retailing around $1250 from Bolly .Sounds like a good deal especially given the more clearance from the lines which would be 1 1/2 inch extra clearance compared to using a 58 inch IVO prop,which is the standard used prop. 1 Link to comment Share on other sites More sharing options...

eightyknots Posted December 4, 2014 Share Posted December 4, 2014 For they are Bolly good fellows, to come up with this new 55" prop... ...but (being a smaller prop) does it use more fuel for the same distance? Link to comment Share on other sites More sharing options...
DingerPPC Posted December 4, 2014 Share Posted December 4, 2014 Fred,I wouldn't have the foggiest re climb rate but Im sure Aerochute could give you this info ,Im never needing full noise (solo) at any time that I know & my machine has waaay more lift than the one I flew for my licence with standard prop.

These new 55 inch Bollys are yet to be released,Feb next year still in their trials.I know I need a better performing prop when taking up passengers than with the 59inch IVO I currently run.Your question on fuel economy on smaller dia props gives food for thought.This URLfrom the Bolly Book in the first section under blade area vs blade dia in performance might help with your question.I still have an open mind on the 55 inch,but going to a larger dia prop might be the better option for the slower more drag Aerochute.http://www.bolly.com.au/book/Book.php?Chapter=2&Section=4 Link to comment Share on other sites More sharing options...
