4 blade props
 

Recently bought a Hanger 9 60 size mustang. Would like to know what size 4 blade prop to put on the Saito 100 for this airplane? Also, where can I find Charts for using 3 and 4 blade props for different size engines?

* Sullivan #S429 12oz tank to mount just aft of stocker. Same height and width as stocker, 5" long. Tower #LXFU45. That would give a total of 26oz.
* Would REALLY like to install flaps on this, anybody done that yet???
* Fuel pump and regulator??

Mine is still unbuilt, still planning and aquiring pieces. I tried to get a wing blueprint from H9, but no go.

Take care, Dave

Just had to say "RITE ON" Holeshot!!! Thats what this RCairport Forum is all about...helping fellow fliers like yourself. You were concise in what you were saying to Tom4man and had done the "home work" with all the numbers to go with it. Real nice "reply" and a real pleasure to hear from someone who knows what the score is and what their doing. [img]i/expressions/face-icon-small-happy.gif[/img]
Good Luck and HOOAH!
