Status: offline 		Hi all...i have been modelling for over 50-years and just getting into electrics and i very much love the simplicity and tech aspects. Have had several foamies, etc and now building a Balsa USA Northstar and converting to elec. Going to use a 40 or 50 sized Hacker and Castle Creations 100 amp esc. I plan to standardize on Hacker and CC. My problem is the Northstar has limited prop clearence without making the engine pylon longer which i can do. I have less than 6" clearence as it is so I can only use an 11" prop in it's current design.

Can i use a smaller prop with the larger 40/50 size Hacker...they seem to want a 14" prop. How about a three blade.

Any observations will be appreciated...thx...Bo

Status: offline 		What about going up in cell count? That might allow you to use an 11" prop on a lower Kv motor (as you said... wants 14")

A50-12S can use 12x12 on 6s... maybe it can take 7s with an 11" prop.
