RE: la 40 too small
 

Hi!
And it will take off much faster and fly better with a 11x5 ,11x6 or 12x4 APC or RAM prop!
AI have said many times before, a 10x6 is to small prop for a OS LA .40 at sea level.

RE: la 40 too small
 

I have used a 10-6 on a .46.  One much more powerfull than a LA .46, so I don't think it is too small.  IMO for tall grass an 11-4 should work fine.  Won't fly very fast though.</p>
