Chad is correct,........I run the 21x14 APC on my Pletty and it works very well in all conditions. If I am flying in really windy conditions I will change back to the 20.5x14 as I think it adds the extra punch needed for windy conditions and it pulls about the same Mah as the 21x14 would. I just tried the RASA 20x15 as an experiment,...really fast,.....use way less throttle as it carries more speed at a lower stick position. Also with the 20x15, if you have not gotten use to the EP power you can really put a hurt'en on your packs, if you hammer the throttle throughout the sequence (not practical but useable).


Also,...a thing to remember is guys like Chad, Dave L, Jason and lots of others "others" have done lots of experimental research over the years with different motors, props, batteries, etc to help get EP where it is today. Asking questions is the correct thing to do,....I did and still do, as EP is still new to me aswell.
