Props

[DucktileMedia]

Sorry, i couldnt dig up what i was looking for in a search. I just purchased the Avrotos 2814 11s motors and 11x4.7 SF props. I also grabbed the 11x5 graupners to compare. but a few people have told me to utilize the low rpm high torque nature of these 770kv motors, I would better suited with 12" props. Does anyone know where to get a set of 12" APC's? I wish Graupner would make a bigger prop with a pusher set over the 11's...or do they? Another question is the difference in lift from one prop to another with similar specs. I.e. the graupner has much less surface area on their 11x5 than the APC slow fly 11x4.7. So by this logic would the thin APC 13x5 be similar to a 12x5 slo fly?

help!
