RE: Regarding SP series engines, props and airspeed...
Specifically (looking at that site!), I do not understand their propellor sizes... 6A, 8B, 12C, etc. What are they talking about? When I pop open the details they say "for model airplanes from 2.800 to 15.000 g weight"... g as in grams? 15 grams is almost no weight at all compared to a 5 kg airframe! Again, what are they talking about that's 15.000 grams?
Ergo, their site leaves me totally confused as to what blades I'd need. I do not understand their website. [&o] It does look like once you know what size blades you want the adjustable hubs are listed in that blade's category. Looks like they also have different airfoil shapes you can choose from... but you have to know what size propeller you're after (6A, 8B, etc.) and that has me totally confused!
Please advise?
