I'm gonna buy me APC 11X5 and 11X4 and try both of 'em especially their thrust & vertical climb. Should I go for APC or Master Airscrew? in fact I had been using APC mostly, I like MAS's S-2 Scimitar series as well. With these 2 props, I'm gonna play with the throttle and vertical and slow fly byes. Tomorrow my new ASP .52 is being delivered and for break in I'm using MAS 11X7 and I bought 11X8 for the future use, but as of today's discussion I'm gonna change APC 11X8 to 12X6, also I'm kinda indecisive between these 2 planes.

I'd certainly post the results of 11X5.
