Can you give me some prop suggestions for my 6s tfl Pursuit. Right now I have a gratinar k45 prop which is 45 mm and I'm getting 47 miles an hour with a hobbywing Seaking 180 V3 and a castle 1717 1650kv motor from an X Maxx. The batteries are lectron pro 5000 3s 50c and I know they're holding me back right now because they're the only thing getting warm. I tried a 42mm CNC 2 blade prop and the speed dropped by five miles an hour. I'm ready to start sharpening and balancing my own props but I'm not sure what probably should start with and money is tight. Obviously I plan on improving the batteries for a higher C rating and maybe going up to a 6,000 or 7,000 milliamp hour
