Got my stryker back up in the air but it's a pig.No where near what it use to be.It's been so long I forget what prop I was using.The set up now is jgf 450 2100 mah esc 35amp and the prop on it now is a 5x5 coming down with motor and packs barely warm. Any thoughts on what size I should go up to.

Stock is a 6x4 which flies them fairly well. If yours is a custom setup, what's your motor Kv?

Thanks for the help but I just found out what happened.I need to run a 7x5 prop.I thought I bought the JGF 450th 3000kv when I really bought the JGF 450t 1700kv.

If it's a 1700 kv you'll probably need more pitch. I have a 2000 kv motor and am running a 6x5.5 on 3 cells. It draws 26 amps and flies great.

Thanks for the help Jester
