Hi!! Everyone I need some advice We are building a f450 quad can someone suggest a good motor/propeller for it we're trying to achieve the longest flight time using a 5000mah 3s battery why this batt. its because it's the only one we can get for a reasonable price here in our country we estimated the quad's total weight to be around 1250 to 1400grams. I have a racestar 2212 1400kv motors here from our first failed attempt hahaha!! yes it is powerful but It's too power hungry so please any advice would be helpful. Thanks in advance!!!!
