I’m trying to make planes using nothing but acf and fin tool. However I am having a really hard time making a propeller with just fin and props. I see videos of people making fast planes with fin propellers but each time i try to make one it could only make the vehicle go up to 20 mph. If you know how to make a propeller then can you tell me how to make one myself or things i should do to give it more power. I’ll highly appreciate it.
Note: i already tried increasing the max power of the fin over 100 but it make the propeller struggle to rotate and when it does rotate at a proper rpm but i still get only 20mph on the ground
