    Motor stuttering

    Hello, I recently bought a speed build kit for the mighty mini, tiny trainer, along with the power pack a. I built the plane just fine and I have all of the servos hooked up correct but the main motor seems to be having an issue. When the prop is not on the motor, the motor spins fine mostly but...

    Help! Long term solution to an F-pack motor upgrade!

    Hello y'all. I've been flying Flitetest and other mighty mini size swappable warbirds for a couple years now and I REALLY love the redbottom 2205 2300 kv. It outlasts my planes and hauls on 3s and 4s. But for the last year I've been trying some higher kv motors that my buddy lent on and off...

    So, I'm building my own drone and I'm thinking of using a 4S battery on a 1.5 pound or 700 grams drone. I was going to use a 3S, but it's very hard to find testing on the motors that I am trying to get. So around what kV motor should I be looking for? I've been looking at the Mini Quad Test...

    Help! Help with motor and propellors

    I will have a weight of around 1.5 pounds on my drone and want to know what motor with prop combination will get me the most efficiency with a 5500mAh 3c battery. I am new at this but am building a quadcopter that needs to be able to go around 1.5 miles or 2400 meters. I was thinking about 8"...

    Solved BL-Motor making strange sound

    Hi, after a crash of my Tiny Trainer the "nose" of the propeller (Spinner?) and the moving part of the motor (outrunner) had scratches. But when I turned it, it seemed to run perfectly straight. After repairing the TT I made a motor test and found that the motor sometimes(!) makes a strange...

    Horrible motor noise?

    I recently got into the hobby and built my first plane. It is a foam pusher with a carbon fiber arrow for a tail boom. The thing flies pretty well, however the motor is a little concerning. The motor does not respond at all until the throttle stick is about 1/3-1/2 of the way up, but then...
