Review on Red S37 Altitude Hold RC Helicopter For Beginners And Kids – 3.5 Channel, Sturdy Alloy Build, Gyro Stabilizer, High & Low Speed, Multi-Protection Drone Ideal For Indoor Play by Flex Morgan

The helicopter works great. Quick response and very stable. Unless you are flying outside in moderate to high wind obviously. I find a little tiny bit of wind it can handle fine. Make sure it's on high speed outside and it should be fine. Flight time is decent but the charging time can be long. The getting it off the ground can be tricky at first. You need to push the throttle up once to activate the startup sequence which gets the blades spinning and and the push it again shortly after to confirm takeoff at which point it will begin to hover and you can then adjust the altitude up or down to your liking or hold down to land. Straightfoward if you've done it before similar units but can be confusing for those who have only used the older ones where it takes off as soon as you push up on the throttle. The only issue I've had is the rear propeller can fly off if not securely attached during flight. Overall not bad. Price is meh tho.
