This was interesting to build as I haven't ever built a successful helicopter. I couldn't find many people showing the building process on YouTube. I used this to test a mod I installed. To fly push throttle to full power. To move forward or backwards push forward or backward on the pitch. Do not push forward quickly or all the way. Once it has some speed push the trim up or down depending on direction and occasionally use the pitch to maintain speed. To turn do not use yaw. Use roll. The way I used roll is flawed but I couldn't figure out how to do the back propeller so that was the solution that popped up. To lift gears pull down on VTOL. It has rockets and a minigun. This helicopter is not fast and do esnt go to high altitudes. Feel free to modify this to go higher or faster or what ever you want. The custom landing gears are new to me so they don't work well but if you bump the ground it helps it blue so that's something.
