Success comes with taking risks.

You're right, my friend.

I remember buying a gas powered 4x4 little car. It wasn't cheap. It needed work and I spent months fixing every little detail. Lots of money, too.

I took it out for a test drive one day. It is capable of 50 MPH.

I get going, and it smashes into a car tire, smashes to pieces. It went in the trash after that. Sighs.

I know what is that feels like... :(
But if we keep learning, trying and practising, we will success.
Drive or fly is not easy, there is still a long way to go.
Good luck for you and every RC hobbiest :D

Last time I got a Parkzone-radian glider, and I was so happy, but when I was flying it, The wind suddenly changed direction, I could not make it turn back, and the glider ends up on a tall tree. It stays there for almost 6 months before it falls off... when it finally falls down, the structure was completely destoryed, but electronic devices were fine...

I have a small 3-channel sturdy beginner RC plane which called "翼龙" （“wing dragon”）, it's a nice plane to fly, I've flown it successfully 5 times.
I also scratch built 3 planes from foam board, and only one was successful. The one I built this time lost control in midair and crashed.
Bad design, overweight and the lack of accuracy are hard to overcome while making your own plane. It's easyer to fly a RC plane which is purchased from stores.

That is impressive! You are your own experimental aircraft pilot!

Thank you! I'll try my best to design and fly my RC planes!

I'd like to see them :)

My pleasure! I'll post the pictures :D
