Need help.
Have flown my P3P for a good while now. But today It crashed into a wall of a house. So after picking it up. It was upside down and the battery was dislodged and a propeller broken.
After a quick look, everything seems to be fine aside from the broken propeller. Tried starting it again but no go. I noticed that the app said Weak signal. Tried calibrating but it keeps saying disconnected. Then I noticed that the controller has a solid red led. So I tried linking the RC to the AC but no joy. Every time I would push the link button the aircraft no led would light. Tried pushing it for 2 seconds but still nothing.
What could be the problem and what could be the best solution...

It may be the crash has broken one of the antenna wires. They run down the legs of the landing gear.

Sorry to hear about your crash.
I think a repair service would be the best course of action. I'd suggest you to send it in for further diagnosis and repair.
