You ask what can go wrong?
1st an foremost your safety and those that are with you when something does go wrong.
Incorrect balance of a new airplane.
Building errors.
Cheap arfs that have just barely enough glue to hold the engine mount in place.
Control throws setup backwards.
I have witnessed antennas coiled up left inside airplanes.
Not enough or not the correct type of rubber bands on the wing at takeoff.
Panic when a student 1st starts out in that they apply full input of the sticks or the give it more of what the airplane doesnt need in direction.
Pilot gets disoriented in flight and freezes to watch their airplane become rekitted.
Flying towards you inputs.
You can fly for months without a mishap on the flight sims, but if the controls are not setup similar to how a RC operates then the flight sims are NO GOOD. In order for a flight sim to have any merrit it has to be setup by a experienced pilot then an only then is the flight sim of any value.
Too many new pilots have come an gone away from this hobby discoureged because they tried it alone an failed because they did not seek advice.
There are too many varables that have to be in place in order for someone to make it on their own.
The only reason that we STRESS to get HELP is that we don't want to see you fail because you did not prepare before hand.
If you truley want to get into this hobby then start out at the correct point so that you can get to SOLO status.
This is not a self taught hobby! Grant it some have made it past the earlie stages but ask them what they have had to go through before they made it.
Safety can't be stressed enough, our airplanes are not toys!
Ask your self honestly, with the investment that I have made to get a complete airplane setup and have everything that is needed to fly, am I 100% confident in everything that has been done in preparation to fly this new airplane.
Are you willing to take the chance to try it ALONE.
If you do what is the worst thing that can happen!
You could hurt yourself or someone close to you.
You could lose your entire setup.
Just food for thought :-)
