This model is incredibly sensitive to proper weight and balance. Fortunately it is easy enough to check. Simply lift the plane with your fingers directly on the wing spar at both wing tips. This will be your starting balance point and will put you in an acceptable range for a first test flight.

I suggest taking this model to a very large paved parking lot free of obstacles. The wheels are very tiny and with the addition of the wheelpants it is not very forgiving of grass, or rocks. Also, you likely will need the space to taxi around a bit and get used to getting this plane up to speed and continuously pointed upwind. This is where you will get an idea of the control forces. I had to dial my control deflections down to about 50 percent on my transmitter before I found I could keep up with this model.
This tiny model is carrying a good bit of electronics and battery, therefore the wing loading is not incredibly light. It's going to need some airspeed to get airborne. Make sure you have it before leaving the runway. Landing will also be a bit faster than you may anticipate because of both the wing loading and the fact that the wing is a fully symmetric aerobatic shape. There is no dihedral in the wing, and this plane is just as happy flying upside down as right side up. Great if you are a stunt pilot, not so great if you are just learning how to fly. It is a tough little plane though, and will likely take a few scrapes before you have to print out another one.
