Go for a few taxi runs and check the steering is not into oversteer. From following the instructions - ours was and we finished up in violent swerves once we had some speed. Point of contact on the wheel must be behind the line of the axle. (Experts call it positive castor)

Assuming OK. For the first flight - use very little or no flap. Apply full throttle. When you have a bit of speed - she will start to bounce. Allow her to lift off but keep her very low for about 20 yards, while she accelerates. The problem you are trying to avoid is that if she is a bit heavy for the speed and you climb out normally and then she goes underspeed, she will go into lateral oscillations. However clever you are on the ailerons, these are hard to get out of. Full power and staying level is about your only hope. We have a prop powered Hawk that can clamber into the air at too low a speed and then plays these nasty tricks. Speed equals safety.

When confident of your speed then climb and turn into your downwind leg. When you have a good height start investigating the stability of the flaps at half movement. Roger of Wren Turbines has a super setup with crowe braking on the ailerons, which is really impressive. However before using the things in the air - check that they balance at height and that they do not provoke a wing tip stall. We tend to be very cautious with the flap even now. Better a fast controllable landing than coming in too slow and tip stalling just as you approach. Do not risk landing with full flap.

Both these photos show the model off the ground and from them you can see how far I travel near the ground to accelerate properly. The first two are in the wrong order.
