First Flights
Diode Voltage Drop - To lower voltage of a supply source

Changing to new version swashplates and carbon main shafts should have added some screws. On the ones with Delrin main gears, you can grab extra screws from the ring collars as the thicker Delrin main gears should allow the main shaft to drop without disengaging the pinion.

Then you have gobs of extra screw that can be robbed from the dual-charger and transmitter.

Reminds me, when putting screws back into plastic, turn the screw backwards (out) until you hear a click as the screw finds the original threads, then turn the screw in. Avoids stripping the plastic threads.

First Flights
If you have problems getting into the air, try getting the helicopter quickly to eye level to get out of the ground effect, or hand launch if all else fails. You may find a slow lift-off causes the helicopter to scoot left, so be prepared for it. A slow lift-off can be done smoothly after you learn to control the helicopter.

A good launch pad is a (soft) cardboard box about 2 feet high. Then fly forward off the edge into clean air. The helicopter will drop but you already are adding throttle so just keep adding more.

All my V911's will violently scoot left (viewed from tail) on take off. I think it is the tail rotor pushing it left. When in the air, there is a right tilt on hover which means the left drift is being corrected by right aileron. That is the way they hover, even after setup...Continue Reading

V911 Wind-Surfing

Many flyers wind-surf with V911's because you can try anything with a V911, not fearing a damaging crash - worst case, $20 V911 BNF, just buy another one and use the old one for parts. If you are afraid to crash, then don't wind-surf.

Start by not using ailerons. Rudder is much quicker.

Apply full forward trim to keep the nose from coming up too high, and fly low, to avoid letting the wind get it.

Practice hovering nose into the wind . Push the nose down and apply throttle to hold position or to move forward.

To gain forward speed when nothing else works, turn to the side and fly a crosswind zigzag pattern.

Practice nose-left (counter-clockwise) circles to fly around and nose dive into the wind again. Ease up on the nose and bank one way or the other into the oncoming wind. Nose-right circles may be faster but harder to control (recover) after you get downwind.

Lots of practice. In calm or little wind, practice nose-left circles: Nose down to get forward motion, then full left aileron followed by small amount of left rudder, then aileron neutral, gets smooth banked wide circles. Use rudder to control diameter and throttle to maintain altitude, or allow the helicopter to dive close to the ground under the wind.

Forgot to mention that you always keep moving, crosswind zigzag, or circling back. Zigzag picks up speed when you turn. Circling back picks up speed downwind after turning into the wind and diving into the wind head-on. The fun part is at...Continue Reading
