Fine Tuning & Radio Hints

Up to this point we have been using basic throttle and pitch curves with no mixing other than setting the Gyro gain potentiometer. Now it is time to fine tune the settings for your flying level.

You should be comfortable enough with your radio so that you can reach all of the sub-trims, switches and dials while in flight. Specifically the sub-trims.

Note: The following instructions assume you already have the skill necessary to maintain a steady hover. If you lack those skills, I highly recommended that you take the

RADD'S School of Rotary Flight Training Courses located at:

The first step in tuning is to get the helicopter to hover free hand for at least two seconds. Place the helicopter into an eye level hover and use the right side sub-trims to get the helicopter to hover level, Apply as much sub-trim as required to accomplish this. Once obtained, go back to the computer, and adjust the electronic sub-trims to that you can bring those cyclic sliders back to center point.

You may need to test fly and readjust the software multiple times to get the mechanical sub-trims back to center.

At this point you should have a well behaved albeit wimpy helicopter hover. Now you can adjust the throttle curve to provide more head speed in the range of flying you intend to work in. We originally set the throttle curve to a linear 0-100 setting. With higher head speed, the model will have crisper control at the same pitch. You can alter the curve to give yourself a nice head speed at your normal hover zone of the left stick. You will notice that it takes less throttle to maintain a hover, and the helicopter is more controllable. We started off with the lower throttle and pitch settings to help avoid too fast a reaction from the helicopter as we made adjustments.

Throttle curves and Pitch curves are joined in their operation. Each has an effect on the other, therefore as you tune the helicopter to your flying skill keep in mind that adjusting one curve may require adjusting the other as well.

You can return the pitch settings of the software and dial in a negative starting pitch to something like -2 (physical pitch) for the NOR setting on EP01. This is done my setting the value to something around 40. Then position 2 to something like 50. Depending on what you want to do, you can ramp up the pitch quickly for more radical jumps, but be aware of the limitations of your tail gyro and servo. It may not be able to compensate for the rapid increase in pitch and the tail will blow out on a vertical punch out. Make sure you adjust the throttle curve to give your tail rotor a chance in countering the increasing resistance as the blade pitch increases.

Negative pitch in normal mode always causes controversy in RC Helicopter groups. For anyone that has ever had a gust of wind come up and pop your helicopter into the air will appreciate the ability to apply negative pitch to get the helicopter to counter the updraft.
