A value of zero means to bypass the initial &quot;tail hold&quot; stage of takeoff. Set to zero for hand and catapult launch. For tail-draggers you should normally set this to 100, meaning full up elevator during the initial stage of takeoff. For most tricycle undercarriage aircraft a value of zero will work well, but for some tricycle aircraft a small negative value (say around -20 to -30) will apply down elevator which will hold the nose wheel firmly on the ground during initial acceleration. Only use a negative value if you find that the nosewheel doesn't grip well during takeoff. Too much down elevator on a tricycle undercarriage may cause instability in steering as the plane pivots around the nosewheel. Add down elevator 10 percent at a time." user="User">

When enabled, the percentage of flaps is taken as the percentage travel from the TRIM value of the channel to the MIN value of the channel. A value above the TRIM values will give inverse flaps (spoilers). This option needs to be enabled in conjunction with a FUNCTION setting on an output channel to one of the flap functions. When a FLAP_IN_CHANNEL is combined with auto-flaps the higher of the two flap percentages is taken. You must also enable a FLAPERON_OUTPUT flaperon mixer setting if using flaperons." user="User">

Some parts of the world may have higher resolution data available, such as 30 meter data available in the SRTM database in the USA. The grid spacing also controls how much data is kept in memory during flight. A larger grid spacing will allow for a larger amount of data in memory. A grid spacing of 100 meters results in the vehicle keeping 12 grid squares in memory with each grid square having a size of 2.7 kilometers by 3.2 kilometers.
