Trimming system
Notes on the Mantra R07 Trimming system by Ozone Test Pilot, Russ Ogden:
The R07 comes with trim risers as standard. These are also available for the M2 as an optional extra. First of all and most importantly is that the trimmers can be used with confidence - there is not too much travel with them, approx 1.5cm to slow down and 4cm to speed up.For max climb in thermals it is best to pull the trimmers fully on. This reduces the airspeed, sink rate and brake pressure without compromising the handling and with no early stall problems. For maximum handling it is possible trim the glider asymmetrically, with the inside trimmer pulled on fully and the outer left at neutral. The handling is at its best in this position and in strong climbs can be the most effective position. However, please be aware that while in this configuration your wing will be trimmed asymmetrically and the pilot must take this into consideration in the event of any collapse or other maneuvers in flight.
In turbulent strong climbs or in any active air it is best to return the trimmers to the neutral position (where all the risers are the same length).
For most glides it is best to release the trimmers, except when trying to maximize glide while flying downwind in good air. Otherwise, release the trimmers all the way and add additional speed with the speed bar if needed. Another technique is to leave the trims in the slow position and use the speed bar to effect speed, only releasing the trimmers to reach maximum speed.
There are no right and wrongs - it is up to the pilot but we would suggest that the latter method is probably the safest. Normal collapses with the trimmers fully released are manageable, but as with all trim systems we strongly recommend in turbulent air to bring them back to the neutral position and fly the glider actively. At full speed and maximum bar it is best to keep the trimmers in a midway position unless you are confident that the air is smooth enough to let it go all the way.
Cheers
Russ
