Setting Up The Speed System - Advance acoustic IOTA 23 User Manual

1
Caution: Even though the I OTA has a high degree of stability in
accelerated flight you should only use as much speedbar as you
feel comfortable with .

Setting up the speed system

The I OTA speed system can, with the help of the SPI, be adjusted so
that the whole speed system travel can be used . The system is cor-
rectly set when pushing the first speed step gives you the 30% posi-
tion, and pushing the second achieves 80% accelerate . Both toes fully
extended should then reach 100% ( pulleys touching ) .
If, by setting the speed bar line lengths, a first adjustment of the speed
system for leg length and harness does not result in the set-up de-
scribed above, fine adjustment is possible by changing the two-stage
settings on the risers . By moving the knots which locate the gear
change balls 1 ( see illustration ) the speed system travel and loading
can be adjusted .
Example: If the knots are moved downwards the changeover
from the 3:1 ratio to 2:1 occurs earlier, raising the loading but
shortening the total travel . Conversely, moving the knots up-
wards delays the gear change, and lengthens the total travel of
the speed bar .
