If you find the cyclic percentages are very high and the roll and tumble rate are still not fast enough, there is an option! Instead of using the short ball(107-106) on the inner swash, try using the long ball(107-108). These are the balls that connect to the pitch links. IMPORTANT!! If you perform this modification, make sure you trim approximately 1mm of threads off the long ball with a file or Dremel Tool. If you do not trim the threads they will bind with the swash ball housing causing the swash to feel very still.
Another option is to try different set of blades. Unfortunately not all FBL blades are created equally and some have their limits to which no matter how high you turn the swash AFRís the helicopter will not move any faster.
