Thanks...
I don't recall saying control sensativity was a major issue. It takes a bit of getting used to especially transiitioning from flat terrain forward motion to downhill...steering control inverts and essentially becomes opposite to what is intuiative.
A set of disc brakes on the jack shafts would help alleviate some issues.
I can change control sensativity by changing the distance the annular pistons must move to actuate the clutches inside the transmission and beleive me it makes a big difference with small adjustments.
As it is I am quite comfortable with how the controls are all dialed in at this time.
read back through and find the video depicting the transmissions annular pistons and you will understand more fully
